MANCHESTER, N.H. – A sharp fall chill is on the way for southern New Hampshire as skies clear and temperatures tumble late this week. After a stretch of mild, sunny afternoons, Friday morning may bring patchy frost—especially in low-lying areas along I-93 and in rural Rockingham and Hillsborough counties. Gardeners and outdoor vendors should take precautions to protect plants and displays from brief freezing temperatures.
According to the National Weather Service in Gray-Portland, strong northwest winds today will usher in cooler, drier air that settles by Thursday night. Friday morning lows will dip into the mid-30s, with frost forming where winds relax. The agency advises residents to cover sensitive vegetation and to bring pets indoors before dawn Friday.
Despite the chilly start, the region will rebound quickly. Friday and Saturday bring sunshine and highs near the low 60s—perfect for leaf-peeping or late-season pumpkin patch visits. Winds will stay light, and visibility will be excellent for weekend drives across the Lakes Region and into southern Maine.
Sunday looks warmer, approaching the upper 60s under mostly sunny skies before a weak system may bring scattered showers early next week. No major travel hazards are expected through Monday, though early commuters should stay alert for patchy frost on elevated bridges and shaded roads Friday morning.
With Halloween decorating and fall festivals in full swing, this calm stretch offers ideal conditions for outdoor prep before the next cool-down late next week.
