Isolated Showers Likely to Weaken This Evening, Favorable Conditions Linger

An upper-level disturbance passing over New England delivered clouds the first half of the day then cleared from north to south during the afternoon.

These clouds had trouble producing anything more than some sprinkles, but the next incoming disturbance arrives Tuesday afternoon and will spark a few scattered thunderstorms in Maine. Areas in the Pine Tree State that will be particularly affected include central, eastern and northern Maine.

A few isolated showers in the Northern mountain may settle southeast into central New England as they weaken early Tuesday evening.

Patchy fog is possible overnight Tuesday night ahead of another very warm day Wednesday with ample sunshine and just the chance of an isolated shower. Though humidity slowly increases, it won’t be all that noticeable until Independence Day.

Even then, we’re unlikely to find the sultry summertime swelter all too common for New England summer. Rather, the moderate humidity and lack of strong atmospheric disturbances will likely be insufficient to touch off any thunderstorms for the July Fourth holiday in New England.

This means there's an absolutely perfect summer day near 90 degrees and just a bit cooler at the coast, where sea breezes kick in during the afternoon.

Fireworks on all nights look wonderful. The next increased thunderstorm chance is Saturday with the approach of a cold front. By then, it will turn into some thick and humid air. Although Sunday brings a decrease in both humidity and heat, a follow-up disturbance may trigger another shower or storm before clean, fresh air takes over early next week.

This awaits the next slow build of heat and humidity for the middle to end of the week in our exclusive First Alert 10-Day Forecast.
