As I have been mentioning on TV today, we are in a bit of a squeeze play today. A low, which gave the Cape some early morning rain, is pulling into the Gulf of Maine. Sinking air on the backside of this departing low is breaking the clouds across the interior of New England. Also, a dry slot is following in up from the south. Lingering low clouds at the coast through the morning, but by afternoon, even these clouds will break for some partial sun at our eastern facing beaches during the afternoon. Light onshore winds will keep it cooler at the coast in the 70’s, but where there is breaking sunshine and brighter skies, high temps will climb into the Lwr 80’s this afternoon. A cold front to our west with more clouds will be pushing into New England late today with scattered showers or a thunderstorms…mainly reserved for western New England. Much of the day will be dry for outdoor events and this afternoon just may be alright…just warm and muggy!

A large upper low is sitting over the Great Lakes with a large broadscale trough in place in the Eastern US. This is steering warm humid air up the east coast with SW winds aloft. SW flow is slowing the passage of the front. Most importantly, we have to watch are showers and T’storms which are tracking up the east coast off the mid -Atlantic coast. These showers and storms will likely be pushing into SNE tonight in the form of heavy downpours and thunderstorms in the hours of 9 PM-2 AM. Heaviest rain will be in RI and Eastern MA. Once this off the coast, we still have the cold front to push through on Monday. This cold front will trigger a few showers during the morning into the midday..with the potential of a thunderstorm in these humid conditions. The front will push off the coast in the afternoon, shies will be increasing with sunshine and falling humidity. After a mild muggy start, WSW with increasing sun will spike temps back into the lwr-mid 80’s

As our upper low lifts out, High pressure follows in for the midweek with beautiful dry air; Sunshine with highs in the Lwr 80’s. A Perfectly seasonal airmass to kick off the month of August. After some weak midweek ridging in the upper levels of the atmosphere, supplying weather of comfort, another upper level low will begin to spiral into the pattern, but mostly remain across the Canadian border. This upper low will spin a series of short waves towards us which could ignite a shower or thunderstorm anytime in the Thurs-Fir-Saturday time frame as warmer temps begin to build.
