ORH_wxman Posted February 3, 2022 Share Posted February 3, 2022 Some of these mesos at 12z are obscenely frigid tomorrow AM. This is going to be an interesting nowcast....because while model bias may be to cool the midlevels too quick, the surface/BL is a different story. The typical bias on model guidance is to cool too slowly when you have a meso-low out east....particularly if a weak barrier jet forms over SW ME and SE NH and then that will just rip right down the corridor east of ORH hills. 5 Link to comment Share on other sites More sharing options...
WinterWolf Posted February 3, 2022 Share Posted February 3, 2022 Mentioned this yesterday, but the modeling disagreement with this, and this year is astounding. Never a consensus this season. WTF? Link to comment Share on other sites More sharing options...

das Posted February 3, 2022 Share Posted February 3, 2022 A little nowcast obs from up here in NW VT. 36ºF with light showers. The cold press is certainly delayed. Just now seeing the first evidence of it crossing the border. This is 2+ hours behind hi-rez guidance, which had already delayed it 4-6 hours starting last night. 5 1 Link to comment Share on other sites More sharing options...

Yeah some mesos have that and others do not. I guess it comes down to whether or not a weak low forms near the Cape. Link to comment Share on other sites More sharing options...
PhineasC Posted February 3, 2022 Share Posted February 3, 2022 NAM and high-res guidance is all 1.7"-ish liquid or more. 3k NAM and FV3 would be 20"+ here at 10:1. The band of Friday afternoon and evening looks more and more like high-ratio fluff here; that could tack on 5" in a hurry as the system departs.

Spaizzo Posted February 3, 2022 Share Posted February 3, 2022 37/38 going back and forth down here in the Naugatuck Valley. 40s all around just tossing it out there’s not expecting much but was expecting it to be warmer by now here (Ansonia) Link to comment Share on other sites More sharing options...
PhineasC Posted February 3, 2022 Share Posted February 3, 2022 I haven't seen any updates from the 30" blizzard zone. How is the pack holding up so far there? Curious if some can survive this event. 1 Link to comment Share on other sites More sharing options...
Sey-Mour Snow Posted February 3, 2022 Share Posted February 3, 2022 Euro dominating the cold push , 10am rtma vs fv3 which is the coldest model and euro at 10am. Link to comment Share on other sites More sharing options...

GFS was actually pretty good near PIT this morning (had to forecast there last night). GFS was a couple degrees too warm but showed the arrival of 32F better than hrrr. Doesnt mean it right here though. Link to comment Share on other sites More sharing options...

I've noticed over the past couple years some of the HREF members tend to be a bit too cold at 2m and can over-do the low level drain down the valleys here in CT. But it is definitely interesting seeing the 12z HREF mean solidly below freezing in Hartford at 12z while HRRR/3km NAM (which are both HREF members) much slower. Shows you how frigid those other members are. I'm hoping by later today we have a better sense of where that weak wave forms to our southwest and where the front sets up. 1 Link to comment Share on other sites More sharing options...

There was less disagreement there than there than here. Tough and interesting call around here. If we do get a meso going and solid NE flow, it may very well tuck better into E MA than further west, atleast initially. 3 Link to comment Share on other sites More sharing options...
klw Posted February 3, 2022 Share Posted February 3, 2022 light snow mixing in here in downtown Burlington (BTV), most of the pack is toast here but survived without much of a dent at home. 1 Link to comment Share on other sites More sharing options...
