For some of us, it’s still the weekend on this Labor Day Monday. But for continuity, this post will do its typical look at the 7 day period Monday through Sunday.
What happens when the temperature and the dewpoint meet? The air saturates, and did that happen quickly in much of northeastern and east central MA during the first hour of the new day. We went from a mostly clear sky to heavy fog in a matter of moments. As the sun rises and goes to work on the fog bank where it is (not everywhere will fog in but many places will during the pre-dawn hours), the fog will thin and dissipate with sun taking over. A great day is in store!
Then begins a 3-day unsettled period Tuesday through Thursday. The heaviest and most widespread rainfall is now expected to take place Tuesday night and Wednesday morning. Getting the timing right on these is always a fun task. Anyway, some locations may see 1 to 2 inches of rain and even heavier amounts. The most likely area for the heaviest amounts as it stands now will be southern NH, but much of MA and even parts of RI can get in on the heavier action as well. A final cold front will pass through on Thursday, but it is unclear how much shower and thunderstorm activity will be associated with this. One thing is for sure, tropical humidity is going to be locked in for the 3-day period.
Friday and at least the start of next weekend look much better as high pressure moves in. However, Hurricane Leslie will be offshore in the Atlantic and sending large ocean swells to the New England Coast. Rip current threats will be high by the end of next week, and some areas prone to coastal flooding may see some, due to heavier surf and large swells. The storm itself will stay far offshore and never reach New England.
