While this week will start off with more of the same for New England, a gradual breakdown of the pattern we’ve been in will commence around midweek. A distinct cooling trend will also occur as the week pushes on.
MONDAY & TUESDAY
Monday and Tuesday will feature the same weather New England has seen for the better part of two weeks now. That is to say it will be warm with plenty of sunshine. The sunshine may be more filtered in places, especially on Tuesday, as high clouds and some wildfire smoke enter the picture. Widespread high temperatures in the 80s will continue. This all comes as the Rex Block over the east coast continues with a developing tropical system off the coast of the Carolinas.

WEDNESDAY-FRIDAY
The breakdown of this blocking pattern will be slow, as is usually the case with blocking patterns. In this case, the once strong area of high pressure over New England will continue to slowly break down while the remnants of a tropical system slowly push northward. The position of what’s left of the high pressure as well as the timing of a cold front dropping south into northern New England will ultimately determine just how far north showers reach during this period. It will be a close call with New England barely on the northern extent.
