St. Louis is waking up to clear skies and a crisp 50°F Friday morning, but the calm start is not sticking around all day. Mostly sunny conditions this afternoon are expected to give way to isolated showers by mid-afternoon, followed by scattered showers and thunderstorms later in the evening. The high should land near 77°F, with the main concerns being brief heavy downpours, lightning, and gusty winds in any stronger cells.
Afternoon And Evening
Isolated rain showers are possible roughly between 3 and 4 p.m., with scattered showers and thunderstorms becoming more likely through the late afternoon and evening. Daytime precipitation chances sit near 40%. According to the National Weather Service, a few stronger storms could produce small hail and gusty winds, although widespread severe weather is not anticipated. Keep an eye on radar, have a backup indoor plan, and be ready to head inside if thunder starts to roll.
Friday Night Into Saturday
Rain and storms are expected to linger into the early overnight hours, with showers likely before about 1 a.m. and temperatures dropping into the mid-50s. By Saturday, the pattern flips back to sunshine with a warm high near 81°F, offering a dry window for outdoor plans. This piece updates our storm timing forecast with more precise details for tonight's storms.
How To Prep
Bring a rain jacket and build in some extra time for the afternoon and evening commute, since quick downpours can cause ponding in low spots and reduce visibility. Transit riders should check for local service alerts before heading out, and anyone spending time outside should move indoors at the first rumble of thunder, because lightning can strike well ahead of the heaviest rain. Saturday is the payoff, so you can plan outdoor activities with confidence under sunny and warm skies.
