March 4 - 6" March 9 - 3" March 14 - 9" total - 18" Not in DC, they mostly missed the first and 3rd events, they had the one in the middle and that just about it other then a sloppy inch or two with the March 14th. I was not talking about our area, we do much better. Our WORST years usually still manage to get up into the 8-12" range while that is actually just a typically crappy year but not historically bad year in DC or Baltimore. Their duds are under 5" years. Link to comment Share on other sites More sharing options...

Those areas are colder at 850 mb and surface(as modeled) due to elevation and dynamical cooling most likely. And that is what it would take for a storm with a crappy air mass to produce snow- elevation and dynamics. It would need to deepen faster, or any ccb snow will be northeast of the MA. That is more likely. Most likely its a cold rain for this entire region, but there is an outside chance at some snow for the mountains. Link to comment Share on other sites More sharing options...

PaEasternWX Posted January 19, 2017 Share Posted January 19, 2017 Literally the euro would only need to be 5 degrees colder in all levels and it be a wet paste bomb for 1-95. It is so close. Not bad for 100 hours out. Keep it trending 20 more miles until the event and then we got something. Link to comment Share on other sites More sharing options...

psuhoffman Posted January 19, 2017 Share Posted January 19, 2017 The bickering is pointless. The early week period has trended a lot colder the last 72 hours. That is undeniable. Its now very close for places up here and out west. 1-2 more degrees and were looking at a wet snow paste job. It still needs a bit more work then that for the Dc/Balt area. The models right now as they are still show mostly rain up here and all rain in the cities. Has there been a trend colder yes. Arguing the details of all that seems pointless. But the cold isnt "coming" from anywhere, the models are simply trending colder with the entire column, the cold is simply appearing over us so to speak. Part of that is the storm evolution becoming more favorable. Placing the H5 low and CCB over us which then aids in convective cooling. get the low a little deeper and heights to crash just a tad bit more and its possible it trends a little colder. Still a tall order. But for some with a little elevation NW of 95 its close enough. I don't usually post about stuff like that because if your in DC you dont care. But location matters so to pick on someone up here or out by winchester who has a slim chance of something out of this just because you might be in a location that doesnt is petty too. As mitch pointed out its still 100 hours out and has time to continue to trend better or pull a lucy on us. Link to comment Share on other sites More sharing options...

I think part of the "cold" stuff is the fact that it is the heart of winter and cold is pretty much the baseline. It's pretty easy to get to "cold" even in an above avg temp setup.

aldie 22 Posted January 19, 2017 Share Posted January 19, 2017 Remember that storm in the 2000' when it snowed in Louisiana and Alabama from a bombing low that created a cold air bubble while everyone else was hot.

Trend toward colder air for those of us along 95? Where's that air coming from? The trend towards colder the last few days isnt because the cold is coming from anywhere. Its more that the models are trending the entire airmass a bit colder as we move closer. Some of the recent colder look is due to a shift towards a more consolidated well organized system with a perfect H5 pass. That places the ccb over us along with the crashing heights under the H5 low and combined leads to enough convective cooling to get us close. To get the last 1-2 degree drop I would need, or 4-5 you would is going to be tough though. We are already talking about a pretty perfect track here so not much can improve there. We would need a slightly more amplified system perhaps. Or simple model error, like they are too warm by a couple degrees, that is not crazy. The low is pretty strong but not maxed out in potential so a slightly stronger system is possible. NOT likely but possible. The models could be underestimating the cooling, a bit more high pressure building up to the north under the ridging, a bit more convective cooling....eehh do I think its likely NO but within the realm of possibility yes.

H2O Posted January 19, 2017 Share Posted January 19, 2017 It is just as fair to say the models can't be right with warm temps shown 7+ days out as it is to say they can't be right about the cold temps. Here's the thing. this winter our "warm' spells have often been muted and not as torchy. i'm less likely to believe that temps will be as warm as shown that far out. And that we are in the colder part of our winter climo tells me that it is something to keep an eye on. And since a majority of our classic snows have temp issues it wouldn't be surprising for I-81 to get pummeled and me get rain and 32.1F Link to comment Share on other sites More sharing options...
