I’m not as bullish for here, Maybe 1-2” right now, The rest of that map seems ok.

3-4" would be nice, though the RA portion might turn our driveway into an ice palace.  We're in the zone where 10 miles west or east would make a big difference in the GYX forecast percentages: Farmington's for 4"/6" are 59%/27% while at Skowhegan they're 27%/3%.  Our place is about 6 miles from the former and 15 from the latter.  Could go either way.

Almost looks like a bit of dynamic cooling going on with the NAM

It's there on all guidance....starts off pretty dry in Mid-levels with this polar airmass in place prior to the precip so even though the high is retreating, there may be a few hours of steady snow as evap/dynamical cooling work in tandem to offset the WAA for a time. You want that good burst of precip though....won't be much snow if you don't get a couple hours of good precip rates.

NAM has a little cross hair sig in that 495/pike region too, so if that is real, that would help with latent cooling. Good snow growth will latently cool more efficiently than crappy ice crystals falling into a warm layer in the BL.

Yeah that’s a cross sig there on the initial burst. It’s been slowly cooling with that stuff.

3k NAM was similar too...sometimes it doesn't agree with 12km, but it does on the 12z run. Will be interesting to see if RGEM agrees too...if it does, then that would be a lot of mesos (if we throw in HRRR) agreeing with accumulating snow in that ORH to FIT to 495 corridor.

yeah I was looking at ORH on bufkit and that's a pretty decent cross hair signature. 6z NAM had 20 units of omega into the DGZ. You can really see the warm air is really struggling to penetrate into the polar airmass. Giving timing of precip too this could be a nice burst of accumulating snow for the interior.

RGEM not quite as enthusiastic....more limited to N ORH county...esp Rt 2 elevated region.
