Missouri – Warm air is rising fast across St. Louis, and you can almost feel the shift as clouds begin to thicken ahead of incoming spring storms.
According to the National Weather Service, storm chances increase steadily, with a 60% chance of showers and thunderstorms arriving by Friday afternoon. Some storms may bring brief heavy rain and lightning, especially along I-64, I-44, and I-70 corridors.
Across eastern Missouri and into southwest Illinois, including Belleville and Granite City, roads could turn slick quickly during heavier bursts. Visibility may drop during downpours, especially near the evening commute. Plan extra travel time and watch for ponding on roadways.
Today remains warm and mostly dry, with highs pushing into the low 80s. That warmth fuels instability heading into Friday. Conditions may deteriorate quickly after midday as scattered storms develop and expand.
The unsettled pattern lingers into the weekend. Saturday brings another 40% chance of showers and possible thunderstorms, mainly during the afternoon. By Sunday, storm chances continue at 30%, with clouds lingering across much of the metro area.
Early next week keeps the active spring pattern in place. Showers and thunderstorms become more widespread again by Tuesday, with rain chances climbing back to 60%. Expect periodic wet roads and slower commutes.
