Widespread Showers & Maybe Thunderstorms Expected Saturday Night Across Western & Central Mass

For Tonight: A southwesterly wind flow will be in place across Western and Central Mass tonight well ahead of a cold front that’s now located over the eastern Ohio Valley. This all means that skies tonight will be cloudy across the entire area. In addition, there’s the possibility for a very isolated shower or two across areas that are west of I-91 and north of Route 2. Elsewhere across the area, conditions are expected to be dry tonight. Low temperatures tonight will be between 60 and 65 Degrees and it will be muggy. Saturday: A warm front is expected to push to our north during the morning with a cold front pushing into extreme Western Mass by late afternoon Saturday. This means that Saturday morning will be cloudy and there could be a stray very isolated shower or two. During Saturday afternoon, skies are expected to be partly sunny. In addition, a line of heavy showers and thunderstorms will be moving into the Berkshires by late Saturday afternoon. High temperatures Saturday will be near 75 Degrees and it will be humid. It will also be kind of windy on Saturday, especially during the afternoon with south winds gusting up to 25 mph during the morning and south winds gusting up to 35 to 40 mph at times during the afternoon. Saturday Night: A line of heavy showers and a few thunderstorms associated with a strong cold front will push across Western and Central Mass during Saturday evening. The timeline of these heavy showers and thunderstorms are such that it’s expected that they’ll reach the Connecticut River Valley by about 6 pm and then move into the Quabbin, the Worcester Hills and areas including the Brookfields and Brimfield around 7 pm. Areas from Sturbridge to Worcester are likely to be affected by this line of showers and thunderstorms between about 7:30 and 8 pm Saturday evening. Even though the low-level wind shear is expected to be fairly high, there’s likely to be very minimal amounts of unstable air. This means that widespread severe weather is not expected. Instead, this line of heavy showers and thunderstorms will produce wind gusts of up to 40-50 mph, briefly very heavy rainfall and a few rumbles of thunder. Once the cold front moves through, temperatures and humidity levels will fall, although there should be a few more hours of widespread shower activity that’ll finally come to an end between about 2 am and 4 am Sunday morning. Low temperatures Saturday night will be between 45 and 50 Degrees. Sunday Through Monday: A cooler air mass will push into the region for both Sunday and Monday. Both days look like they’ll feature a mixture of sun and clouds with a gusty northwest wind. High temperatures Sunday will be between 60 and 65 Degrees and high temperatures Monday will be between 55 and 60 Degrees. Northwest winds are expected to gust up to 25 mph on Sunday and northwest winds are expected to gust up to 35 mph on Monday. Tuesday Through Wednesday:An area of high pressure will very slowly build into the area during Tuesday into Wednesday. This means that I think that Tuesday will be partly sunny with high temperatures between 60 and 65 Degrees and Wednesday is expected to be generally sunny with high temperatures between 60 and 65 Degrees. Thursday Through Next Friday:We should be on the western side of that high pressure system on Thursday with a frontal system moving through the area next Friday. This means that Thursday will feature a mixture of sunshine and clouds with high temperatures between 65 and 70 Degrees. Friday looks generally cloudy and there will be some scattered shower activity. High temperatures Friday will be near 65 Degrees.
