Missouri — A gray, chilly start greets the St. Louis region this morning. Temperatures hover near 29 degrees, and light sprinkles or flurries drift through the air. The cold bites early, and damp pavement may briefly glaze over on bridges and overpasses.
The good news arrives quickly. Clouds thin later today, and temperatures rebound toward 40 by afternoon. Any early flurries fade fast, but slick spots remain possible early, especially on untreated roads and shaded ramps. Drivers should ease off the gas during the morning hours.
Sunday brings a calmer feel. Sunshine mixes with clouds, and highs climb into the low 40s. Winds stay light, making it feel noticeably better than the past few mornings. By Sunday night, skies clear and temperatures settle near the freezing mark.
The real shift unfolds Monday. Meteorologists are tracking a strong warming trend as southerly flow strengthens. Afternoon highs surge into the upper 50s, possibly touching 60 in parts of the metro. Coats feel optional by midday, a sharp contrast to the weekend chill.
Travel conditions improve steadily through Monday, though the rapid warmup can create patchy moisture on roads early. Watch for brief fog or damp spots near rivers and low-lying areas.
Tuesday pushes even warmer. Highs soar into the low 60s under mostly sunny skies. This warmth signals a quiet start to the first full workweek of 2026, though rain chances return later in the week.
For now, winter loosens its grip. Keep layers handy this morning, then prepare for a springlike flip by Monday.
