Tomorrow is not going to be an ideal day to go golfing or boating or even go to the beach for that matter. We got our very nice day today and we will have to pay for this nice weather tomorrow. Rain is currently in the Ohio River Valley, giving parts of Indiana, Ohio, Kentucky, and into Pennsylvania some good soaking rains. The rains associated with this front are returning the warm and humid air. The air that we worked so hard to get rid of Friday. The heat is coming back after this rain as well. Not tomorrow. Tomorrow we will see rain-cooled highs, mainly in the 70's, to perhaps around 80 in places like Bedford, MA and Boston metrowest. Here, I do not think they will see much if any rain. The computer models keep much of Massachusetts rather day and give good soaking rains to southern CT and extreme SW RI. Even the Cape may escape much of the worst of it.
The Cape could use some rain as I was down on vacation there for the past few days and the lawns and fields are bone dry. Where there is not any sprinklers, the grass is brown. They really need the rain down there. The salty ocean air doesn't help much either with that problem. But where the rain falls heaviest tomorrow in extreme SW SNE and much of northern VT and NH, there could be as much as an inch of rainfall, with more in locally slower thunderstorms and downpours. I wouldn't be surprised if someone winds up with 2-3" somewhere in New England tomorrow. Just not in the light green area. This area will likely just get a few passing downpours from time to time, and mostly in the later PM.
The heat returns with the humidity for one day; Tuesday. Temperatures could get up to between 85-90 at the coasts and between 88-93 inland. The humidity will be oppressive, with dewpoints getting back in that 65-70 degree range for Tuesday and perhaps Wednesday as another batch of rain and thunderstorms moves in, this time with a cold front. Then we will have dry weather with highs seasonable, upper 70's to around 80.
