HUNTSVILLE, Ala. – A dense, silvery fog hangs low across the Tennessee Valley this Halloween morning, coating lawns and rooftops in a delicate layer of frost. Streetlights glow faintly through the mist as northern Alabama awakens under a Frost Advisory, in effect until 8 a.m. Temperatures have dropped into the mid-30s, cold enough to harm unprotected plants and tender vegetation.
The National Weather Service in Huntsville warns that frost could linger in sheltered valleys and low-lying areas through sunrise. Residents are advised to cover outdoor plants or bring them inside. Once the early chill fades, sunshine quickly returns with highs rising into the mid-60s — a near-perfect setup for fall activities and trick-or-treat plans later in the day.
Saturday begins calm and mild, but clouds increase through the afternoon as a weak front approaches from the west. A 40 percent chance of rain develops late Saturday night into Sunday morning, mainly north of I-565. While rainfall totals will stay light, the system could bring damp roads and cooler air for early travel or outdoor events.
By Sunday afternoon, gradual clearing and a north breeze usher in drier conditions with highs around 58°F. The start of next week looks bright and warmer, with highs returning to the 60s and 70s under full sunshine — a comfortable start to November before the next stronger front late in the week.
For now, Huntsville sits at the classic fall crossroads: crisp mornings, short-lived showers, and a brief warm spell before the next chill returns.
