Those couple of days we had around New Years's where it got well up into the 50's killed the snow pack. As many have said yesterday, mid 30's and moderate rain is not going to kill the snowpack, just add's to the moisture content and potential flood bomb. In any event, I really like the long range. Obviously their is alot of time to go but it looks like we will have another long wave trough to work with.

Welcome to winter on the I-95 corridor. It is rare, if not impossible, to have constant snowstorms without a warmup and a cutter that takes all the snow.

Even 95-96 we had a cutter a few days after the Blizzard. If you are looking for no cutters, you will have ti live out west somewhere.

the wavelength of the trof is smaller this run, but it's disorganized.. and very weak surface pressures pretty much everywhere.. there is nothing here that can really bring the surface pressure down.

Looks like basically a non-event here, maybe 1" snow, a bit of ZR, and then over to rain.

I'm a substitute teacher so I'm wondering if school might be delayed or closed. Probably not going to be enough this run...

essentially, what this solution amounts to is brief light snow.. dusting to an inch... High pressure wants to let go pretty quickly. I'm not sure I'd buy into it completely with the airmass in place, especially near the surface.. I'd think there would still be some icing in the valleys, but GFS suggest warm enough for rain fairly quickly and then showery conditions until cold frontal passaege

Everyone basically get's an inch of rain out of this run and it's basically a non-event since it won't be enough to cause flooding and very little QPF would fall below freezing.

seems like alot of QFP for such a disorganized storm--is there even a cutter on this run or just the low off the coast?

The flow is too progressive... the first wave dies off, but a new stronger wave dives out of the upper midwest, while the southern wave continues along.. light QPF

Brutally cold over Canada on the GFS, -40C 850s consistently showing up over the Northwest Territories under a 474dm PV.

Looks like a -NAO redeveloping with a 1032mb warm high over the North Atlantic...>0C 850s approaching Greenland at 144 hours. Double block for us. :thumbsup:

How is the flow too progressive with a +PNA and a +NAO? I thought it wouldn't be that progressive with those two being positive?

yep... there it goes... coastal bombing out off the coast of Boston... Major cyclonic vorticiity advection.. probably a heavy burst of snow with these dynamics.

Looks like a Manitoba Mauler type system as the 0z ECM advertised...great set-up with a 570dm ridge over the North Atlantic. Going to be crazy cold after that storm:
