Morning Low clouds are thinning and breaking for some increasing midday and afternoon sunshine. Low clouds linger a bit longer at the coast…especially on the Cape. West winds along with increasing hazy sun will give a warm muggy to feel to the air this afternoon with highs climbing into the 70’s and Lwr 80’s. Light winds will mean a seabreeze at the coast
A cool pool of air aloft and an approaching shortwave from the Great lakes moves back towards New England later today. Clouds are already advancing from the west, so the window of sunshine will be limited. Clouds will be increasing by mid-late afternoon with a chance a few pop up showers or thunderstorm late today with just enough surface convergence along a weak front into the early evening. Very hit or miss.
The shortwave will swing through and off the coast tonight. Early clouds become partly cloudy…with overnight clearing with humidity levels dropping overnight. Weak high pressure follows in for sunshine and fair weather clouds Monday. We loose the humidity but will keep the warm with highs in the Lwr 80’s and sea breezes at the coast.
Clouds will be increasing Tuesday ahead of the next cold front. Much of Tues will remain dry, but more humid with increasing boundary layer moisture with highs still 80-85. Showers will push in Tuesday night through Wednesday morning. Locally heavy downpours with some embedded thunder possible into the morning hours Wednesday…with some slow improvement by the afternoon.
High pressure returns with sunshine and seasonal temps to end the week with highs in the 70’s and Lwr 80’s. Nice looking end to the week.
Looking ahead to the July 4th weekend there is uncertainty and at least some weather to watch which could provide showers . A cold front will be working it’s way eastward and will pass through the region at some point with a round of showers and thunderstorms. The timing is speculative and will change in the coming days. A warm front could create showers Saturday, with a cold front making more showers/storms Sunday. An upper low over the maritimes will supply the cool air aloft for instability, and suppress the sultry summer warmth mainly south of New England keeping us in the 70’s….unsettled with the potential for clouds…and hopefully SOME sunshine along the way. The extended outlook simply needs more time…but it does not look ideal today….
