Northeast

The next few days should feature continued cool but pleasant weather, with temperatures in the low 70s in the southern portions of New England and New York City and mostly upper 60s elsewhere for Thursday. On Friday, a secondary shot of cool air brings little moisture with it except a small chance of showers for far northern New England and upstate New York, but the greatest threat will be a widespread frost. Much of northern New England and upstate New York could see their growing season cut short, with a hard freeze likely for most of Vermont, New Hampshire and Maine.

East Central

Continued pleasant weather stays in the region through at least Saturday, with comfortable temperatures still running below average but sunny skies prevailing as well. We’re keeping an eye on a coastal low that could impact the Delmarva this weekend, but for now it looks like it’ll stay out to sea. It looks like the next chance for rain doesn’t arrive until Sunday in association with our next cold front.

Cooler air spills into the northern parts of the region, including Atlanta, Birmingham and Tupelo for Thursday, with highs lowering into the 80s. Afternoon showers and storms spread into South Carolina for Thursday before a front moves offshore. The weekend looks terrific for almost everyone (Florida, as always, the notable exception with afternoon showers and thunderstorms), with highs in the 80s and plenty of sunshine.
