Groundhog sees his shadow--six more weeks of winter?

By: Dr. Jeff Masters, 3:24 PM GMT on February 02, 2008

Punxsutawney Pennsylvania's famous prognosticating rodent, Punxsutawney Phil, saw his shadow this morning. According to tradition, this means that a solid six more weeks of winter can be expected across the U.S. From the official web site of the Punxsutawney Groundhog Club, groundhog.org:

Here Ye! Here Ye! Here Ye!

On Gobbler's Knob on this fabulous Groundhog Day, February 2nd, 2008
Punxsutawney Phil, the Seer of Seers, Prognosticator of all Prognosticators,
Rose to the call of President Bill Cooper and greeted his handlers, Ben Hughes and John Griffiths.

After casting a weathered eye toward thousands of his faithful followers,
Phil consulted with President Cooper and directed him to the appropriate scroll, which proclaimed:

"As I look around me, a bright sky I see, and a shadow beside me.
Six more weeks of winter it will be!"


I'm hesitant to disagree with a forecaster of Phil's stature, but I see only about of week of hard-core winter left over the U.S. The 16-day run of the GFS model shows the jet stream retreating to a position in southern Canada in about a week, which will usher in mild temperatures for this time of year across most of the U.S. The latest 1-month outlook from NOAA's Climate Prediction Center shows an above normal chance of warmer than average temperatures across a large portion of the U.S. for February.

How did this this crazy tradition start?
It all started in Europe, centuries ago, when February 2 was a holiday called Candlemas. On Candlemas, people prayed for mild weather for the remainder of winter. The superstition arose that if a hibernating badger woke up and saw its shadow on Candlemas, there would be six more weeks of severe winter weather. When Europeans settled the New World, they didn't find any badgers. So, instead of building wooden badgers, they decided to use native groundhogs (aka the woodchuck, land beaver, or whistlepig) as their prognosticating rodent.

The Groundhog Oscillation: convincing evidence of climate change
According to a 2001 article published in the prestigious Annals of Improbable Research titled, "The Groundhog Oscillation: Evidence of Global Change", Punxsutawney Phil's forecasts have shown a high variability since 1980. This pattern, part of the larger "Groundhog Oscillation" or GO cycle, is convincing evidence of human-caused climate change.

Good Morning DrM. I hate to know we have 6 more weeks of winter.
Sheri
hey StormW
Good morning

Thanks Dr. Masters. Punxsutawney Phil and Ground Hogs Day are big in PA. Six more weeks of winter isn't bad.
No winter down here in South Florida almost feels like summer outside...Its been a pretty warm winter all in all with a few strong cold-fronts from time to time.

Hope everyone has a fantastic weekened!

Thanks, Dr. Master! Winter until Mid-March, isn't so bad.
Hi 23

Did you get my mail?
Okay, I just posted on my Blog weather updates for
Thursday's Space Shuttle Launch from the Cape, any
Idea's what the Weather may be like on Wed/Thursday because i heard about a Cold front.
i no hurricane23 it always feels like summer down here in south florida
PUNXSUTAWNEY, Pa. - Brace yourself for more wintry weather. Punxsutawney Phil saw his shadow Saturday, leading the groundhog to forecast six more weeks of winter.


The rodent was pulled from his stump by members of the Punxsutawney Groundhog Club Inner Circle, top-hat- and tuxedo-wearing businessmen who carry out the tradition.

Each Feb. 2, thousands of people descend on Punxsutawney, a town of about 6,100 people some 65 miles northeast of Pittsburgh, to celebrate what had essentially been a German superstition.

The tradition is that if a hibernating animal sees a shadow on Feb. 2 — the Christian holiday of Candlemas — winter will last another six weeks. If no shadow is seen, legend says spring will come early.

That was the forecast from Gen. Beauregard Lee, Punxsutawney Phil's counterpart in Lilburn, Ga. Beau did not see his shadow Saturday morning at the Yellow River Game Ranch.

It was the third year in a row the two groundhogs' predictions differed.

Of astronomical note, February 2 is also a cross-quarter day, the half-way point between the winter solstice (first day of winter) and the vernal equinox (first day of spring). In northern Europe, before the adoption of the Gregorian calendar, the cross-quarter days were the actual start of the seasons--February 2 was the first day of spring at that time. This is why June 24 is called Midsummers Day in England, even though now it is a few days after the summer solstice. The New Year actually was celebrated in many places on the date of the vernal equinox (around March 20); until Britain (and the American colonies) adopted the Gregorian calendar in 1752, the New Year started on March 25, not January 1--thus the references to George Washington's birthdate as being February 11, 1731 Old Style, or February 22, 1732, New Style. The other cross-quarter days had some type of celebration around them as well--May 1 (May Day),the first day of summer, October 31 (Halloween), the first day of winter, and August 1 (Lammas, now virtually forgotten), the first day of autumn.
Did groundhog see 6 more months of insane la nina too?
You can have your 6 more weeks of Winter.. I am going to mow the lawn then go golfing :)
Storm, another question for you :)

We have decided the next vacation in December is going to be to Jamaica. There are three resort area on the north coast and one on the southwest coast... which would be more likely to give us the better weather for sunning and snorkeling?
Thanks Dr Masters, living in Southern Ontario, it does not really matter if Wiarton Willie sees his shadow or not, its a given that there will be 6 more weeks of winter, now whether they be mild or continue on their present course is yet to be determined...Lets hope the worse is over...
NOOOOOOOO!!!!!!!! :-) Okay, it's fine up here in Fairbanks, but I wish winter in WY would settle down!
"...Punxsutawney Phil...The rodent was pulled from his stump by...businessmen..."
so there is no way to know whether the groundhog would have come out on it's own, and thus no way to know whether it would have seen it's shadow.

Since the prognostication is not based upon "if a shadow is seen by anybody" which would require neither a badger nor a groundhog, whether the animal itself chooses to come out of its burrow is a necessary precondition of obtaining any forecast based on folk wisdom.
aspecture, I remeber back in 1994 when they pulled out the groundhog when it was -6F and the groundhog was shivering and shaking so much it looked like he was having convulsions! It seemed horribly cruel.
If anyone is intetested, I have made a blog, about this year's La Nina (Will it continue)? Click my name.
It probably was horribly cruel, StSimonsIslandGAGuy.
Hibernating mammals slow down their metabolism by an incredible amount. eg Ground squirrels can tune down their body temperature to only a few degrees above 0*Celsius/32*Fahrenheit. Arctic squirrels actually go below that freezing point.
While biologists don't know the precise mechanics of how mammals arouse themselves from hibernation, it is known that brain activity and various bodily functions undergo non-synchronous cycling of speed-ups during the process of gradual warming. Forcing them to awaken when those cycles and body temperature haven't yet reached normal has gotta do harm.
And things that harm the body tend to feel physically unpleasant, often extremely so.
Hmmm... Saw his shadow? Doesn't really look like 6 more weeks of winter:

Tonight: Areas of freezing fog after midnight. Partly cloudy, with a low around 26. Light north wind.
Sunday: A 40 percent chance of showers after noon. Areas of freezing fog before 8am. Mostly cloudy, with a high near 43. East wind between 5 and 13 mph.
Sunday Night: Showers likely, mainly before midnight. Cloudy, with a low around 38. South wind between 8 and 14 mph. Chance of precipitation is 60%.
Monday: A chance of showers, with thunderstorms also possible after 9am. Cloudy, with a high near 61. South wind between 8 and 16 mph, with gusts as high as 28 mph. Chance of precipitation is 40%.
Monday Night: Showers likely and possibly a thunderstorm. Cloudy, with a low around 48. South wind between 11 and 17 mph, with gusts as high as 24 mph. Chance of precipitation is 70%.
Tuesday: Occasional showers. Temperature falling to around 43 by 5pm. Chance of precipitation is 80%.
Tuesday Night: A chance of rain before 9pm, then a chance of rain and snow between 9pm and midnight, then a chance of snow after midnight. Cloudy, with a low around 27.
Wednesday: Partly sunny, with a high near 39.
Wednesday Night: Partly cloudy, with a low around 28.
Thursday: A chance of snow or rain. Mostly cloudy, with a high near 44.
Thursday Night: Mostly cloudy, with a low around 31.
Friday: Mostly sunny, with a high near 45.
Friday Night: Partly cloudy, with a low around 28.
Saturday: Mostly sunny, with a high near 43.


Highs near 60 and thunderstorms are not winter weather around here (some of the snow I had the other day has already melted as well and will be gone in a few days - at least I did have two major snowfalls this winter, both the largest in years - but otherwise it has been very much unwintery, with record warmth, tornado outbreaks (more severe weather possible in a few days) and very few snowfalls, the snow amounts aside).
Yeah, I think it's pretty safe to say this winter is over. There won't be another 6 weeks of winter I don't believe. This winter is seriously the warmest winter I've observed in at least 4-5 years in Louisiana (judging from my memory, not records). I don't see winter lasting even 2 more weeks, much less 6...
ROTFL! The Holy Grail!

There's no going back, now, Dr. M! Your secret is out. A Monty Python fan, eh?
I don't see winter lasting even 2 more weeks, much less 6...

It may be warm for the next month (based on forecasts and outlooks), but I wouldn't be surprised if we have another major freeze in late March or April, like the last two years (particularly bad last year because it was later and followed a near record warm March, with several billion in crop losses).
oh man, he saw his shadow.. he should have been where I live. (it was cloudy most of the day) HAHA

I didn't think about that when I posted. Come to think of it, that may actually happen. Talk about freakish cold. Last year's March/April freeze was some of the coldest air I've had to endure, since Louisiana doesn't get cold all that much.
StormMan: How do you know most of that stuff isn't from La Niña? I don't know all of the effects it has on land, but I do know that the snow in China may have been influenced by La Niña, which is quite strong at the moment.
KMan,

I appreciate your question..but, most of those links I posted were for weather items that are unique over an extended time period, several are records unbroken for 40-100 years. If just a La Nina vent would not be as notable. Plus, this La Nina vent is not only fairly weak it is practically over if you check the temps on the eastern side of the Pacific.

Or just observe how much precip has been happening in California/Arizona and the deep south...a strong La Nina would have those places mostly dry, right? Over the past several weeks each has received weekly storms.

Or consider that 2007's records in the Southern Hemisphere occurred previous to this most recent La Nina episode (snows in S.America and S.Africa)

A prolonged "near-neutral" period with volatile SST conditions has clearly been replaced by more or less stable La Nina conditions in place since late August 2007.
....SYNOPSIS....

GULF OF MEXICO/NORTHWEST ATLANTIC OCEAN WEST OF 50W....

A broad 250 hpa zonal west-southwesterly flow has develop across the Southeast Portion of the Continental United States in associated with an upper trough across the Rockies and an upper ridge over the Caribbean. This flow is advecting a swath of broken to scattered cloudiness and showers from Northern Mexico across the Southern Plains and into the Deep South and Atlantic Corridor. Meanwhile, a weak ridge protrudes across Gulf of Mexico region providing exceptionally fair weather across the Gulf waters and surrounding regions of Mexico, the Yucatan and the Florida Peninsula. The return flow is also providing an onshore flow, which is enhancing the moisture plume outlined earlier.

A broad ridge is analyzed across the Atlantic based on satellite imagery and surface observations through 1330 UTC. The region lies within the downstream area of the upper ridge across the Caribbean providing for a stable troposphere...thereby fair weather dominates. Patches of shallow cloudiness and brief showers is seen within the moist but thin surface layer.

CENTRAL AMERICA AND THE CARIBBEAN REGION....

Trades have really increased across the Caribbean due to the merger of the Bermuda and Azores ridge. This is creating an influx of tradewind moisture and chilly air into the Caribbean with linear patches of cloudiness and passing showers moving from the Atlantic, across the Lesser Antilles, through the Caribbean basin and then across the Central American Terrain. The cloud features become more broad and deeper west of 70W indicating more heating and moisture transfer below the cloud bases here.

Well, i am hoping that Dr.M is correct --I've already had enough cold fronts. Looking forward to surfing without the rubbersuit on. Glad to see the regulars still on & posting. Been swallowed up by work at the Polo Club. Not looking for the hot temps. of summer (the horses in FL suffer so) but living in the 70's would be a pleasure. What I am curious about - is RAIN --do any of you weather "pros" see a wet spring/summer??? Pastures are so dry, grass and hay are very poor and difficult to find.
Vry nice synopsis W456 - Love the infor on the Gulf.
STormW - if your on Good morning and as always great appreciation for your weather updates...I've been quiet, working too many hours, but I ALWAYS LOOK for your forecasts!!!! :)
Wiarton Willie says the winter that has ravaged most regions of Canada this year will give way to an early spring.

The country’s most famous weather prognosticating rodent failed to see his shadow when roused from his slumber this morning.

An early spring is also the prediction of Canada’s other famous groundhog, Nova Scotia’s Shubenacadie Sam. But Pennsylvania’s Punxsutawney Phil disagreed. He saw his shadow when roused from his slumber by his handlers.

Staten Island Chuck is calling for an early spring. He apparently saw no shadow on emerging around 7:30 this morning from a small house at the Staten Island Zoo. City Council Speaker Christine Quinn announced the creature’s finding.

Guess most of us are in for an early Spring while others will still see nasty weather..Glad its not here....
Well, it sure still feels like winter here today in southern California. Under rainy skies and it has been downright cold this winter so far. I wouldn't mind a bit of moderate temps for a while. Guess we'll just have to wait and see what really happens.
surfmom, thanks....
what is the forcast for wind shear overe the next few weeks???
hmmm...winter? here, todays like is like 83 lol. LOL

LOL... You obviously don't know anything...

Compare to the record 1988 La Nina:



1988 0.7 0.5 0.1 -0.3 -0.9 -1.3 -1.4 -1.2 -1.3 -1.6 -2.0 -2.0
1989 -1.8 -1.6 -1.2 -0.9 -0.7 -0.4 -0.4 -0.4 -0.4 -0.3 -0.2 -0.1

Weak? Over? ROTFL... Nino 3.4 at an ice bath -2.2 degrees C (Nino 1 2 hardly counts, as you can see from its size and location - during the 1998 La Nina it was still well into the El Nino range until the end of 1998 and even then only briefly went significantly negative)...



Oh, as for California:

According to Kelly Redmond of the Western Region Climate Center in Reno, all of California's top 10 floods occurred during La Nina winters. Potential weather impacts for California include a jet stream farther north than usual and below-average precipitation from about Interstate 80 and Lake Tahoe south into Southern California.
Last Friday Ice Storm recap for North Carolina.

# Schools were either closed or in some cases where I live a 2hour-delay.

#Some mountains got over a half-inch of ice and lost power when the winds picked up.

# Airplane from Atlanta,G.A crashed over the foothills of N.C killing all pasengers.

# I have never seen such "Heavy Freezing rain".Trees fell and blocked some of the roads and banks beside the road were froze and portions of the porch where the water was not runing so fast were froze.Also, the vehicals were froze.

6more weeks to go.

My overall point of my initial post was to point out there is a lot of coldness going on.

And the question about this being caused by la nina, ok, sure, let's say it is...what caused la nina...? since is a cooling of the equatorial waters of the Pacific...folds into my initial post about the sun being quiet (less output=more cold)



Strong quake in Africa kills at least 40: officials, hospitals
03/02/2008



KIGALI (AFP) - A strong earthquake shook the African Great Lakes region on Sunday, killing at least 34 people in Rwanda and six in the Democratic Republic of Congo, according to officials and hospital sources.

Houses crumbled and deep cracks spread up the walls of buildings in the centre of Bukavu in DR Congo, near the epicentre of the quake which measured 6.0 on the open-ended Richter scale.

People ran out of churches packed for Sunday mass as the walls shook.

"According to the figures I have at the moment, 34 people are dead," said Rwandan local government minister Protais Musoni on Sunday afternoon.

The quake struck at 0735 GMT some 20 kilometres (12 miles) north of the DR Congo town of Bukavu.

Across the border to the east, Radio Rwanda said 10 people were killed "straight away when a church collapsed" in the Rusizi district of Western Province and 13 others died in Rusizi and Nyamesheke districts.

Local authorities in the DR Congo said six people had died in the Sud-Kivu region, according to UN-sponsored Okapi radio.

Provincial health officer Manou Burole said 55 people had been wounded there.

Several dozen injured were admitted to the city's general hospital and at least 12 casualties to the Panzi hospital, medical sources said.

Radio Rwanda said 250 wounded were transported to various regional hospitals, and a witness in Rusizi district said public buses were used to transport the casualties.

Rwandan minister Musoni said that the provincial governor was on site and that the police and army were helping with rescue operations.

"Rescue operations are continuing to try to pull people out of the ruins of their houses," he said.

In the DR Congo town of Kabare, north of Bukavu, the walls of a church collapsed on the congregation during the mass, injuring 37, including five seriously, priest Leon Shamavu told AFP by telephone.

A first shock, which lasted around 15 seconds, was followed by two lesser aftershocks, residents of DR Congo and Rusizi said.

"People are panicking so much they're afraid to return home. They're afraid of being surprised by aftershocks and prefer to stay outside," a Rusizi resident told AFP.

The quake was also strongly felt in neighbouring Burundi, south of Rwanda, Francois Lukaya, a scientist at the Goma observatory in North Kivu told AFP.

All Burundian hydroelectric dams stopped, causing a half-hour power cut, a water authority official said.

The quake also shook the Burundian capital, Bujumbura, around 120 kilometres south of its epicentre.

"I felt a very strong shock shake my house. The walls shook really hard," a resident told AFP.

It was one of the "biggest earthquakes ever recorded in the Kivu region," Lukaya told AFP.



For anyone living in the New Orleans Metro I have a question. I heard that the MRGO is going to be dammed up. Is work progressing on this, and if it is, how close to done are they?
Tropical Cyclone Gene.....dry air intrusion broke down the core of the storm earlier but has since then rebuild back the northern (northeast to be specific) "eyewall".

Gene looks alot like wilma appraching s fl.
Oh dang, Wilma was horrid, I Mean, every single Hurricane that i have been hit by were eaither near CAT-5 or CAT-5 (Floyd, Isabel, Wilma) Isabel was the scariest, because it was so watch, and it was so scary to see that it was maintaning CAT-5, I was so scared that it might ram into my house with 175 mph winds. Wilma being tied with Isabel, not only the fact that it was the strongest Atlantic hurricane to ever form in the Atlantic, it was like a 3 hour fly to were it was. I was scared that it going to hit us directly, (GFDL said this, oh boy scary)
Floyd bing the fact for no apparent reason, turned from hitting Florida, strait into me. (Yes i know why it turned, but this scared me into beyond scared.)
And the question about this being caused by la nina, ok, sure, let's say it is...what caused la nina...? since is a cooling of the equatorial waters of the Pacific...folds into my initial post about the sun being quiet (less output=more cold)


Hmmm... How come 2007 had the hottest land temperatures ever recorded??? Land cools down faster than water... so if low solar output were the cause of the cooling over the last year, than land would have cooled down far faster (not to mention, solar activity is rising, according to this - also note that the biggest solar cycle was in the 1950s... how come global temperatures rose since then?)

As for La Nina, it is caused by a natural fluctuation (Southern Oscillation). The 1988-1989 La Nina occurred as solar activity was increasing (and the 1997-1998 El Nino was in a solar minimum, I don't really see any correlation between ENSO and solar activity).

In addition, even as La Nina cools the surface of the ocean, massive amounts of heat are being absorbed beneth the surface (the Pacific absorbs heat during La Nina and neutral periods and releases it during El Ninos; all of the El Ninos, one every other year over the past 5 years (2002, 2004, 2006, usually every 3-7 years or so) likely depleted the Pacific of heat):



As long as the trade winds remain strong (like right now), that will be kept in check... but I have to wonder what kind of El Nino we might see if that 6 *C anomalies water moves east...



Also, as for some not-so usual effects, some La Nina winters have been wet in the Southwest, even as the summer is usually dry (as I posted before about California's worst floods occurring in La Nina winters, despite typically dry conditions). Also recall that the last El Nino brought extreme drought instead of rain, seems like ENSO is no longer having the usual effects, at least for the Southwest U.S (there is also still drought - it apears to be shifting into the Plains states this year, especially Texas and Oklahoma - actually similar to 2006 which began with a La Nina, although a much weaker one, too early to tell if an El Nino might develop later this year, especially not until around June due to the "predictability barrier").

It has been a La Nina but indeed January was wet for most of California including LA.

Feb. isn't looking quite as wet but we'll see!

Out here in Washington we call them Marmots.
Puerto Rico had a 5.0 quake this morning!

How are all our peeps down there?

Thanks, Dr. Masters.

Usually I say,
If the groundhog sees his shadow we'll have six more weeks of winter
if not, it's just another month and a half. Ha!

But ONE more week? That would be unprecedented here in Vermont.

Candlemas is not only a holiday that was observed in England,
it is still observed by several denominations today.
It was when a lot of people made their last batch of candles for the winter.
So they needed some idea of how hard to work that day! Ha!
I still hand-dip candles each year on Candlemas.
(A tradition we started while studying the American Revolution, home schooling.)
They make great Valentines or Easter gifts.

One more week? Can't wrap my mind around that. Nosirree.
magnitude9...

Do you have a celebration and call it Marmot Day?
Groundhog Oscillation, LMBO!!
{ { { Hope you're feeling better soon Storm! } } }

Take care. ♥
mobal...

Yeah, that is a rather, er, playful term, isn't it? LOL!
VERMONT: The New Connecticut

We would truly miss the sugar maples.
And with the level of unexplained bat deaths this year,
the mosquito population would explode.

EEK!

I want my sub-zeros back!!
Hello everyone. One of the nicest winters I experienced in E Cent. Fl. Very pleasent weather. No more red tide zero so come on down if you need a break from the cold. Good surf too.
I would definately say that the groundhog was wrong:

Amazing how fast snow melts when it is in the mid-70s... the normal high is only 41 (and I wonder why I have NEVER seen a high or low that was 30 or more degrees below normal, much less a daily average, while highs/lows/days that are 30 or more degrees above normal are a dime a dozen)?
Excellent point, MichaelSTL.
The current La Nina is still quite strong (certainly the strongest we've seen in years). It is also notable for the odd distrbution of SST anomalies, especially over the western half of the Pacific. That 1988 vs. 2008 map is very telling--the range of strong negative anomalies is actually quite staggering when one sees them over the entire basin. Because, as you mentioned, cold ENSO events (La Ninas) store heat in the deeper reaches of the ocean, the upswing of the thermodynamic pendulum has the potential to be extremely impressive (imagine those negative SST anomalies translating into positive anomalies of a similar magnitude over a similar area. Wow.) If we do get an El Nino of that magnitude, well, let's just say that it would be an interesting 18 months to come...

I'll have a new seasonal forecast up on Weather West at some point in the next 2 weeks, and it'll consider the influence of the ongoing La Nina regime...
