St. Louis is in for a sticky, stormy Thursday, April 2, 2026, with cloudy and humid conditions, temperatures in the mid-60s this morning, and a climb to a high near 77°F. Showers and thunderstorms are most likely this afternoon, with the most intense window between 1 p.m. and 4 p.m. Brief but heavy downpours could slow the evening commute and cause ponding on low-lying streets.
Afternoon Storms
Storms are expected to ramp up in coverage through the late afternoon and evening, with roughly an 80% chance of precipitation during the peak period and pockets of very heavy rain. There is also a risk for severe storms in parts of the region today and Friday, including damaging winds and isolated tornadoes, according to the National Weather Service St. Louis.
What To Expect
Drivers should be ready for sudden drops in visibility in heavier showers and localized street flooding, so it is worth budgeting extra travel time this afternoon and evening. Stronger gusts could snap small branches and trigger a few scattered power outages, so it is a good idea to secure loose outdoor items and keep phones and other devices charged. If a severe thunderstorm warning is issued, the safest move is to head indoors and stay away from windows until storms pass.
Afternoon Winds Pick Up
The National Weather Service has issued a Wind Advisory from noon to 7 p.m. CDT on Thursday, April 2, 2026, calling for south winds of 20 to 30 mph with gusts up to 45 mph, according to the National Weather Service. Gusty conditions could make driving tricky for high-profile vehicles and may toss around unsecured yard items, and maintenance crews may be clearing downed limbs into the evening. It is worth checking for any new advisories or warnings before heading out.
Looking Ahead
Showers and thunderstorms could linger into tonight and redevelop on Friday before a cold front moves through and brings in cooler, drier air for the weekend. Highs are expected to fall into the 60s by Saturday. If you have outdoor plans, it is smart to keep them flexible and stay tuned for updated forecasts.
