Warm & muggy weather yet again today and like yesterday the risk of late afternoon/evening thunderstorms is with us. Unlike yesterday there will be a hyperactive jet stream ramming into the warmth & humidity. Warmth & humidity all by themselves can easily pop strong thunderstorms but when you add in that jet stream wind you then have to be concerned with strong to severe storms.

The greatest risk of the severe thunderstorms will occur across western New England after 1pm today. Once those storms form they are likely to head through the CT river valley and eventually the Worcester Hills by mid-late afternoon. The greatest threats will be locally heavy rain, frequent lightning, damaging wind and even a slight risk of a tornado. Farther east  (inside I-495) the storm threat is minimal until this evening and by then the greatest concern will be frequent lightning as well as locally heavy rains. Before all this hubub occurs you can plan on a very humid & warm day with limited sun. Most towns will reach the low 80s–upper 70s on the Cape/South Coast.

By tomorrow, the weather offers more humidity as well as showers & downpours. Unlike today & yesterday though our rain threat tomorrow is early and often. Most towns will pick up close to an inch of rain overnight & through Wednesday. Rain should taper off to cloudy skies after 2pm (6pm on Cape Cod). Pleasant weather takes hold for the remainder of the week.
