Late Morning Storm Update

Snow continues to fall across all of Western and Central Mass as of the time of this writing.

It is expected to continue to snow across the entire area through midday.

By early afternoon, however, the snow will change to sleet and freezing rain first across the I-84, I-395 and Route 146 corridors by about 1 pm or so. The changeover line from snow to freezing rain and sleet will push northward reaching the Worcester Metro by about 2 pm or so this afternoon. This is about as far north as the changeover line should reach with the northern Worcester Hills and much of Western Mass remaining all snow. The exception could be across the lower Pioneer Valley where a changeover to sleet looks to occur during the mid-afternoon hours.

The changeover line from snow to freezing rain and sleet will then collapse to the southeast leading to all areas of Western and Central Mass to be all snow again by about 5-6 pm or so today.

All snow will come to an end by early this evening.

Additional snowfall amounts will range from 2 to 3 more inches across areas from I-84, I-395 and Route 146 northward to the Worcester Metro to 3 to 4 more inches of snow expected across the northern Worcester Hills and across much of Western Mass. The exception looks to be across the lower Pioneer Valley where 2 to 4 more inches of snow looks likely. It should also be noted that isolated additional snow amounts of up to 5 inches are possible across the northern Worcester Hills.

Slippery road conditions will continue to be very likely throughout the rest of today into early this evening. Extremely slick conditions are likely this afternoon across areas that see freezing rain and sleet, which does include the Worcester Metro, the I-290, I-395, Route 146 and I-84 corridors.

Snow Is Expected Late Tonight Through All Day Tuesday Across Western & Central Mass

Snow Is Expected Late Tonight Through All Day Tuesday: An area of low pressure is expected to track just to the east of Nantucket during Tuesday afternoon before heading for Nova Scotia on Tuesday night. This storm system is expected to bring a widespread snowfall to the entire area late tonight through all day Tuesday. This will be a fast moving storm and because of this, snow amounts shouldn’t be excessive.

Snow is expected to overspread the entire area between about 2 am and 4 am Tuesday morning. Snow will then continue through all day Tuesday before coming to an end around sunset Tuesday. It should be noted that the snow looks to change to a bit of freezing rain during Tuesday afternoon across areas, including I-84, I-190, I-290 and Route 146. All other areas of Western and Central Mass should remain as all snow.

I have attached our forecast snowfall map for this upcoming snowfall to this post. Overall, this looks like it’ll be a light and fluffy snowfall due to the very cold air mass that’s located over our area.

Low temperatures will be between 15 and 20 Degrees. High temperatures Tuesday will be near 30 Degrees. Winds tonight will be South at 5 to 10 mph. Winds on Tuesday will be East at 5 to 10 mph in the morning and North at 5 to 10 mph.

Early Afternoon Update On The Incoming Snow Squalls

An area of snow squalls is now pushing through far eastern parts of New York State and is heading eastward at a forward speed of about 35-40 mph.

It is expected that these snow squalls will push through the Berkshires over the next hour and reach the middle and upper Pioneer Valley of Western Mass around the 2 pm time frame and then reach the lower Pioneer Valley around 2:15-2:30 pm.

These snow squalls are then anticipated to reach the western Worcester Hills and the I-84 corridor around 3 pm and then reach the Worcester Metro, as well as the I-190 and I-395 corridors around 3:15-3:30 pm. The I-495 corridor should be hit by these squalls around 3:30-3:45 pm.

BE AWARE THAT these snow squalls will produce heavy to very heavy snow for a short period of time (up to 15-30 minutes) that will lead to a quick 1 to 2 inches or so of snow accumulation. In addition, wind gusts of up to 45-60 mph will accompany these snow squalls leading to a brief period of extensive blowing snow and near blizzard conditions. A few rumbles of thunder cannot be ruled out with these snow squalls when they move through.

I CANNOT EMPHASIZE ENOUGH THAT EXTREMELY HAZARDOUS TRAVEL CONDITIONS will be very likely when these snow squalls pass through your area. It's best to be off of the roads when these snow squalls move through.
