DISCUSSION:

Winter Storm Watch:  Friday AM – Saturday Afternoon for Hampshire, Franklin County, & Northern Berkshire County.

Good Thursday morning I’m 22News Storm Team Meteorologist Nick Bannin. We’re expecting another quiet weather day today with brighter skies and highs near 50 degrees this afternoon. While I expect mostly sunny skies, we’ll notice clouds increasing late this afternoon.

Tonight skies turn cloudy, but the weather should be dry for the evening and most of the night.

As we head through the early to mid-morning Friday flurries and light snow arrives, becoming widespread between mid and late morning. Snow will turn to a wintry mix of snow, sleet and possibly some rain during the afternoon and will continue as a wintry mix Friday night with the addition of some freezing rain possible.

The wintry mix of weather keeps going through Saturday morning, but then drier weather moves in for Saturday afternoon and the rest of the weekend.

This will be a heavy, wet snow with sleet and possibly some ice mixed in. Temperatures during the day on Friday will likely get several degrees above freezing, especially in the lower Pioneer Valley, which will help with snow removal efforts. As temperatures drop Friday night we’ll likely see conditions deteriorating as temperatures get colder.

This is an incredibly complicated storm system, because temperatures won’t be THAT cold. This means that subtle differences in temperatures at the surface and higher in the atmosphere will play a MAJOR role in determining precipitation type and accumulation amounts. Prepare for accumulating snow and sleet on Friday into Saturday morning, but be aware that our snow/sleet accumulation forecast will likely be adjusted between now and the first flakes and possibly during the storm as our confidence increases.

Here’s our initial snow/sleet accumulation forecast. 

I’ll work through the timing of this wintry mix of weather on 22News 4:30-7AM.
