Sioux Falls, S.D. – Streetlights glisten against wet roads this early Tuesday morning as fog swirls through the valleys and a steady north wind builds. The damp chill signals a shift across eastern South Dakota as cooler, drier air sweeps in behind a departing storm system — and gusts could make travel tricky through early afternoon.
The National Weather Service reports rain will taper gradually today, with northwest winds increasing to 30–40 mph at times. Loose decorations, trash bins, and light outdoor items should be secured before mid-morning. Temperatures hold near 50°F through the day, dropping to the upper 30s by evening as clouds begin to thin.
Wednesday brings a quick rebound in sunshine and calmer conditions. Expect highs in the low 50s with lighter northwest breezes — a welcome break before temperatures dip again late week. Farmers and early commuters should plan for patchy morning frost, especially across open stretches west of I-29.
By Thursday, skies stay mostly sunny and highs climb slightly into the mid-50s. Halloween Friday looks brisk but dry, with daytime highs in the mid-40s and evening readings falling into the 30s — cool enough for heavier costumes or layers during trick-or-treat time.
The weekend brings partly cloudy skies and highs in the upper 40s to near 50°F — a classic early-November pattern that hints at bigger temperature swings ahead.
