Moderate-Heavy Snow Very Late Tonight & Tue Morning; Ice Tue Afternoon Across Western & Central Mass

For The Rest Of Today: A mixture of sunshine and clouds are expected throughout the rest of today. High temperatures this afternoon will be between 34 and 38 Degrees.

Moderate To Heavy Snow Very Late Tonight Into Tuesday Morning Followed By Freezing Rain & Sleet Tuesday Afternoon Across Western & Central Mass: Skies are expected to become cloudy by midnight tonight ahead of an area of low pressure approaching from the southwest.

Snow will begin overspreading Western and Central Mass after midnight tonight with the snow beginning along and south of the Mass Pike between 1 am and 3 am. The snow will then reach the upper Pioneer Valley and northern Worcester County by about 4 to 5 am Tuesday morning.

During Tuesday morning’s commute, the upper Pioneer Valley and northern Worcester County may be able to escape a nasty commute with some light snow before the snow intensity increases later Tuesday morning.

Areas near and south of the Mass Pike, however, will likely see a significant impact to the Tuesday morning commute. Moderate to possibly heavy snow will be falling during much of the morning commute with 1 inch per hour snow rates occurring. Poor road conditions are expected due to the moderate to heavy snow & extreme caution is advised for the morning commute. A quick 2 to 5 inches of snow accumulation is expected for areas near and south of the Mass Pike before the snow begins to change to freezing rain and sleet.

During the mid and late morning hours of Tuesday, the changeover line from snow to freezing rain/sleet is forecast to reach the Mass Pike by about the 9 to 11 am time frame and may very briefly reach as far north as Route 2 around midday.

During Tuesday afternoon, I think that snow will continue across the Berkshires, the far upper parts of the Pioneer Valley of Western Mass and across northernmost Worcester County. Across the rest of Western and Central Mass, I think that we will see freezing rain and sleet continue throughout Tuesday afternoon before changing back to snow during Tuesday evening.

The snow will gradually come to an end across the area around midnight Tuesday night.

All-in-all, my best educated guess based on looking at all of the available weather data is for snow accumulations of 3 to 5 inches across much of Western and Central Mass with the higher amounts occurring in the vicinity of the Mass Pike. In fact, I have concerns that some locally higher snow amounts are possible along the Mass Pike where the snow may come down the hardest during Tuesday morning before changing to freezing rain and sleet.

Further north across the upper Pioneer Valley and northern Worcester County (Route 2 corridor), the snow should be lighter in intensity, but it will probably continue through Tuesday afternoon and well into Tuesday evening with no prolonged changeover to freezing rain and sleet expected.

Any ice accumulations later Tuesday morning through Tuesday afternoon will be light across Western and Central Mass. A narrow area of one tenth (0.10) to two tenths (0.20) of an inch of ice is possible across northern and central Connecticut into northern Rhode Island.

Travel Conditions: A significant impact to the Tuesday morning commute is expected near and south of the Mass Pike due to moderate to heavy snow accumulations. Delays and/or cancellations seem likely on Tuesday due to the time of day of the heaviest snow accumulations. Freezing rain and sleet during Tuesday afternoon will lead to a poor Tuesday afternoon commute across Western and Central Mass, especially along and south of the Mass Pike.

I continue to keep a very close eye on this storm and will keep you all updated.
