It still looks like we will see the first snowfall of the season across much of Western and Central Mass from late tonight through Friday morning. So, let’s take a look at what’s going to happen: Rain is expected to continue This Afternoon across all of Western and Central Mass with temperatures in the upper 40s to low 50s. Tonight: The remnants of Tropical Storm Zeta will track to the south of New England this evening before another low pressure begins to approach our area late tonight. This means that rain will continue this evening across all of Western and Central Mass. As we get into later tonight, rain will gradually change to snow as colder air begins to move in on the backside of Zeta and the winds shift into a northerly direction. The changeover from rain to snow is expected to occur first in the Berkshires and the northern Worcester Hills around midnight or so. The completion of the changeover from rain to snow is expected across all of Western and Central Mass by about sunrise Friday morning. So, it’s fairly likely that it will be snowing everywhere across Western and Central Mass when the sun comes up tomorrow morning. Friday: That second low pressure system will head across southern New England during Friday morning. The moisture and energy from this low pressure system combined with colder air moving in at the same time will lead to a burst of snow throughout Friday morning across all of Western and Central Mass. At the same time this is occurring, temperatures are likely to fall into the low 30s for a while tomorrow morning and while most of the snow accumulation will occur on non-paved surfaces, some roads could become snow-covered and slippery for a while, especially in the higher elevations. The snow is expected to come to an end between about 12 pm and 2 pm Friday afternoon with some rise in the temperatures expected during the afternoon with high temperatures of between 35 and 40 Degrees. My latest forecast snow accumulations can be found with the map attached.
