One more day in the heat and humidity before we get a welcome break in the summer weather and a return to a more seasonal and comfortable airmass. A warm front has pushed off the coast this morning with winds shifting to the SW. Hazy sunshine will help to spike temps into the 80’s near 90 by midday. Dewpoints are climbing into the 60’s nearing 70. A hot muggy day for sure. There will be a few areas spiking into the Lwr 90’s in areas who see more sun lasting into the afternoon. The best chance of this will be CT, RI and SE MA…mostly south of Boston…still near 90 even downtown, but the humidity will make it feel warmer. Clouds will help hold down temps from really scorching today.
Showers and T’storms moving from the Great Lakes to upstate NY are weakening in a NW flow. They are having a tough time holding together. There is not much instability in the atmosphere today. Still a midday shower in eastern MA is likely, with a mix of clouds and breaks of hazy sun. As the cold front moves into SNE during the afternoon, more surface convergence could pop up a few more showers or storms in SE MA. This is all hit or miss, so the good news is most of the day will be dry.
A complex of thunderstorms is better organized near Lake Ontario. This will be sliding towards CT and the south coast by late in the day and evening. This area is under a slight risk of storms by the Severe Storms Prediction center. Storms may strengthen along the front along the south coast tonight before pushing off the coast. The rest of us will see clearing skies later tonight with humidity levels starting to fall overnight.
Sunday will be mostly sunny and beautiful with dewpoints falling into the 50s’s, but temps will remain warm in the 80’s to near 90 in spots. Air will continue to be on the move from Canada the next few days as a broadscale trough develops in the Northeast. This will break down the record breaking heat wave for part of the nation and push the heat towards the western half of the nation. This will be about as good of a week of weather you can ask for with temps near 80-85 degrees, sea breezes at the coast, low humidity and plenty of sunshine. The dry weather will hold to the end of the week with a front stalled well south of New England.
Once the trough lifts out next weekend, a Bermuda high pattern will develop on the eastern seaboard which will signal a return to the warmth for the east coast.
