Deep freeze in the South continues

The Deep South shivered through a ridiculously frigid weekend, with low temperature records crumbling over much of Florida, Texas, and Louisiana. This morning, record lows for the date fell in Miami, West Palm Beach, Tampa, Fort Myers, Lakeland, Tallahassee, and St. Petersburg. The most extreme low temperature record this morning was set in Key West, where the mercury fell to 42°F at 5am--the second coldest temperature ever observed in Key West. This is just 1° warmer than the all-time coldest temperature observed in Key West--41° in January of 1981 and 1873. Widespread reports of sleet and snow flurries accompanied the cold blast across Central Florida on Saturday, the eighth snow event in Florida since 2000, according to Wikipedia. It remains to be seen how much damage the $9.3 billion Florida citrus industry will see because of the cold blast, which is the most severe in Florida since the December 1989 cold wave that devastated the citrus industry. Temperatures below the 28° that causes fruit damage affected some citrus-growing areas again this morning, for the third consecutive morning.

Intense and long-lasting cold
In Texas, two airports tied all-time January low temperature records on Saturday morning--Hondo, who's 12°F tied the record set January 11, 1982, and Cotulla La Salle, which hit 16°F, tying the record set January 13, 1975. Most of Texas' airports set daily low temperature records on Saturday morning. Saturday's low in Waco of 8°F broke the previous record of 15° for the date, and was the first time Waco has been in the single digits since the -4°F reading on December 23, 1989. Not only has the South's cold been intense, it has been exceptionally long-lasting. Montgomery, Alabama has had a low temperature below 25° nine consecutive days, breaking the old mark of seven straight days set in January 2001. With the cold snap only grudgingly scheduled to release its grip on the South, Montgomery can expect to run their streak of sub-25° lows to at least eleven straight days this week. Mobile, Alabama and Pensacola, Florida now have their second longest streak of days with a minimum temperature below freezing, at nine and eight days, respectively. Pensacola may equal or top their record of eleven straight days (set in January 1940) later this week, but Mobile is unlikely to break their record of fifteen straight days (set in February 1940). Also of note is that Key West has seen five consecutive days with low temperatures below 50 degrees (January 7th - 11th). This is the second longest such streak recorded in Key West, one day short of the record six-day streak on December 1 - 6, 1876. Key West has a decent chance of tying that record on Tuesday morning, when the low should fall to 50 or below.

A nicer beach weekend in Antarctica than Central Florida
Saturday's high and low temperatures in Orlando and Daytona Beach, Florida were 40° and 30°F. Tampa's high and low were 42°F and 29°F. Under sunny skies and light winds less than 10 mph, Saturday's high and low temperature at San Martin Base, Antarctica were 44° and 34°F. Gray, cloudy skies with winds gusting to 16 - 21 mph greeted beach goers at the beaches near Daytona Beach and Tampa, so it was a much nicer day at the beach in the Antarctic Peninsula than in Central Florida on Saturday (the Florida Chamber of Commerce loves stats like that!) Nice beach weather in Antarctica continued through Sunday, with sunny San Martin, Antarctica (high 41°, low 35°) recording an average temperature warmer than most stations in Central Florida. In all fairness, it is summer in Antarctica, and the ocean temperatures in Florida were a bit warmer than in Antarctica.

A major pattern shift coming
As I noted in my previous post, a sharp kink in the jet stream and a strong negative phase of the North Atlantic Oscillation is responsible for this winter's cold blast over eastern North America and Europe. The ridge of high pressure that has been blocking the west-to-east motion of weather systems over the past ten days is weakening, though, and a major shift in the winter weather pattern is in store for the Northern Hemisphere by late this week. A more typical El Niño pattern will set up, with the jet stream diving southward over California, bringing a strong flow of moist, Pacific air to the West Coast. A strong low pressure system will also bring heavy rain to the Gulf Coast on Friday and Saturday. Temperatures will slowly moderate across Europe and the Midwest and Eastern U.S. this week as the pattern gradually shifts, and more ordinary winter weather can be expected in these regions by next weekend.


Figure 2. Departure of the surface temperature from average for the first eight days of 2010 shows much colder than average conditions were present over the Midwest and Southern U.S., much of Europe, and Central Asia. Much warmer than average temperatures were present over the Northwest U.S., Greenland, the Arctic, and Southern Asia. A sharp kink in the jet stream was responsible for the temperature anomaly pattern. Image credit: NOAA/ESRL.

I love the weather! Everything about it and always have. The more extreme the more exciting and interesting. BUT I am so over this cold stuff. It isn't supposed to be FREEZING night after night in FL. I usually spend every evening on my patio. It's my living room. I've been inside now two weeks. ENOUGH. And it not just that it's cold. I'm from New England I can deal with cold. It just doesn't fit with Florida Living!

Wind Warning : Greater Victoria
Issued at 3:33 PM PST Monday 11 January 2010

Summary

Southeasterly winds of 50 to 80 km/h will develop this evening over West Vancouver Island, East Vancouver Island, the Sunshine Coast, Southern Gulf Islands, and Greater Victoria. This is a warning that potentially damaging winds are expected or occurring in these regions. Monitor weather conditions..Listen for updated statements.

Details

A nearly stationary frontal system situated through north Central Vancouver island this evening will bring strong southeast winds of 50 to 80 km/h over many south coast locations this evening. Winds will ease overnight. In addition this system will continue to bring heavy rainfall to the south coast tonight. Rainfall amounts of 30 to 50 mm have already fallen across most of the Lower Mainland and East Vancouver Island with the heaviest amounts near the mountains. A further 25 to 40 mm are likely as another wave moves off the pacific overnight. Over west and inner Vancouver Island amounts of 50 to 80 mm have already fallen and an additional 60 mm are likely through tonight. The heavy rainfall will ease Tuesday morning.

Don't expect this thaw to last too long. The Siberian Express could very well reestablish itself late next week though early or mid February.

The Polar Vortex will retreat now. But not for long. This thaw should last a week(a week and a half at the most). Then The Greenland Block will restrengthen. Resume it's onslaught of potentially even colder weather!

But in the meantime, let the Pineapple Express show us what it's made of!


Here in S. Ontario, we've had a day in January or late December reach above 10C for the past several years now. In the winter of 2008-2009 and 2007-2008, the warmest day was around 15C, and occured in late December and early January respectively. Since we haven't had a mid-winter thaw this year after our first major storm in early January (usually this happens in November or December, so this is unusual), I expect some deep thaws throughout the rest of this winter, but they are not likely to last very long. However, if the low pressure system carrying the warmth ahead of its cold front stalls in place due to a blocking high, then we could have a prolonged period of warmth for S. Ontario and the East coast of the US, accompanied by rain. If we get more strong storms over North America, we could see snowsqualls, thunderstorms, and everything in between. However, a rapid temperature drop could occur at any moment. I remember in late March of 2003, the temperature rose to 28C, only to drop to freezing the next day. So while erratic weather is nothing unusual for Canada, we could see more than is usual this winter.

The Gulf Stream appears to abruptly weaken just north of Cape Hatteras, then its course is replaced by warm and cold eddies, then south of Newfoundland it partially diverts north and northwest toward Western Greenland.



The >8C waters off Norway have expanded farther northeast, and the Humboldt Current is resurging while the equatorial waters off the coast of S. America are cooling. However, the >31C pool in the Central Pacific ENSO pool is expanding and heading southeast, signifiying a strong Modoki El Nino. Also, warm water has expanded toward the Antarctic Peninsula from the Southern tip of South America.

While the Arctic Osciallation weakens and a strong warming trend sets up for North America in late January, the modified abnormal El Nino pattern will continue to progress. Global ocean current patterns will be affected by the path and intensity of storms, and I think we will still get many unusual surprises in the weather for the next six months as different parts of the El Nino cycle strengthen and weaken simultaneously.

Heck these same systems may very well bury the Mid-Atlantic/Northeast/Piedmont under copious amounts of snow! They don't have much of a warm-up(compared to the Plains which'll get back to normal-At last for a short bit before the next onslaught).

Noughties bring driest decade on record to Melbourne

* From: AAP
* January 12, 2010 12:09PM

IT'S official. The first decade of the century was Melbourne's driest on record.

Victorian Water Minister Tim Holding today confirmed that less runoff flowed into Melbourne's dams between 2000 and 2009 than any other decade in recorded history.

"What we've seen is we've had the lowest inflows into Melbourne storages in the history of our system, over the last 10 years," he said.

In the past decade, 3911 billion litres of water flowed into Melbourne's four major dams, compared with the previous record low of 5033 billion litres in the 1980s.

But Melbourne was spared from running out of water thanks to the conservation efforts of households and industry.

Mr Holding said water use per capita decreased by almost 40 per cent at the end of the decade, compared to the 1990s.

He said Melburnians used 357 billion litres of water last year, the lowest in decades.

"Our city has expanded by more than 700,000 people over the last 10 years but we are using hundreds of billions of litres of water less over the course of the last decade that we've used in the previous decade," he said.

Melbourne Water managing director Rob Skinner said not only had there been less rainfall over the past 10 years but the proportion of runoff into dams had also reduced because of the drought.

"The actual runoff into the reservoirs has gone down by 20 per cent," he said.

"So it's less rain - a climate change effect - but the effect on the catchments is a drying and much less water."

Melbourne's dams are 37.1 per cent full.
