Forecast discussion: High pressure over eastern Canada helped clear our skies by the late morning, giving sunshine to Boston by Friday afternoon. This high will protect us from any storms through the weekend, before we run into a week of unsettled weather.
For the weekend, high pressure will slowly come down from Quebec, and control our weather pattern for the weekend. High temperatures will be in the middle 70’s to near 80, while the nights will be cool. Overnight lows Saturday night will fall into the middle 50’s in some areas. However, temperatures the following night will be a bit warmer, with the low reaching 60.
As we enter the workweek, Monday looks fine, with bright sunshine and some fair weather clouds through the afternoon. However, a series of weak low pressure systems and cold fronts will be moving through New England. A cold front passes through Monday night, giving us some isolated showers and thunderstorms into late Tuesday afternoon. We will have a reprieve from wet weather briefly, before a new low pressure system brings some isolated showers and thunderstorms Wednesday afternoon. Finally, a new cold front will pass through Thursday morning, providing us with more isolated showers through the evening.
By Thursday night, high pressure ridging will build over Friday morning, providing us with a nice start to the holiday weekend. I am expecting mostly sunny skies with temperatures in the upper 70’s.
