Tomorrow:  Some morning drizzle then cloudy skies but mainly dry, some areas of fog, milder. Highs: 38-44.

 

Good afternoon!

Clouds will continue to thicken up this afternoon as snow overspreads western Massachusetts later this afternoon and evening (4-6 PM).  The snow quickly becomes steady and sticks with temperatures in the lower and middle 20s as it falls. It will snow at a good clip for a few hours this afternoon before it changes over to sleet and freezing rain.  The precipitation will lighten up in intensity around midnight so we’re not expecting any major ice problems. We can expect a general 2-4″ of snow before the change over.

Any freezing drizzle or drizzle will end early tomorrow morning. In fact, most of tomorrow will dry with cloudy skies and areas of fog. Temperatures will inch into the upper 30s and lower 40s closer to more seasonable levels. This will lead to some melting snow and ice.

As an Arctic front behind the storm slowly slides through, an additional wave of low pressure will track along it and just to our south Thursday morning.  By then, temperatures will have cooled sufficiently to allow any precipitation to fall as snow.  The question is how much (if any) of the northern edge of the snow shield actually reaches western Massachusetts.  This is definitely a highly uncertain call as some of the data gives us yet another snowstorm Thursday while other data gives us nothing.  If we see snow it develops late Wednesday night or early Thursday morning and ends during the day.  Areas along and south of the Mass. Pike have the best chance of seeing Thursday snow.
