Heat & Humidity Returns In Force On Thursday & Especially On Friday Across Western & Central Mass

For This Afternoon: The high pressure system that has brought the region some very comfortable humidity levels the last couple of days will push to the east this afternoon. This will lead to a southwesterly wind flow to develop leading to a little increase in the humidity values this afternoon.

Partly sunny skies are expected throughout this afternoon with temperatures around 80 Degrees. Dew point temperatures will be in the mid to upper 50s. Winds will be Southwest at 6 to 12 mph.

Tonight: Clear to partly cloudy skies are expected with low temperatures around 60 Degrees. Winds will be Southwest at 10 to 15 mph.

Thursday: A very warm and humid day is expected on Thursday under sunny to partly sunny skies. High temperatures will be between 84 and 89 Degrees. Dew point temperatures will be between 60 and 65 Degrees. Winds will be Southwest at 10 to 20 mph with gusts to 30 mph.

Thursday Night: Partly cloudy, warm and humid conditions are expected with low temperatures between 65 and 70 Degrees. Winds will be Southwest at 10 to 20 mph.

Friday: A hot and humid day is expected under partly sunny skies. High temperatures will be around 90 Degrees and dew point temperatures will be around 70 Degrees. Winds will be West to Southwest at 10 to 20 mph with gusts to 30 mph.

A cold front is expected to move through the area during the late afternoon and evening hours. The unstable air mass associated with the hot and humid conditions will combine with the energy and forcing from the cold front to produce scattered thunderstorms across the area from about mid-afternoon until about early evening. While I think most of the thunderstorm activity will be non-severe, it’s possible that a couple of the storms could be on the strong side and produce up to 40-50 mph wind gusts, frequent lightning and torrential downpours.

To sum it up, I think that we’ll see some scattered thunderstorms starting around mid-afternoon and lasting until early evening. A couple of the thunderstorms may be on the strong side and be capable of producing up to 40-50 mph wind gusts, frequent lightning and torrential downpours.

This Weekend: No weather problems are anticipated for this weekend as a weak high pressure system controls the weather.

Saturday looks partly sunny with high temperatures between 80 and 85 Degrees. Dew point temperatures will be between 60 and 65 Degrees.

Sunday looks partly sunny with high temperatures between 80 and 85 Degrees. Dew point temperatures will be around 60 Degrees.

Much Improvements In The Weather Are Expected During The Rest Of Tonight With Nice Weather Expected For Monday & Tuesday Across Western & Central Mass

All thunderstorms are now well out of the area at the time of this post.

For The Rest Of Tonight: Skies are now expected to become clear by midnight tonight with clear skies then expected during the after midnight hours. Low temperatures will be between 60 and 65 Degrees. Winds will be Northwest at 10 to 15 mph.

Monday still looks to be a nice day across the region with much more drier air moving into the region. Skies will feature a mixture of sunshine and clouds with high temperatures near 75 Degrees. Dew point temperatures will fall from the 50s during the morning into the mid to upper 40s during the afternoon. Winds will be Northwest at 10 to 20 mph.

Tuesday looks even nicer than Monday with lots of sunshine expected. High temperatures will be between 70 and 75 Degrees. Dew point temperatures will be near 45 Degrees. Winds will be West to Northwest at 5 to 10 mph.

6:20 pm Thunderstorm Update

Thunderstorms now stretch from the I-190 corridor southward through the Worcester Metro and then southwestward into Sturbridge and Southbridge & along I-84. These storms continue to head in a east-southeasterly direction at a forward speed of about 30 mph.

It is expected that areas along I-190, the Worcester Metro to Sturbridge, Southbridge and Charlton will continue to be impacted by the storms over the next 30-45 minutes with torrential downpours and lightning.

These storms will then affect areas around I-395 and Route 146 by about 6:30-6:45 pm and then last until about 7:15-7:30 pm. Again, these storms will mainly produce heavy downpours and lightning.

All storms should push out of all of the area between 7:30 and 8 pm and we should then be done with thunderstorms for the evening.
