St. Louis is bracing for a chance of light snow this afternoon, with the National Weather Service forecasting a 20-40% chance of flurries after noon. While accumulations are expected to be light, generally under a half inch, the wintry mix could make for slick conditions on untreated roads and bridges as temperatures hover near the freezing mark.

Why it matters

Even light snow can create hazardous driving conditions in the St. Louis area, especially on secondary roads that may not be prioritized for plowing and salting. This could impact the afternoon and evening commute, making travel treacherous for residents.

The details

The snow showers are expected to move through the region mid- to late afternoon, potentially reducing visibility and traction on the roads. The Missouri Department of Transportation notes that crews will focus first on interstates and major arteries, so side streets and neighborhood routes may stay messy longer. Drivers are urged to use caution, reduce speeds, and leave extra room for plows and salt trucks.

  • The best chance for light snow will be from mid-afternoon to early evening on Sunday, February 1, 2026.
  • Flurries could linger until around 10 p.m. on Sunday before tapering off overnight.
  • Temperatures are expected to reach the upper 20s Fahrenheit on Sunday afternoon.
