A Soaking 1 To 2 Inches Of Rain Is Expected Monday Afternoon & Monday Night Across Western & Central Mass

FOR THE REST OF THIS AFTERNOON: A west and northwesterly wind flow has introduced a little bit of unstable air over the region. This has led to the development of scattered cumulus clouds across Western and Central Mass as of early this afternoon. In addition, radar imagery revealed there are some scattered showers occurring to our north across southern Vermont and southern New Hampshire.

It is expected that these scattered showers will gradually push southward into our area as the afternoon progresses. This means that there could be a few showers and perhaps a thunderstorm or two across mainly Central Mass during late this afternoon and this evening. Any thunderstorms are likely to not be strong or severe. That said, some locally heavy downpours will accompany any thunderstorms late this afternoon and this evening.

It will continue to be windy throughout the rest of this afternoon with West to Northwest winds of 15 to 25 mph with gusts to 35 mph.

Temperatures during the rest of this afternoon will be in the middle 70s.

SUNDAY looks to start out partly sunny during the morning, however, as we get into the afternoon we should see a buildup of cumulus clouds due to instability across the region.

3 pm Weather Update For Western & Central Mass

Radar imagery as of the time of this post indicated that some thunderstorms have developed over the middle and upper Pioneer Valley of Western Mass. In addition, a line of strong to severe thunderstorms are about to enter the northern Berkshires.

The thunderstorms over the middle and upper Pioneer Valley are moving towards the northeast and will likely affect areas of the upper Pioneer Valley and the Route 2 corridor from about Greenfield eastward to about Gardner over the next 30-45 minutes. Torrential downpours and some gusty winds are the main threat for now, but they will need to be watched in case they become severe.

The line of strong to severe thunderstorms now entering the northern Berkshires will reach the I-91 corridor from about the Vermont-Mass border to about Amherst by about 4 pm or so. Wind gusts of up to 50-60 mph, torrential downpours and frequent lightning will accompany these storms.

Elsewhere across Western and Central Mass, all is quiet for now, but I'm watching other storms trying to form and strengthen over the Berkshires and am also watching a line of thunderstorms pushing across eastern New York.

More updates will be posted as needed.
