Yet another robust frontal system will pass through Western and Central Mass this afternoon and this evening. This front will cause a very significant change in the weather starting around mid and late afternoon today. Skies this morning into early this afternoon will be sunny to partly sunny and this will allow temperatures to rise to between 55 and 60 Degrees by midday. Turning to the mid and late afternoon hours, that frontal boundary will combine with some unstable air and quite a lot of forcing to produce a cluster of heavy showers and thunderstorms that will move through Western Mass by about 3 to 4 pm this afternoon. These heavy showers and thunderstorms will push across Central Mass starting around 4 pm and continuing until about 6 pm this evening. These heavy showers and thunderstorms are expected to be short-lived and look to only last for about an hour or so at any one location. Any of the heavy showers and thunderstorms will be capable of producing small hail given the very cold air aloft. In addition, temperatures are expected to rapidly fall through the 40s late this afternoon and this evening and may fall into the 30s in the Berkshires and the Worcester Hills. If that wasn’t enough, the heavy shower activity will produce a period of rather gusty westerly winds when they move through late this afternoon and this evening. Brief wind gusts of up to 45 to 60 mph are possible with this activity. Given that the trees still have a lot of leaves on them for this time of year, there is the possibility for some downed trees and power outages from the very gusty winds late this afternoon and this evening. Once the showers and thunderstorms end around 6-7 pm, skies will be clear to partly cloudy tonight with a sunny to partly sunny Sunday expected. Low temperatures tonight will be near 30 Degrees. High temperatures Sunday will be between 45 and 50 Degrees.
