GREEN BAY, Wis. — A thick veil of fog wraps around the Fox River this early Sunday, the kind that softens streetlights and mutes the sound of traffic along U.S. 41. The air feels heavy and cold — just 29°F — as Wisconsin wakes to a calm, misty morning that will soon give way to sunshine and milder air.
Today’s pattern begins quietly. Fog lingers through early morning before skies gradually clear. Highs reach near 58°F, making it a welcome rebound after the chilly start. Light southeast winds build through the afternoon, offering one of the last truly mild stretches before a wetter, cooler midweek sets in.
By Monday, expect full sunshine and temperatures near 55°F, perfect for outdoor work or final yard cleanup before Halloween week turns damp. Conditions stay mostly clear through Monday evening, but clouds increase late, hinting at what’s ahead.
Tuesday brings the next shift, as a weak front slides into northeast Wisconsin. Scattered showers could begin by midday, with the best chance late in the afternoon and into Tuesday night. Rainfall looks light, but any drizzle could create slick spots on bridges and rural roads. Highs hover around 54°F, then dip into the low 40s.
The rest of the week trends cooler but manageable — partly sunny with small rain chances Wednesday and Thursday. Trick-or-treat conditions Friday look cool but dry, ideal for layered costumes under a clear autumn sky.
After all, the calendar’s turn is near — and a chilly November lies just ahead.
