MANCHESTER, N.H. – Wisps of fog drift across the Merrimack Valley this early Saturday as New Hampshire wakes to another chilly, still morning. Car windshields sparkle with frost under clear skies, the calm start marking a classic late-October transition — crisp days, damp lows, and a hint of early winter waiting just beyond the weekend.
According to the National Weather Service in Gray, today stays mostly sunny with highs near 55°F before calm winds settle again tonight. Fog forms quickly after sunset, especially in low-lying spots along I-93 and Route 3, reducing visibility into early Sunday. Sunday brings partial clearing and similar temperatures, though fog could slow morning travel and flights at Manchester-Boston Regional Airport.
By Monday, patchy fog gives way to more filtered sun and a mild high around 53°F, the last steady day before a weak front edges into New England. Scattered showers are likely to arrive late Tuesday, marking the region’s first tangible shift toward a cooler, unsettled Halloween stretch.
Residents should keep headlights on through fog zones, allow extra minutes for early drives, and cover any late-season plants still out in gardens as lows dip near freezing both Sunday and Monday mornings.
Midweek looks breezier and damp, but no snow is expected yet. Still, forecasters note colder air trailing behind the Tuesday system could set the stage for New Hampshire’s first early-November frost run.
