I can't really think of a more important week for a meteorologist here in New England. The July 4th holiday week, where so many people are off with all sorts of outdoor activities. The pressure to deliver sunshine and more importantly--get the forecast right if it does feature rain. Gulp.
Today and tomorrow are the only two days this week that will offer widespread showers that could occur at any point in the day. Not saying that it will rain all day each day in the area just that the showers will be scattered and not confined to the *late day* moniker. I think the highest chance of showers this morning will be south & east of Boston while the afternoon hours will see north & west of town with the greatest chance of rain. Metro Boston will a decreasing chance of showers throughout the day. Some of those showers will be quite heavy across southern New Hampshire. So much so that a flood watch is in effect until tonight where 1-2" of rain is likely in the heavier downpours. What is a lock is the humidity--that's all over southern New England.
As we roll toward Wednesday and beyond, the summertime Bermuda High begins to build into New England. This will dry things out in terms of lowering the chance of thunderstorms (as well as confining them to late day) and allow our temps to approach 90. As of now, the 4th looks hazy, hot & humid with daytime temps in the low 90s and evening temps in the low 80s. Only a small chance of some late afternoon-early evening t-storms across western & northern New England.
Enjoy your week--be safe!
