Our stretch of mild weather is coming to an end and we are now facing our first winter weather event of the season. Skies will gradually clear out this evening as a cold ridge of high pressure builds in from Canada. Lows tonight will drop back into the lower 30s.
We will start out with sunshine tomorrow morning but clouds will increase as we go into the afternoon and evening as our storm system approaches from the southwest. Precipitation looks like it will hold off until after midnight Monday night but with the cold air in place it will start out as snow. As we head into Tuesday morning we will see snow changing over to a icy mix of sleet and freezing rain just in time for the Tuesday morning commute.
As we head into Tuesday afternoon warmer air will try to work into the region which means a change over from sleet and freezing rain to plain rain. The Tuesday evening commute will be a slow one but does not look like it should be impacted as much as the morning commute. A Winter Weather Advisory goes into effect Monday night at 8 pm and lasts until 1 pm Tuesday afternoon for Hampden, Hampshire and Franklin counties. The Winter Weather Advisory for the Berkshires goes into effect at 7 pm Monday night and lasts until 7 pm Tuesday evening.
Early thinking on snowfall total is 1-3" for the lower Pioneer Valley and 3-5" the for areas north of Northampton and the higher elevations. These snowfall amounts are subject to change depending on when the change over in precipitation type takes place. Stay tuned to Western Mass News on air and online for further updates.
