If you thought the arrival of September would bring more fall-like air, think again. Temperatures and humidity are set to spike again this week.
Highs on Sunday will generally be in the 80-85 range, except for 70s for south facing coastlines. Humidity will gradually creep up during the day with partly cloudy skies.
There may be an isolated shower in far Northern New England, especially parts of Vermont and Northern Maine.
Labor Day features highs around 90 with oppressive humidity. Again expect some relative relief, highs in the 80s, for the Cape and Islands or other areas that face southwest. It’s still just as muggy there though.
A few more storms will rumble through far Northern New England as a cold front nears.
That front will drop south on Tuesday, bringing a few pop up downpours or storms to Southern New England, where it will still be muggy and hot. Highs will again be around 90. It will be a little less hot behind the front in Northern New England, but many places will still reach the 80s.
At the coast on Wednesday winds will briefly turn onshore, meaning temperatures will be around 80 with mid-80s farther inland. It’s still muggy and there may be a spot shower.
That drop in temperature doesn’t last because another warm front brings humidity and temperatures near 90 back on Thursday.
Late week into the weekend should finally feature more seasonable conditions with highs in the 70s.
