St. Louis, Missouri – Rain chances are increasing across eastern Missouri and southwest Illinois on Sunday, with a few thunderstorms also possible as a cold front moves through the region.
According to the National Weather Service in St. Louis, the slower-than-previously-expected movement of a cold front has raised the likelihood of showers, now estimated at 50 to 70 percent, along with a 20 to 30 percent chance of thunderstorms. The change represents a relatively new forecast development.
Forecasters caution that confidence remains low regarding the coverage and potential strength of storms, due to the rapid evolution of the forecast and uncertainty surrounding the timing of the front. While some areas may see periods of steady rain, others could experience only brief or spotty showers.
The National Weather Service emphasizes that the forecast will continue to be refined as new data becomes available. Residents across the St. Louis metro area, including surrounding communities in eastern Missouri and southwest Illinois, are encouraged to monitor updates, especially if they have outdoor plans Sunday.
Those traveling or planning activities should be prepared for changing conditions and remain weather-aware as the cold front approaches.
