Pockets of Showers and Thunder Move In

Fog and clouds break for at least some sunshine Tuesday. But, with so much humidity in the air and another spoke of atmospheric energy moving overhead, expect pockets of showers, downpours and embedded thunder to develop Tuesday afternoon into early evening.

All of New England will be vulnerable to these downpours, though the Cape has a lower chance. Where the rain moves through, it’ll fall heavily in spurts, and may produce local areas of pooling water that should be avoided by drivers, as always.

Showers will wane Tuesday evening in Southern New England and overnight north, giving way to areas of fog, particularly where rain fell during the day.

Wednesday brings ample sun, boosting high temperatures near 90 with humidity driving the heat index over 90 degrees by afternoon. Showers and thunder will develop in Northern New England Wednesday afternoon but are less likely in Southern New England.

Noticeably less humid air arrives in Northern New England Thursday but is cut off at the pass by returning humidity. That same humidity will prompt new showers and storms Friday and Saturday afternoons.

The chance of storms diminishes Sunday and that’s because of an onshore wind that will probably keep clouds and cooler air around. It may leave a lingering onshore wind Tuesday before temperatures climb toward 90 again for the middle of next week in the Early Warning Weather 10-day forecast.
