Sunshine to Start Before Mid-Week Thunderstorms, Downpours

Our weather team issued a First Alert for Thursday as strong storms and waves from Hurricane Larry show up in the forecast.

Delightful, early September weather brings a low-stress return to post-Labor Day school and work routines, at least when it comes to weather impacts! 

Crisp, cool morning temperatures are in the 50s (40s in Northern valleys) and daytime highs are on either side of 80° with low humidity. That crisp air makes it possible for one and all to enjoy comfort outside, with the only exception being for ragweed pollen allergy sufferers, as the pollen count remains high. 

With our progression to fall, the sun angle isn’t as strong as it was in the summer. Even unabated Tuesday and Wednesday sun will deliver a high, not very high, ultraviolent index – enough for sunburns with prolonged exposure, but not the intensity of mid-summer. 

For many coastal residents, the day after Labor Day is a favorite day of the year. Summer visitors have returned home and there’s plenty of space on the sand to go around.

Enjoy the midday high tide and one to two foot waves Tuesday, as our First Alert Team expects ocean swell to build a bit on Wednesday with a slightly elevated rip current risk. Then, more significant swells of four to eight feet are expected, with a strong rip current by Thursday and Friday as Hurricane Larry zips east of Bermuda and into the Canadian Maritimes. 

As for the skies, expect a strengthening south wind Wednesday to boost temperatures into the 80s all the way to the Canadian border. But an approaching cold front will trigger building clouds and incoming thunder to western New England by Wednesday evening into night, and some of those storms may be strong. 

Farther east, storms will slowly arrive from the west while weakening overnight Wednesday night, then the instigating cold front will likely slow to a crawl Thursday. That means recurring pockets of rain and embedded downpours are in the forecast for eastern New England Thursday with either side of an inch of rain.

Our weather team has issued a First Alert for Thursday, expecting an impact to one or both of the day's commutes. 

By Friday, the cold front eases off our coast, leaving only a very slight chance of a shower. Most of us will see great improvement, en route to another shot of dry, comfortable air with plentiful sun just in time for the upcoming weekend! 

Although a couple of disturbances show up in our forecast next week for an increased chance of showers both Monday and Wednesday, both systems look to be fairly quick-moving right now, so the exclusive First Alert 10-day forecast certainly shows more dry days rather than wet ahead!
