A gorgeous Wednesday in New England comes courtesy of a dome of high pressure, chock full of dry air.
Well to the west, a storm center is moving into the Great Lakes, and the counter-clockwise flow of air around that storm center is inducing a southerly wind across much of the Eastern United States. That flow is transporting increasingly warm and humid air northward.
Here at home, New England has too much dry air – and cool air, by nature, even though the sun warms it during the afternoons - to simply replace it with warmth or humidity. That clash of airmasses is destined not only to bring increasing clouds Wednesday evening and overnight, but developing rain from south to north Thursday morning.

Most of us squeeze in a dry Thursday morning commute before the rain arrives, with heaviest downpours slated for Thursday afternoon. However, the presence of clouds and cool air will mean high temperatures won’t exceed the 60s for most, and even 50s for some.
Some thunderstorms are likely to be embedded in the rain Thursday afternoon. Lingering showers, if not still some remaining downpours, will likely slow the Thursday evening drive with rainfall totals from our exclusive in-house forecast system predicted to be around an inch.
The weather starts improving as quickly as Friday morning with sunshine, though the upper-level atmospheric energy that helped spawn Thursday’s rainstorm will be moving directly over New England on Friday. This should make for some blossoming clouds with some scattered showers developing by midday and continuing to crop up during Friday afternoon, particularly inland.
Nonetheless, temperatures will start rebounding, owing to a sunny start and breaks of sun between any scattered showers. Another shot of dry air is expected to give us an incredible Saturday with highs in the 80s and low humidity.
It looks like an extended warm pattern sets up into early next week, but this will eventually mean increasing humidity, which favors at least some scattered showers or thunder on Father’s Day Sunday. Luckily, the day isn’t expected to be a washout at all.
Similar weather of warmth, increased humidity and scattered showers or thunder seems likely through at least the first half if not most of next week in the exclusive First Alert 10-Day Forecast.
