As we approach the long Labor Day weekend, the temperatures will take a break from their last extremes. But do not get used to the cooler weather – we're looking at more heat and humidity that will arrive later this weekend and last for the next week.
Temperatures for Friday will come out of the water in the middle of the 70s. We will also see temperatures below 80 for Saturday. On Sunday, readings will continue until the 1980s and you will notice an increase in humidity. Monday is hot and a good day at the beach. The heaviest cloud cover will be Friday and the first part of Saturday.
I'm not forecasting rainfall this weekend. However, there is a small window for a brief spatter Sunday night or Monday when humid air arrives. There will be a mix of clouds and sunshine this weekend (lower dew points will start, but high dew points will be over).
The dew point loop shows the dry air, which moves briefly before the higher humidity comes from the south on weekends. (Note that dew points are expected at or above 70 in New England.) This means that it feels tropical again on Sunday afternoon and on Labor Day.
Dew points will increase significantly this weekend.
