MANCHESTER, NH – A low gray sky hangs over southern New Hampshire early this morning as steady rain slicks city streets and leaves swirl across driveways. The air feels heavy, mild, and damp—but colder air is already gathering to the north, setting up a quick shift toward true fall chill by midweek.
According to the National Weather Service in Gray, Maine, widespread rain and isolated thunderstorms will track across Hillsborough and Merrimack Counties through early afternoon. Some heavier downpours could briefly reduce visibility along I-93 and Route 101, while gusts near 30 mph may rattle loose branches. Showers taper toward evening as drier air filters in from the west.
Tuesday brings a bright, crisp rebound under full sun and lighter southwest breezes. Highs reach the mid-60s, making it one of the week’s most pleasant days for outdoor errands or school sports. But another fast-moving system late Tuesday into Wednesday promises another round of showers—followed by a sharper cool-down.
By Thursday, high pressure settles in, clearing skies but dropping temperatures. Afternoon readings will struggle to reach 60, and rural valleys north and west of Manchester could dip into the mid-30s by Friday morning. That pattern signals the first early chance of a fall frost across interior New Hampshire.
Residents planning yard cleanup or late gardening should cover tender plants and drain outdoor hoses soon. This mild spell is fading fast, and Halloween week looks set to arrive with unmistakable early-winter air.
