Missouri — Cold air presses down on the region as gray clouds hang low over the Mississippi River. The pavement looks dry for now, but the air bites exposed skin. Winter is firmly in control across eastern Missouri and southwest Illinois.
Light snow is expected at times this evening, mainly across east-central Missouri and nearby Illinois counties. Most locations see little accumulation, though a narrow band could pick up up to one inch. Even light flakes may briefly reduce visibility on bridges and untreated roads.
According to the National Weather Service in St. Louis, the bigger concern arrives this weekend. Bitter cold settles in, with dangerous wind chills Saturday morning and again Sunday morning. Gusty north winds will push apparent temperatures close to zero, especially before sunrise.
Today stays mostly cloudy, with highs near 18 degrees. Flurries may develop this afternoon, then taper this evening. Tonight turns sharply colder as skies gradually clear. Temperatures drop into the single digits, setting up a hard freeze.
Saturday remains cold and mostly sunny, but warmth never arrives. Highs struggle near 19 degrees. Winds stay brisk, keeping conditions uncomfortable outdoors. After sunset, temperatures plunge again, reaching around 3 degrees by early Sunday.
Sunday offers more sun and slight improvement. Highs climb toward 30 degrees, though the morning remains harsh. Cold lingers into early next week, with only gradual moderation by Monday and Tuesday.
Drivers should watch for flash freezing, especially where light snow melts during daylight. Side streets, overpasses, and ramps may turn slick quickly after sunset. Dress in layers, limit exposure, and check on vulnerable neighbors.
Another chance for light wintry precipitation appears midweek, keeping winter impacts in play across the region.
