St. Louis woke up under a gray ceiling Saturday, with temperatures parked near 30°F and a northwest breeze keeping things chilly. A few light snow showers or flurries may drift through through mid-morning, mainly south of Interstate 70, but forecasters expect little or no accumulation. By afternoon, highs should reach around 42°F, with skies trending partly cloudy for a more tolerable finish to the day.
Morning Commute
Drivers in south St. Louis County and along I-55 could see isolated light snow showers and brief slick spots through mid-morning. The National Weather Service keeps precipitation chances at roughly 20–30% in those areas, so most roads will be damp rather than dangerous. No watches or warnings are posted for the metro, but it is still smart to leave a few extra minutes if you are out early and to go easy on bridges and shaded stretches where temperatures hover near freezing.
Weekend Outlook
Sunday turns cooler and breezy, with a high near 35°F and northwest gusts up to 30 mph that will make it feel even colder than the thermometer suggests. Monday stays on the cool side, then a stronger southerly flow arrives Tuesday, bringing a noticeable warm-up with highs in the mid-50s and a shot at the 60s by Wednesday. Any winter feel looks short-lived and mostly confined to early Saturday, with a quick return to more springlike air by midweek.
City Preparedness
The City of St. Louis reports that crews have been pretreating primary snow routes and has published details on warming centers and emergency shelter options available to residents this weekend. See the City of St. Louis for full guidance. Officials urge residents to check local alerts before heading out and to call 2-1-1 if shelter assistance is needed. If precipitation ramps up, street crews will focus on main arterials and designated snow routes first.
Quick Tips
Layers are your friend this weekend, along with a fully charged phone and a little patience around plow and salt trucks. If you are driving farther from the city, a compact winter kit with a blanket, small shovel, and water is a solid backup plan. Otherwise, expect a mostly dry, cool couple of days, with a midweek warmup waiting in the wings to shake off the lingering winter vibe.
