Updated Significant Weather Weekly Outlook

Hazardous weather is not expected this weekend, but a significant change in temperatures lies ahead.  Saturday looks to be dry, albeit cooler than most of this past week for most interior areas.  Widespread showers are expected Sunday in association with a high amplitude upper trough and strong surface cold front.  An embedded thunderstorm or two is possible.  Also, rain may mix with or change to wet snow over the higher elevations of the Berkshires before ending but with very little/no accumulation.  Light accumulations are possible across the mountains of northern New England.  The precipitation should end by late Sunday afternoon over western sections of southern New England and during Sunday evening across eastern MA and RI.

Temperatures will drop to the lower 30s across central and western MA as well as northern CT Sunday night (upper 30s coastal sections).  Monday will be chilly with temperatures likely not getting out of the 40s followed by Monday night low temperatures dropping into the 20s across the interior.  Temperatures should gradually moderate during the rest of next week.
