Prepare for a wild weather ride! Missouri and Illinois are expected to see a dramatic mix of rain, possible snow, and a complete turnaround with sunshine by Sunday.
The fast-moving system will bring showers on Friday, with the possibility of a brief burst of snow overnight, before returning to warmer, more pleasant conditions just in time for the weekend.
If you plan to travel, be prepared for slick roads early Saturday morning, particularly in northern areas where temperatures will fall below freezing. Fortunately, sunshine will return by Saturday afternoon, melting away any remaining winter weather. Here is what to expect.

St. Louis, MO:
- Cloudy with scattered rain showers in the afternoon.

Friday Night into Saturday: A Quick Taste of Winter?
