St. Louis, Missouri –Thunderstorms are expected to move across the Missouri-Illinois border early Monday afternoon, threatening to disrupt traffic and summer plans from St. Louis to Brooklyn along the I-55 corridor. Motorists and residents in the metro area should brace for sudden changes in weather and possible hazardous driving conditions during the midday hours.
According to the National Weather Service in St. Louis, a 50% chance of showers and thunderstorms develops after 1 p.m. Monday, July 14, with locally heavy rainfall and gusty winds possible. These storms could cause quick ponding on roadways, especially around St. Louis and across Madison County. If you hear thunder, move indoors immediately and delay outdoor activities until storms have safely passed.
Mostly cloudy skies will keep things muggy, with highs near 90°F and a humid summer feel. Patchy fog may develop Monday night, lowering visibility for late commuters and travelers near the river and throughout the border region. School programs, daycares, and businesses along both sides of the river should review their weather procedures and stay alert for rapidly changing conditions.
This pattern of scattered summer storms is typical for July along the Missouri-Illinois border, often developing quickly and producing intense, brief downpours. With a daily risk of thunderstorms through the workweek, it’s a good time for residents to make sure cell phones are charged and weather alerts are enabled.
Thunderstorm chances continue each afternoon through Friday, July 18. The National Weather Service may issue additional advisories or warnings as needed. Stay tuned for updates and allow extra travel time if storms roll through during your commute.
