Sea breeze today. Storms can fire up near the boundary of this sea breeze (mainly south, west, and northwest of Boston) and further west in the heat (air mass storms). Any storms that form today will likely be non-severe but can produce flash flooding where they occur, as they will be slow-moving storms that rain themselves out nearly in place at times. Most areas will see little or nothing.
Tonight, any activity quiets down with no solar heating to be had. The air mass will be warm and muggy.
Sunday will be a dry day. No storms are likely to form during the day save for a slight risk of a pop up isolated storm over the hilly terrain. The main action will approach late at night from the west, with a cold front. The timing of this front, late Sunday night and early Monday, will probably eliminate the threat of severe weather and may significantly limit thunderstorms overall. We will probably see a nasty squall line coming out of NY State late Sunday evening that will then begin to weaken as it makes the trip across New England. I’ll keep an eye on any activity, in case.
Once we get that front by on Monday, it looks like a couple of warm and more comfortable August days heading into the middle of next week.
