The National Weather Service forecasts passing showers Sunday, Oct. 4, followed by dry weather and a sharper cooldown early this week.
It identifies inland frost potential as the next concern, with the coldest conditions arriving Tuesday night, Oct. 6, into Wednesday morning, Oct. 7.
Sunday’s rain should generally be light around New York City, northeastern New Jersey, and southern Connecticut. Coastal areas have the better chance of showers, while some inland communities could stay mostly dry. NWS forecasters do not expect flooding impacts in that region.
Farther south, AccuWeather’s Sunday map places rain across portions of Virginia, Maryland, and southeastern Pennsylvania. Boston’s NWS forecast keeps the daytime dry, with a chance of showers at night.
Monday, Oct. 5, brings increasing sunshine and a west or northwest breeze. Highs should reach roughly 65 to 70 degrees in Boston, New York City, and Washington, DC, before colder air arrives overnight.
Tuesday, Oct. 6, stays sunny but turns noticeably cooler. Afternoon temperatures should top out near 60 degrees in Boston and around 65 degrees in New York City and Washington.
The bigger concern develops after sunset.
AccuWeather forecasts frost or freeze potential across the Appalachians and interior Northeast into early Wednesday, Oct. 7. Northern Pennsylvania’s mountains and New York’s Adirondacks face a greater risk of a damaging freeze. Its map also includes inland portions of Connecticut and Massachusetts.
NWS forecasters say temperatures could reach the mid- to upper 30s in colder inland communities around the New York region, especially with clear skies and light winds. Sensitive plants may need covering or moving indoors.
Wednesday afternoon brings sunshine and a rebound toward 65 to 70 degrees in the major coastal cities.
Thursday, Oct. 8, remains sunny, with highs around 70 degrees in Boston, the lower 70s in New York City, and about 75 degrees in Washington.
