Weekend storm - Grasping for straws


Ian

Recommended Posts

Just some random thoughts here, but there are several indicators in my opinion that this will not be much of a storm for the Mid Atlantic and I-95 area below say NYC. First, the trough tries to turn negative on most of the models too late. And when it is turning negative, its only slightly. From what I have seen in the past, our big East Coast storms involve a strongly negative trough. Second, when is the last time anyone has seen clippers diving through Southern Virginia repeatedly during a winter recently? I dont recall it happening which would tend to tell me that the PV is stonger than average causing supression of any system that makes a run for the coast. Third, and this is more of a question than an opinion, but dont these storms usually follow the baroclinic zone between above and sub freezing temps? If thats the case, its been clear for days that this storm will be out to sea.

Different year, different pattern. What are you expecting this year? The same as last? Your ground is white right now, yes?

It was nice to see it snow but I felt sort of let down.. Back to normal I guess

yesterday was a gift. We weren't supposed to get much of anything initially. I still think that any call for 12"+ season total is bold so I'm of the opinion to bank anything we get now.

hey ill take any snow i can get but 1.5" that equals wet roads just isnt the same -- i'll probably hold onto the hangover this season i guess

As I posted in the ensembles thread...

ALL 18Z members get some snow up to DC. OP is the only one that does not!

3 Members are a bigger deal for DC... (P003, P005, N003)

All 18Z members seem to have decent snow for E VA including RIC.

It appears that many of the members aren't really suffering from the conv. feedback that the Op is suffering from, resulting in a more potent low.

Glad I don't have to make a forecast...and not sure what it all means if anything.

At this time range using the GFS ensembles is a big mistake as their low resolution will spread the precip out which is why they are hitting dc. You should be looking at the sref which have a much more bearish look as they have better resolution than the gfs ensembles. That said, the best ensembles now are the higher resolution versions that have higher skill: the eruo, gfs, ukmet, both canadian models and the nam.

Thanks for your insight. What amazes me is the diverity of solutions on the members (SREF and GFS) still for 36 hours. I guess though in most cases we aren't monitoring for a miniscule shift that means snow or no snow.

FWIW The 06z nam came west.. check out the 700 map

btw i noticed that none of the models are catching the precip currently over tenessee/kentucky.. infact they had it but they modeled it to dissipate before it even got to where it was..

Since we're grasping for straws, the eta5 panel (bottom center) is one of the few that picks up on any of that precip. It's also the one that gets the snow this far north.
