The first day of September feels like the first day of October as high temperatures today only stretch into the mid to upper 60s, which about 10 degrees cooler than normal. We enjoy the taste of fall for the first half of the holiday weekend. Saturday is another cool start with morning lows kicking off in the 40s for most, a spot upper 30 cannot be ruled out.
Saturday afternoon brings nice and pleasant conditions as a dome of high pressure slides in from the northwest, blocking Harvey’s remnants temporarily. The big dome of high pressure over New England is short-lived as it slides out to sea late Saturday evening, clouds slide in ahead of the rain associated with Harvey.
The moisture associated with remnants of Harvey work their way in by early Sunday morning, starting south and spreading northeastward, with a few heavy downpours for the Cape and the Islands possible. A few more embedded downpours are possible through midday spreading from southwest to northeast into parts of New Hampshire. Remnants of Harvey should clear the area by late Sunday evening, giving way to a nice Labor Day Monday.
High temperatures this weekend range from upper 60s to low 70s both Saturday and Sunday with more cloud cover Sunday along with those scattered showers. Monday brings highs back to near 80 under partly sunny skies. As everyone heads back to work or school on Tuesday after the long holiday weekend, highs Tuesday will remain in the low 80s with humidity sliding back in, then we see the chance for showers midweek, lowering humidity and the high temperatures back into the lower 70s by Wednesday.
We are still watching the Tropics as Hurricane Irma is expected to strengthen to a Category 3 as it closes in on the Leeward Islands by Wednesday. We are continuing to track Irma as some weather models hint to Irma sliding up the east coast. As always stay tuned for the latest updates on your local forecast and on the tropics as we are halfway through the hurricane season.
