St. Louis is waking up to mostly clear skies and crisp air this Saturday, April 11, with temperatures sitting at about 48°F at 5:40 a.m. CDT. A warm front is set to nudge those readings into the mid 70s by this afternoon, with a high near 74°F expected. There is a slight chance of a few scattered showers late in the day, so it is not a bad idea to keep an umbrella in the car for any late afternoon or early evening plans.

Afternoon Shower Chance

According to the National Weather Service St. Louis, a slight chance of rain showers moves in after 3 p.m. Saturday, April 11, with precipitation chances around 20 percent and any rain expected to be brief and spotty. The atmosphere today favors light, short lived showers instead of a solid line of storms, so severe weather is not anticipated this afternoon. East to southeast winds around 8 mph will keep things mild and just a touch on the muggy side.

Breezy Sunday

Sunday, April 12 is on track to feel more like early summer, with highs near 83°F and south winds of 8 to 17 mph. Gusts could push into the 30 mph range in the afternoon, which means patio chairs, trash can lids, and lightweight lawn decor may decide to go for a walk if they are not tied down.

Next Week Outlook

The active pattern ramps up as the workweek starts, with highs climbing into the mid 80s Monday, April 13 and potentially the upper 80s by Tuesday, April 14. Each afternoon and evening carries at least some chance for showers and thunderstorms. The National Weather Service St. Louis currently flags Wednesday, April 15 as the most likely day for stronger or possibly severe storms, although the exact timing and coverage are still uncertain. It is worth checking updated forecasts before making midweek outdoor plans and knowing in advance where you would go if a warning is issued for your neighborhood.
