Rain and sleet is expected to continue for a few more hours before colder air on the backside of this storm turns the precipitation to all snow everywhere just before midnight tonight. The exception will be across the Berkshires and the northern Worcester Hills where snow will continue right through the rest of this evening.
During the after midnight hours of tonight, it is expected to snow at a light to occasionally moderate intensity across all of Western and Central Mass and this snow will persist through sunrise Monday morning.
Snow comes to an end by mid-morning Monday.
You can find what I'm forecasting for additional snow amounts (on top of what's already accumulated) tonight into Monday morning attached to this post.
Temperatures are now gradually falling to near or just below freezing across the area and radio scanner traffic seems to indicate roads are now getting slick.
Please be very cautious on roads tonight as the mixed precipitation changing back to snow will lead to slippery roads throughout tonight.
Also, be careful walking on any surfaces that have been cleared of snow as standing water and moisture on these surfaces will freeze up leading to icy conditions.
