Missouri starts the morning under a hard winter edge, where breath hangs in the air and pavement creaks under cold pressure. The chill feels sharper than the thermometer suggests, especially before sunrise.
Across the St. Louis metro, temperatures hover near 9 degrees, but wind chills drop between 10 and 15 degrees below zero. The National Weather Service has issued a Cold Weather Advisory through mid-morning, urging caution for anyone outdoors. Even light winds pull heat fast from exposed skin.
Sunshine builds later today, and highs climb toward 30 degrees, but the cold never fully loosens its grip. Side streets stay stiff, shaded sidewalks remain slick, and vehicles respond slower in the cold. Plan extra time if commuting early.
Tonight stays cold but calmer. Lows settle near 10 degrees, allowing frost to reform on untreated surfaces. Bridges and overpasses cool fastest, increasing the risk of hidden slick spots by early Thursday.
Thursday trends mostly cloudy with highs near 22 degrees. The air feels quieter, but the cold persists. Friday turns colder again, with highs near 16 degrees, reinforcing winter’s hold across eastern Missouri and southwest Illinois.
Saturday brings only modest improvement. Sunshine returns, but highs stay near 18 degrees, keeping conditions brisk for outdoor plans. Any snowpack from previous systems remains locked in place.
By Sunday, attention shifts to a small chance of snow during the afternoon, with highs near 27 degrees. While amounts appear light, even brief snow can reduce visibility and create slick roads, especially with cold ground temperatures.
Looking ahead, early next week trends milder, with highs reaching the lower 30s, though winter remains very much in control.
Dress in layers today, limit prolonged outdoor exposure, and watch for flash freezing where daytime melting refreezes after dark. Traveling later this week or Sunday? Let us know what road conditions look like where you are.
