The Northeast Weather Blog...

A taste of winter...
Posted by: Zachary Labe, 1:06 PM GMT on October 12, 2012 +2
Good morning and happy Friday! It is another terribly dreary day here across the Finger Lakes as some light CAA rain showers move across New England ahead of an approaching cold front. Frost and freeze products have been issued for the entire Northeast and as far south as northern Virginia. A ridge of a high pressure behind the trough will create ideal radiational cooling conditions Friday night as temperatures drop at or below 32F for most climatological reporting stations. This will bring an official end of the growing season to the viewing area.

Looking at the climatological first frost dates, this year's freeze conditions are right around normal for areas along and north of I-80, but running even a few weeks early for areas to the south. Interestingly enough, last year's first 32F weather corresponded with the anomalous snowstorm around Halloween. This year is a bit different.

A lot of people have begun to ask me about the forecast for the coming winter. After last year's record warmth and low snow levels, many are left wondering how this winter will compare. With great certainty I can conclude that this winter will be colder and snowier than last year, but in reality that is not very to do. While I am waiting another two weeks or so for my official winter forecast, I will take a quick look today at some of the features in question.

The major player in forecasting long term weather during the winter months generally revolves around the condition of the ENSO. CFS prognostics for Nino region 3.4 SSTs continue to indicate weak to moderate El Nino conditions forming by early to mid winter, but taking a look at the actual pressure and SST anomalies in the equitorial Pacific show a different story.

The latest SOI numbers coming in indicate a bit of cooling for September and October supporting the idea of neutral to weak El Nino conditions this winter. Current GOA SST anomalies are more indicative of the previous La Nina with cooler water temperatures and a stubborn -PDO. There has been a bit of improvement in this region over the last few days and weeks, but concerns over the formation of the Alaskan vortex are beginning to grow.

None the less as rossby wavelengths become shorter, teleconnections will play a larger impact on the synoptic weather patterns across the CONUS. Nearly 12+ months have been dominated by anomalous warmth across the Northeast, but we are beginning to see the pattern break down. A strong -EPO is responsible for this recent surge in cold weather across the Midwest and East. As noted in the SST's above, this animation Link shows great improvement in the breaking down of the bold -PDO across the north Pacific.

The El Nino is also not dead. Long range ensembles indicate weakening easterly winds at 10mb in response to a westerly wind burst that is in the forecast grids during the next few weeks. This may help to restore weak El Nino conditions to Nino region 3.4.

The MJO is beginning to yield outside of the 'circle of death' as we begin to see an increase in monsoonal rain patterns over the Indian Ocean. This will impact long waves and the current ENSO.

Outside the equitorial Pacific, other factors including Siberian snowfall departures indicate a pretty substantial snow cover thus far this year. While still below climatological norms, snow cover is at or slightly more widespread than the past few Octobers. Snow cover though is lacking in Canada, but the correlation is much weaker between Canadian snow cover and weather patterns over the Northeast.

Above is a brief look at the status of the major indices critical to forecasting long term weather patterns. But what does it mean for us? I think we can expect a general weak El Nino presense, although its impact will be even more subdued due to the Nina-like -PDO. There are signs of a stratospheric warming event as we enter November and December, therefore possibly signaling colder and snowier weather in this time frame. In fact long term wavelengths are supporting some type of winter storm around this time next month. This could time nicely with an influx of colder air that is currently being sniffed out by long range guidance in early November. It is likely early November will feature a higher than normal chance of a widespread snow over the Northeast. Given the current state of the stratosphere, there are also higher odds that winter will start off colder in December. Based on current teleconnections and analogs, I am leaning towards a near normal temperature winter with slightly above normal snowfall for most areas. The major concern in the coming weeks will be the status of any formation of the Alaskan Vortex. This feature killed off most all snow chances last winter. While it does not mean anything at this point, the entire synoptic flow over the globe is entirely different than last year at this time.

This blog will hopefully kick off my once-a-week blogs starting from now through winter. I will have my official winter forecast posted around Halloween.

Thanks Blizz for taking the time to post these blogs, I know you are busy. I know that part of NY State can be dreary. I went to Grad. school at Suny Binghamton in the mid 1970's, and at times it was a big "event" to see the sun.

I can't wait till the snow starts falling. At least this year I won't have to buy oil since my pellet stove is being installed Monday. Thanks for the blog Zack. I been following u for about four years now and my mom always ask what are you saying about the snow.

John LaCorte has a great article about the arctic and antarctic ice sheets in the fall 2012 edition of SKYWARN news from the NWS in State College. Of course there are other very interesting articles too but I thought LaCorte's was particularly relative to the conversation we were having in the previous blog about the article that TRP posted.

34F, Light Frost, Tinton Falls NJ

Good Morning. Nice crisp morning for exercise. Crystal clear. Moon the slightest of a sliver. Light frost on the grass but it is widespread. A moderate frost on the cars and rooftops.

We shall see if the remaining parsley and stringbean plants can survive to be picked.

Regardless, the cold tells the plants to shut it down and growth slows.

Seems like as the morning progresses the frost continues to thicken on the neighbors lawn some more.

A hard freeze here in the LSV, Blizz. My low this morning was 29.3F

Thanks for another great blog, Blizz.

I think this is the earliest freeze we have had in at least 5 years, probably more. It seems to me to be more normal, though. Hopefully, the pesty bugs were killed. I know the past couple of weeks the stink bugs have been all over the house looking for ways to get in the house.

I picked all my tomatoes and peppers yesterday. I still have some carrots in the ground. They should be ok, I think.

TRP you are correct in your assumption that this "feels" right. It does...going back several decades even - I recall this being normal.

What we can draw from this is anyone's guess. I'd love to say this means a "feels right" winter in that we are threatened with weeks of temperatures flirting with zero degrees in January, with the day and a half that stays in the negative single digits, and several big storms, but I just do not know if that's possible or prudent to draw any correlation.

I like what I see though... and so far both September and October, both slated to be above to much above normal temp wise by the CPC's longer range outlooks, have been cooler to much cooler than normal.

I like the trend. No Indian Summer. Low 70s Sun-Mon and then right back into the 60s.

Very nice trend. It's been a long time coming!

And yes, the cold did it, the stringbean plants are half fallen over this morning with curled leaves. Going out there to pick the odd dozen somewhat juvenile beans off of each plant and then turn the garden over.

23F looks to be the low this morning here on campus with a hard freeze. Fall foliage will be peaking up here in the Lake Cayuga area probably within the next four days.

That idiotic Middletown weather station missed their record low by 1F this morning and was nearly 3-5F warmer than surrounding areas; what a joke. Nevertheless many records lows fell this morning and in some areas this is the earliest records 20s since 1993.

Do you have any idea where KMDT's ASOS is in relation to the Susquehanna River? The image on Google Earth is a bit too blurry to clearly discern it.

KCXY, which is about 4 miles away from KMDT, reported a temperature 2F lower.

My theory is that the much warmer Susquehanna River gave them the extra couple degrees.

Meh, haha, I have had ongoing complaints about KMDT since I have been little. Their precipitation, snowfall, and temperature data is always way off compared to surrounding areas. While it could be the river, I think there is another explanation. Even the one time when I visited CTP NWS, they mentioned that KMDT may have some equipment that is faulty.

Low here in Stamford CT. this morning was 30.3F. Still have my 50 plus years old grapefruit plant outside. I think I will keep it out another week or two. Don't see any sub freezing temps. for awhile. It does much better outside than in.

Nice, LT. First below freezing?


Well...it seems tonight's forecasted lows are going to be off.

We are forecast for 47. It's already 46 at 730PM and dropping steadily.

Early to bottom out given tomorrows 72F?

My vegetable plants were killed, except the carrots. Even the marigold leaves look dead. They were blooming so well.

Blizz:

It has been a while since I posted on your blog, but I have been looking at it quite often. I am sure School is keeping you busy and adding to you knowledge.

I know you are busy, but was woundering if you could possibly help me out.

I have been working on Geneolgy in my family and have a brick wall that I have been trying to break for about 30 years, and oncerns my Paternal Grandfather.

The story I have heard from several of my relatives is that Fred Dayton was born about October 4, 1885 in Cooperstown, NY. This is what he has as his birth on all of the documents that I can find. However in checking in Cooperstown, I am unable to find such a birth certicate.

The story has it that about 1889, when he was three or four years old, his parents were killed in a flood. As a result of the death of his parents, he was placed in an orphange in New York State. Possible Cooperstown or Rome, NY. I also checked orphange records and was unable to find any conclusive records.

Here is where I am asking for your help. In May of 1889 we have all heard of the Johnstown, PA flood and it is my understanding that the same storm that caused the Johnstown Flood also caused a lot of floods in New York State. They also had another Flood in 1889 which appears to be caused by a early winter thaw that flooded Buffalo, NY in January of 1889.

What I am trying to find is a data base, or articles that will provide me with a list of floods that have occured in NY around 1889 and/or also that shows the rainfall amounts.

I have checked a lot of County and Local Histories, but they don't seem to have much information on flooding that occured. If I can find some dates and places, than I may be able to check out archived newspapers to find additional informaton.

If you don't have time with your busy schedule, I will understand.

Not as cold in Harrisburg this morning as it was yesterday. Some plants were able to survive, but I don't expect to get many more crops.

Morning all. Relatively warm and humid and breezy - overnight low of 63F.

Not impressed with today's radar imagery - I would suspect scattered light showers are most likely for us later this afternoon.

Couldn't rule out a little warmth energizing the front - and perhaps we get one of those weak narrow squalls.. the low topped moderate rain types.

Nothing exciting - except to drop us back into the 60s/40s splits we've been treated with.

Thanks Blizz. Right now I am concentrating on the area around Cooperstown, NY and the surounding Counties, which are just to the East of Ithaca. Probably the same major floods they had there would help as the areas are about 100 miles apart.

Thanks again

With the morning wearing on the radar to the SW is starting to fill in quite a bit over VA...with some building showers into MD and PA.

With the strong SW flow it *appears* this activity has a chance to overspread NJ and get into possibly CT if it comes soon enough.

The breezy conditions have become more of that familiar turblent breezy pre-frontal weather we have been experiencing around here since September.

Nice breakdown, Blizz. First freeze of the season was had up here in Huntingdon on Friday night. I was out and about at 3:30 AM Saturday morning and the thermometer in my Blazer read 25 degrees. Certainly nice to finally feel a chill in the air here.

Foliage up here looks ok, but in some spots it went from being green to dead pretty fast. The view from outside my window shows a lot of past-peak foliage, which I guess is normal for this time. Just didn't seem to be at peak stage very long. Unless I'm way off.

That's it from here. I think lol.

Haven't been around in a while,busy,busy,busy,but always start to get interested in the blogs as winter is just around the corner.I sense the mid-atlantic may get the brunt of the snow,but we all should do better than last year,certainly hard to believe we could get less.

Looks as if a decent disturbance formed along the front and moved into Eastern PA --- unfortunately this development robs energy from the portion of the front that will slide through Southern and Central NJ - so other than some steady showers - mostly light or perhaps moderate here or there - it's not going to be a big event.



5-day QPF has 3.5 inches of rain widespread through NJ and Eastern PA. I have no idea what that is about.

Changing of the leaves has accelerated here finally. Most everything has a yellowish or reddish hue to it now. Other than the Autumn Flame Maples...nothing is displaying vibrant color - although our red maples have a couple of leaves that are quite brilliant so there is some hope there.

It has just been so long since our Foliage has given the appearance of everything being on fire so to speak. Just so many failed seasons - either washed out colors - or gone green right to brown -etc.

Geez just look at that disturbance steal focus of energy away from my area...everywhere south and east of I95 is bust.

I might not even get more than some quick light showers.

Disappointing. Certainly not according to plan, forecasting, nor modeling.

Blizz, thanks for the early update.

We had our killing frost last weekend... and then the warm balmy days this week. But by our non-scientific standards, in my neck of the sticks of NJ... the Oak Trees have produced an abundance of acorns (head hurtin' poppers), as opposed to nothing last year. Any fruit on apple trees are dropping fast... and deer are nibbling more than ever closer to residential developments. Old timers say we will have a good winter snow by Thanksgiving! But they don't think it will be as cold as it should be.
So much depends on a good cold and snowy winter...

Let's see what happens.

Total rainfall for my area, Stamford CT. was, 0.38". Also here, this year again, like last year, our "acorn crop" is very tiny, almost non existent, after two years of "bumper crops". The years of bumper crops correlated with the 2 good snowy years. We'll see.

I received 0.38" of rain yesterday.

I just planted a few trees and hope we can get rain like that every 4 or 5 days. I planted a White Oak, Sugar Maple and Gingko as well as 2 Douglas Firs to replace the 2 I have lost the past year. I planted a Red Oak and White Oak a couple of years ago and they are doing well. I love Oak trees. I grew up in a residential area that had a nickname of the Oaks, since all the streets were named after a different Oak tree. It's a shame more people don't plant more Oak trees. Way too many Maples. Maples don't provide for the critters in the wild.

Truly amazing that the acorn crop can be so different a couple hundred miles apart in a relatively similar climate. From the last two posts.

Is there a plate there? Would it be similar to the Earthquake that hit the East Coast in 2000 or 2001 or 2002? I was in Chester, NY (60 miles NW of NYC) for that one and laying in bed that morning. It felt like the washing machine was off balance, how it shakes the floor.
