A cool comfortable morning means it was another fantastic night of sleeping weather. This is the last of these types of starts to the day for a while. Starting later tonight, the humidity comes back and it’s going to hang around for a while.
Interestingly, Martha’s Vineyard’s morning low fell to a chilly 39F under clear skies. This type of radiational cooling is typical for that location under the right conditions. Here in southern Maine we saw many inland areas fall into the 40s, but coastal locations hovered in the lower 50s.
In Portland, this month the most number of days in a row we had above 80 was four. Starting tomorrow we are going to see several days in a row close to or exceeding 80F. Since we aren’t really use to this type of pattern in early September and it’s back to the routine fall, it’s going to feel somewhat like a cruel trick of Mother Nature.
You likely have noticed it’s very dry in many places. Much of southern New England is in the abnormally dry category. This map also doesn’t take into account how dry some local communities are. While Portland and some other towns had the big rain on the 13th, it’s been 17 days since many have seen their last significant rain.
We have no chance of rain today under a sunny sky. Humidity levels will be comfortable and temperatures warm, but not hot. It will be warmer at the beaches, reaching the mid to even upper 70s depending on which way the shoreline faces. South facing coastlines will be coolest this afternoon.
As high pressure slips off the coast tonight the humidity will creep back into New England. If you sleep with the windows open, you may actually feel the moisture going up throughout the night. By tomorrow that feeling of mid-summer will be back and afternoon highs will reach well into the 80s.
All is not perfect however. There will be clouds tomorrow, especially in the afternoon and towards evening when showers and thunderstorms are possible. Like so many of the other situations this summer, some of us will see no rain, while others see up to half and inch.
On Monday, I expect a warm and humid day with a chance of showers and thunderstorms, but most of the day will be dry. There will be a blend of clouds and sunshine.
The rest of next week continues to feature a broad flow of warm air. The humidity levels should decrease for the second half of the week, but temperatures are going to stay on the higher side of average for early September.
Hurricane activity tends to peak during the second week of September. Now that Cristobal is out of the picture there are actually no tropical cyclones in either the Pacific or Atlantic Ocean. This is quite amazing for a time of the year when we normally would be either tracking a storm or at least one that was forecast to develop. Things can change rather fast and we’ll have to keep an out on the tropics through the fall.
