Hey, what's the start time for Pittsfield on the euro folks? There's an 80% chance of me chasing. Plenty of rooms at the Hilton Garden Inn and Fairfield Inn. Thanks.

 

 

They do just fine in westerly flow events, better than MPM, just ask Mitch. They do get screwed different ways but it's not always from downslope.

 

 

Unless the models trend considerably colder in the next 24 hours, I'd avoid this area during a SWFE type situation. Easterly flow in the low levels causes downslope around Pittsfield (and anywhere in the US 7 corridor really). The downslope flow frequently causes a modest precipitation shadow as the air warms and descends on the west slope. It's usually not major, but we may get 4-5" while the eastern slope gets 7-8". Of course, midlevel forcing can override terrain effects. In addition, the warming will often extend to the midlevels since the terrain induced gravity wave propagates upward, causing us to flip to sleet quicker than equivalent latitudes to the east when the thermal profiles are marginal. 

 

If chasing, I'd recommend booking a room near Greenfield and going from there into S VT or NH as they should stay colder and avoid the problems we typically have in this type of setup.

 

Early call is 2-4" and then sleet for Pittsfield area. I'd go 4-7" for MPM's area before sleet. N ORH up toward Essex County MA does best with 5-8". Things don't look too good for the south of the Pike crowd this go around with maybe an inch or two to about BDL latitude.

Still a significant difference In thermal profiles and the resulting snowfall amounts prior to the changeover between the Euro/CMC and the GFS for the northern part of CT. The area north of the Pike looks good for a nice 3-6,4-8 type event obviously favoring latitude and elevation for the high end amounts. My question is whether the BDL, CEF corridor is a C-2 or more of a 2-4 snowfall event, possibly even 3-5 if enough dynamic cooling of the column to offset the warming aloft and we get a few hours of of mod/ heavy snow before the taint.

I still think this could easily trend colder. When's the last time we saw a 1004mb low slam into a 1044mb high? I definitely expect a lot of CAD at surface and quite possibly colder 850s ahead of the storm...that high has -30C @850mb in Labrador, -20C in Maine...we should be a bit colder than the -1/-2 that's been depicted.

0z GFS also looked a bit colder and further south. Confluence tries to force a redeveloper, and 100 miles south in that confluence could turn this into a NYC (or DXR) north storm rather than BOS north as currently modeled...
