Missouri starts the day under a hard winter grip as cold air presses across the St. Louis region. Frost clings to windshields, sidewalks crunch underfoot, and the chill lingers longer than many expect.
Temperatures early this morning sit near 18 degrees at Lambert International Airport, with light winds keeping wind chills in the teens. According to the National Weather Service, dry air dominates for now, limiting snow chances but allowing cold to settle efficiently. Any moisture left on roads from earlier periods can refreeze quickly after sunset.
Travel impacts remain limited this morning, though drivers should stay cautious on bridges, overpasses, and untreated side streets. Even small patches of ice can catch commuters off guard during the morning and evening drive.
Conditions improve slightly during the day. Sunshine helps highs climb toward 30 degrees, offering brief relief. The break is short-lived. Cold air strengthens again late Wednesday night into Thursday, with highs Thursday struggling near 20 degrees and lows dropping close to 2 degrees overnight. This creates a renewed risk for flash freezing, especially where melting occurs during daylight hours.
Friday remains cold, with highs near 15 degrees, before temperatures slowly rebound heading into the weekend. By Saturday, highs approach the upper teens, and by Sunday, readings climb into the mid-20s. While no major snow is expected locally, the persistent cold keeps winter hazards active.
Longer-range outlooks suggest a gradual moderation next week, though temperatures remain below seasonal averages across much of the central U.S. For now, winter remains firmly in control.
Bundle up, allow extra travel time after dark, and protect exposed pipes. How slick are roads where you live this morning?
