Missouri–Illinois — Snowflakes swirl past downtown buildings while strong winds whip through the St. Louis metro this morning. Gusts rattle street signs and push cold air down the Mississippi River corridor.
A Wind Advisory remains in effect until noon across eastern Missouri and southwest Illinois, including St. Louis, St. Charles, Belleville, and surrounding communities. Northwest winds are gusting up to 55 mph, creating blustery conditions across the region.
Temperatures sit near 26°F early this morning, with wind chills dropping close to 10°F. Light snow continues in scattered bursts, briefly reducing visibility on highways.
Drivers traveling across Interstate 64, I-70, and I-55 should prepare for sudden gusts and drifting snow along open roadways. High-profile vehicles may experience stronger crosswinds.
Light snow gradually tapers later this morning, though winds remain gusty through midday. Any moisture on roads could freeze as temperatures stay below freezing.
The afternoon remains chilly with highs reaching only around 29°F. Sunshine slowly returns, but the air will still feel brisk as northwest winds continue.
Tonight brings calmer weather with partly cloudy skies. Temperatures fall to around 16°F, and lingering moisture may refreeze on untreated surfaces. Drivers should watch for flash freezing, especially on bridges and shaded streets.
A quiet stretch follows Tuesday with sunshine and highs near 37°F. However, a small system could bring a rain-snow mix Tuesday night before a dramatic warmup arrives midweek.
By Wednesday, March 18, temperatures surge into the mid-60s, signaling a sharp transition toward early spring weather.
