Missouri and western Illinois are waking up to a sharp winter chill across the St. Louis metro. Temperatures are sitting at 19 degrees at Lambert International Airport late this morning. Wind gusts earlier pushed chills down near 4 degrees, biting and uncomfortable.
Sidewalks and secondary roads remain slick in spots after the early freeze. Drivers along I-64, I-44, and I-70 should watch for patchy icy stretches, especially on bridges and ramps. Late February often brings flash-freeze risks when daytime melt refreezes after sunset.
Skies gradually turn sunnier today, helping temperatures rebound. Highs reach near 34 degrees this afternoon. The sunshine feels better, but the air still carries a winter edge.
Tonight turns mostly clear with lows around 22 degrees. A dramatic shift arrives Tuesday. Highs surge to near 53 degrees under partly sunny skies. Southwest winds increase, adding a mild feel by afternoon.
Wednesday stays mostly sunny with highs again near 53 degrees. Clouds thicken Wednesday night, and rain becomes likely after midnight. A few rumbles of thunder cannot be ruled out. Lows settle near 38 degrees, keeping precipitation mainly liquid.
Thursday brings a 40 percent chance of rain early, then partial clearing with highs near 49 degrees. Friday looks even milder, with sunshine and highs climbing into the lower 60s. That’s well above average and a strong hint of spring warmth.
The 6- to 10-day outlook favors above-normal temperatures across the Midwest, signaling a warming trend into early March.
