The weekend is going to start off unsettled, but the rest of it looks terrific.
High pressure will slide offshore tonight and Friday, with southwest winds bringing warm and increasingly humid air into the region. A cold front will approach from the west during the day on Friday. A line of showers and thunderstorms will develop ahead the front. Conditions should be ripe for some of these storms to become strong to severe during the afternoon and evening, especially north and west of Boston. Some of the storms produce hail and strong winds, with heavy downpours also likely. As the storms move into the Boston area and southeastern Massachusetts they should start to weaken, but some gusty winds and heavy downpours are still possible. The front moves offshore at night, bringing an end to the showers and storms, though they may not end completely until close to daybreak across parts of the Cape and possibly southeastern Massachusetts. High pressure then builds back in for Saturday and Sunday with cooler and drier air. By Monday, the high will move off to the east and warmer and more humid air will start to move back in. This will be the beginning of what looks like a hot week , but we’ll get into more details on that in our Weekly Outlook Sunday night.
