For the next 5 to 7 days we will be stuck in a pattern of humid southwesterly flow between high pressure over the Atlantic Ocean and a mean low pressure trough to the west of New England. Weak frontal systems will try to push through from time to time, responsible for kicking off episodes of showers and thunderstorms, but none of these fronts will make a strong push through the region. I don’t see a big change in this pattern right into the middle of next week. The news here is mixed, since many people have outdoor plans for the long weekend, showers in that case are not so welcomed. But it has been dry in August, so any rain in that regard is welcomed. I believe that most of the shower activity will be north and west of Boston through Sunday and more likely anywhere in the region Monday. By Tuesday it should back off somewhat but the threat will still be there. It remains to be seen how much dry air works in by the middle of next week. I’m leaning away from it making a strong push into the region, at least initially.
