WHAT: FEBRUARY MEGA STORM? START: 9 AM FRIDAY START PHL AREA11 AM NYC1PM BOSTON
END: 7AM PHILLY4 PM NYC 7 PM BOSTON (SATURDAY)
So we look at a storm which is about 2-3 days away and start to wonder...is this the BIG ONE this winter? For some it very well may be as the Euro plays a pretty decent storm (12"+ of snow) with wind.
So after looking over the models here is the raw data just in...
CITY EURO (SNOW TOTALS ARE WITH MIX)
BOSTON 34" (ALL SNOW) PROVIDENCE 31" (90% SNOW...MAY MIX A LITTLE)
PORTLAND ME 23" (ALL SNOW HARTFORD 20" (ALL SNOW)
NYC METRO 8-12" (SOME MIX LIKELY)
HUDSON VALLEY 12" (ALL SNOW)
CAPTIAL DISTRICT 10-12" (ALL SNOW)
SPRINGFIELD MA 10-15" (ALL SNOW)
LONG ISLAND (ISP) 8-12" (MIXING IN MID STORM)
MORRISTOWN NJ 7-9" (A LITTLE MIXING)
NEWARK NJ 8-10" (A LITTLE MIXING)
TRENTON NJ 4-6" (MIX TO START) ALLENTOWN 3-5" (LITTLE MIX)
It is interesting that this is occurring at the same time the Nao is tanking, I am thinking this component may very well be the staller mechanism not yet realized.
As your friendly Connecticut snow-hating meteorologist, I must say: what meteorologist who calls himself a professional would deny that this one's the real deal??!
It's a snow bomb mostly for eastern and northern New England, NW Jersey and upstate NY.
There will be a period of a wintry mix or sleet around NYC, Long Island, southern/central NJ, and southwest toward Philly and Balto during Friday as 850 mb temps warm up temporarily. As the storm bombs and pulls twd the northeast Friday evening, NYC and LI will revert to snow for the balance.
I'm still skeptical about going as high as 2.5 to 3 feet of white stuff for the top amounts given the storm's speed of exit and lack of strong blocking North Atlantic ridge.
Okay...let's watch this baby unfold and have fun! :)
We always or at least usually culminate with a big system after a weeks worth of unsettled small events.
I still would have thought we would get a culminator that would come from a cold hearted clipper (that would be already a cold cored entity) from a cold sourced region.
Take a cold cored clipper and bomb it off Va, and we are in the game. The NAO is declining for a reason, but our best nao readings for a coastal and snowstorm around here is a -1.0 nao reading.
The funny thing happens with these type of systems is that they enhance rotational entities around them. It could be that the low can enhance the high to the north. If i can recollect here that high in lastnihjts run wasnt that big it was small and the models were warmer because of it. Now that the models have pickd up on the teleconnetivs better and the influences in between them that why the models have trended colder.
Tim, I'm in Chester County and I feel your pain. It seems more often than not around here the cold air departs just as a ton of precip is ushered in with a big storm.
Wish I could say the same nkay, I am in delco just outside philly and we are getting nothing here. so take whatever you get even if it might be a 4-8 event which could still very well happen.
