As expected it was a warm and humid Thursday but unexpectedly sunshine prevailed through most of the day. The showers and thunderstorms that we thought would clip the greater Springfield area remained to our south with the heaviest activity along the Connecticut coast, Rhode Island and finally across southeast Massachusetts. We remained on the edge of the clouds from this system but overall it turned out to be a sunnier day than anticipated last evening. Temperatures had no problem climbing back into the 80s this afternoon.
The other feature we have been paying attention to is a cold front that is to our northwest. This front will play a big role in changing our weather over the next 24 hours. The front moves across the Pioneer Valley tonight and is forecast to be positioned across southeast Massachusetts by morning. Behind the front a cooler and drier air mass follows and settles in over the weekend.
Tonight there remains only a slim chance of a shower or isolated thunderstorm as the cold front approaches. Many of you will probably stay dry. It remains muggy and mild overnight.
Skies partially clear on Friday and we will be left with a 50/50 mix of clouds and sun. As the drier air starts to take over you will feel a noticeable difference as the humidity drops and temperatures will run several degrees lower from those of Thursday.
A few clouds may drift across the sky Friday night, otherwise a clear and cool night with temperatures taking a good tumble overnight as a touch of Fall returns.
High pressure presents itself for the weekend. A Fall like start to the weekend on Saturday with a sunny and cool start, becoming partly cloudy in the afternoon. Temperatures running about 5 degrees below normal. A chilly night follows Saturday night and then a return to more seasonal temperatures on Sunday with fewer afternoon clouds around.
By Monday the high pressure system sinks to our south and we are in a return flow of southwest winds. A warm front will also be a factor in the early week period and will bring clouds, humidity and the threat for showers by Tuesday.
