2/13-2/19 Potential To Make NYC Coldest Weeks Of 2000's List


bluewave

Recommended Posts

Unlike the two Arctic outbreaks at the beginning of the month, the next two Arctic outbreaks

look like they wont have a warm up between them. This could possibly result in one of

the coldest 7 day stretches for our area of the 2000's so far.While  It's too early to determine

what the exact ranking will be, temperatures might average below 20 degrees for the coldest

7 day stretch during the multiple outbreaks. This would also result in a greater ice build up

on our local bays than we experienced earlier in the month. I compiled the coldest weeks

in NYC since 1960 with the 2000's coldest weeks highlighted.

Have Erie and Ontario frozen over yet? Is this cold coming in with wind? Hmmmm, might be pretty good ski conditions in the favored areas. Road trip?

 

Lake Erie still has some open water but it will likely freeze during this next cold period. Lake Ontario is too deep to freeze outside of the shallower areas near the shoreline.

The GFS and Euro have backed off a bit from the extreme cold that they were showing at 12z yesterday in the long range. We still sit at -20 to -24C 850mb temps for a few days but the -40C 850mb temps that were shown into the upper mid-west stay up into Canada on the latest modeling. It's all going to come down to the orientation of the polar vortex.

As much as I love extreme cold, ice in the rivers, etc. (yup, I'm deranged :lol: ), we don't want the core of the Polar Vortex to come down too far south if we want better shots at significant snow events and avoid suppression. Best case for most of us would be for it to hover to our NNW a bit and eventually elongate to the east and west of the actual core.

Makes sense.  What they were showing was almost unheard of.

I believe January 96 occurred as the PV was pulling out of the area. I could be wrong (I was only 10 years old at the time). That can be a really ideal situation for a major system and some of the long range modeling has been hinting at that possibility. Of course with any PV you can also get suppression. The 00z GFS almost brought the edge of the PV into northern Florida with the 850mb freezing line making it down to Orlando with much of northern Florida below freezing at hour 150 at the surface. That would be extreme cold, but not historic. It's the kind of rare setup that can bring snow chances to the sunshine state.

Is there a record for NYC for the number of consecutive days in a row that the minimum daily low always was below freezing?

January 1996 was a picture perfect scenario and the vortex was retreating a bit. We had a perfect -NAO, -EPO connected up to the AO and a spectacular +PNA orientation and the ideal 50/50. The beauty at 500, 700 and 850 makes me cry lol:

What about a maximum of 32 or less(consecutive days) I know 01/19/61---02/05/61 of 16 days[just a high of 31!), any others? Check a newsreel of Kennedy's Inaguration near start of this period and everyone looks like they are freezing there!

It doesn't get much better than a closed off 850mb low over the Ohio valley with perfect moisture transport from the ocean and an abundant cold air source. We'll probably never see anything quite like that in our lifetimes again.

At one point during the storm while living in my hometown of Howell, NJ I had 11 degress and whiteout conditions lol.

Oh the good ole days, back when the Weather Channel was actually watchable and had great experts like Paul Kocin. It was one of the rare times in my life where we had back to back snow days. TV mets were also a little less conservative in those days. It was before the March 2001 debacle and when a majority of the public, outside of mets, knew even less about weather forecasting. The internet has changed things dramatically. I would give up snow for the next five years for just one 96 redux.  

 

Boxing Day was exciting but my totals were about half of 96 thanks to the best banding staying just to my east. The most impressive feature of that storm for me was the winds.

 

I was in Daytona Beach for PDII. I remember being very upset about it.

96 was incredible.  Back in the Shenandoah Valley, we got 3-4 feet of snow.

And to think the GFS (or I guess AVN back then) was still suppressed up until the Friday night before. Forecast was for light snow Sunday night into Monday and we were less than 48 hours from a blizzard.

Agree with you about Boxing Day, 1996 was better from my perspective though I am the one who got the Boxing Day banding you speak of lol. Don't feel too bad about PD2, I missed it also as I was in Las Vegas lol. By the way, President's Day that year came out exactly the same way it comes out this year with Valentine's Day on a Friday.

Yeah, that March 4-6, 2001, "Greatest SnowStorm that Never Happened" was covered by 1010 WINS as a live event days before its supposed beginning. 30" in 60hrs.!!! was AccuWeather's mantra. The tombstone reads [5.5" and still waiting].

This doesn't really surprise me. We all remember the modeling debacle that occurred with Boxing Day and I believe the GFS was still backing Sandy into Cape Cod less than 48 hours from landfall.

 

When you have strong subsidence the models seem to have a much easier time handling things. February 2010 comes to mind. That month broke a lot of hearts up this way, but boy was that epic for the mid-atlantic.

Even Sat morning, WINS was saying it would stay south of NYC...it wasn't until the mid-day runs that they came north-so we had 24 hrs notice roughly.  And even then they were all going 6-12 for NYC-that was Sat evening.

I'll never forget that storm. That was really the first time that you had such a major bust in the modern internet era. A lot of the more bullish forecasters changed their forecasting style after that. I remember watching the weather channel as with each consecutive update Paul Kocin pushed the 12"+ contour further and further north. My school was closed for two consecutive days and we barely saw advisory criteria totals.
