December Storm Midday Update

Despite GSD skepticism yesterday about how big this storm will end up being, local forecasters continue to raise our expected snow totals. Notably, NWS Albany thinks the entire county will get over a foot of snow, with some locations in the south getting closer to 18".

One really strong signal that it's going to snow--and snow hard--is that it's 15 degrees outside with complete cloud cover as of 10 AM Wednesday. Any moisture that overrides that cold air will become snow. Because it's so cold, a lot of that liquid will evaporate initially, but then by about 7 or 8 PM, the snow will starting making it to the ground in the Berkshires.

Just over a year ago we had a 36-hour event (in early December) that produced 16-24" in and around Berkshire County. While this storm will not last for 36 hours, it could certainly challenge those snow totals.

One other aspect of this storm that we failed to mention in earlier posts--beware of the wind. We're supposed to see wind gusts well into the 30 mph range in the overnight hours. Should those winds continue into the morning hours, travel will be very unsafe for the commute.

Get the tall boots out--we're all going to need them.
