St. Louis is waking up to light rain, sticky air and a stormy forecast Wednesday, with temperatures near 70 degrees early and a high around 79. Showers and thunderstorms are expected through the morning before activity gradually weakens later in the day.

Storms Ease Wednesday, Then Return Overnight

Widespread rain is expected Wednesday, with a few gusty winds and locally heavy downpours possible as storms move through the region. The shift is a sharp turn from Hoodline’s recent heat forecast, which had St. Louis flirting with 90-degree afternoons.

Rain chances drop during parts of Wednesday afternoon, but another round of showers and thunderstorms is expected late Wednesday night into Thursday. The National Weather Service says the strongest Thursday storms could produce isolated damaging wind gusts, though tornadoes appear unlikely.

A Cold Front Brings Windy Jacket Weather

Thursday could still reach 84 degrees, with storms likely early and additional showers possible through the afternoon. A cold front moves through early Thursday, bringing much cooler air and northwesterly flow.

Friday will feel like a different season, with a high near 61 and gusts of 30 to 35 mph. No watches, warnings or advisories are listed in the current forecast, but the gusty commute and rapidly falling temperatures will make a light jacket a smart addition.

Sunny Weekend Follows The Midweek Mess

The payoff arrives Saturday, with sunshine and temperatures in the mid-50s to low 60s. Sunday should bring sunshine and a high near 78, while Monday is forecast to reach a high near 72, followed by a high near 74 Tuesday.
