Areas Of Light Icing This Afternoon Across The Pioneer Valley Of Western Mass & The Northern Worcester Hills: Some areas of light precipitation will overspread Western and Central Mass this afternoon. It appears that cold air will get locked in across parts of the Pioneer Valley/I-91 corridor of Western Mass as well as across the northern Worcester Hills. This means that areas of light freezing rain and freezing drizzle are possible across these areas this afternoon.
Any freezing precipitation this afternoon may lead to roads becoming icy. If you live in the Pioneer Valley of Western Mass or in the northern Worcester Hills, be careful when driving or walking this afternoon and early this evening as icy conditions are possible in some areas.
Heavy Rain Expected Late Tonight Through Saturday Morning: A strengthening area of low pressure moving across the area tonight and Saturday will push a lot of moisture into our area.
Showers this evening will translate into a widespread heavy rainfall event from late tonight through Saturday morning. Rainfall amounts of 1 to 2 inches are expected with locally higher amounts likely.
Given the heavy rainfall that is expected combined with the significant amount of snow melt that has already occurred this month, there is the potential for flooding later tonight through Saturday. So, not only is river and stream flooding possible, but also some urban and poor drainage flooding is also expected late tonight through Saturday morning.
The temperature forecast on Saturday is going to be a real bug-a-boo as it’s possible that much of Western and Central Mass may remain in the upper 30s to low 40s for much of the day. Temperatures may not rise into the middle or even upper 40s until Saturday evening.
A break in the rainfall is possible for a while on Saturday afternoon, however, additional rain showers are expected late Saturday afternoon and Saturday evening as an associated cold front pushes through. In addition, a rumble or two of thunder is also possible later Saturday afternoon and Saturday evening.
Rain will finally come to an end around midnight Saturday night.
Sunday: Sunday is expected to be a generally cloudy and windy day across Western and Central Mass with high temperatures near 45 Degrees. West winds will gust up to 30 to 40 mph at times throughout the day on Sunday.
Snow & Ice Expected From Monday Night Into Tuesday: Another storm system is expected to cross southern New England later Monday night and Tuesday.
It appears that there will be plenty of cold air around at the start of the storm so that the precipitation will start as snow between about 7 pm and 10 pm Monday evening.
Milder air will start to move in later Monday night and this will cause the snow to change to freezing rain and sleet by early Tuesday morning along and south of the Mass Pike. North of the Mass Pike, the precipitation may stay as all snow right into Tuesday morning.
During the day on Tuesday, a mixture of freezing rain and sleet looks possible for much of the day south of Route 2. Along and north of Route 2 and across the Berkshires, it appears that mostly all snow will occur during the day on Tuesday.
All precipitation with this storm system will come to an end late Tuesday afternoon.
It is still way too soon to start talking exact snow and ice accumulations for Monday night and Tuesday.
At this time, it is way too early to start talking exact snow amounts for the early week storm. I will say, however, that it still looks like that there will be enough snow to plow before the snow changes to ice south of Route 2. Along and north of Route 2, a moderate sized snowfall is possible (6 inches??).
I also want to add that ice accumulations from the freezing rain could be a real concern starting early Tuesday morning and continuing throughout the day on Tuesday.
I am watching this storm closely and will keep you all updated.
