Missouri – A major pattern shift is underway this afternoon, with warmer air moving into the St. Louis region and setting the stage for several rounds of showers and thunderstorms that could impact travel over the next several days.
According to the National Weather Service in St. Louis, rain chances begin increasing late Thursday, with the highest coverage expected Thursday night into Friday when storm chances climb as high as 80%. This marks the start of a more active and persistent wet pattern.
Today remains relatively quiet, with highs in the low to mid-70s and dry conditions across the metro. Roads along I-64, I-44, and I-70 stay clear, offering smooth travel through the day.
By Thursday, scattered storms begin to develop, especially late in the day. Rain chances range from 20% to 30%, but conditions can change quickly after sunset as moisture deepens.
Friday brings the most widespread impacts. Rain and thunderstorms become likely across St. Louis, with periods of heavier downpours possible. Expect slick roads, reduced visibility, and slower commutes during peak travel times.
The unsettled pattern continues through the weekend. Saturday and Sunday both carry additional storm chances, though coverage becomes more scattered. Highs stay warm, generally in the upper 60s to near 80°F.
By Monday, rain chances increase again, with another round of showers and storms possible as temperatures climb into the low 80s.
Looking ahead, this warm and active pattern may persist into early next week, with repeated opportunities for rainfall and thunderstorms.
