It’s Patriots Day in Massachusetts, and although the Marathon won’t be held until October, there’s still plenty going on today, and the weather should cooperate for the most part.
The day will start off with some sunshine and seasonably mild temperatures, but an upper-level disturbance will cross the Northeast today, allowing for some clouds, and probably a few showers, maybe even a thunderstorm, this afternoon. They shouldn’t be widespread, nor heavy, but given that we still have a significant rainfall deficit, every little bit helps. A cold front will move through on Tuesday, but with little fanfare aside from some clouds and possibly a shower or two. Ahead of it, temperatures will be quite mild, possibly topping 70 in some locations. That front will stall out near or just south of the South Coast Tuesday night, then lift back northward as a warm front on Wednesday as low pressure passes north and west of the region. With low pressure to our northwest, it’ll be quite mild again, but another cold front will approach from the west, producing another round of showers and thunderstorms.
Behind that front, high pressure builds in with much cooler conditions on Thursday and to a lesser extent on Friday. A few weak upper-level disturbances will also be moving through with some clouds at times, but little precipitation other than a stray shower. Next weekend looks unsettled, but the details are still a little fuzzy. A period of rain or showers and cool temperatures appears likely at some point, but will it be late Saturday and Saturday night as one model shows, or on Sunday as a different one indicates? We should have a better handle on that when we do our Weekend Outlook on Thursday.
