St. Louis is starting Wednesday, May 20 under a blanket of low clouds and a chill in the air. Morning temperatures are sitting in the mid-50s (around 57°F), with a chance of light rain before 9 a.m., and a cool daytime high near 68°F on tap. A steady northeast breeze around 7 to 9 mph will keep things feeling crisp for the commute.
Today and Tonight
Showers are possible through the early morning hours, mainly before 9 a.m., then the rest of the day stays mostly cloudy with that high near 68°F. Tonight, expect more clouds overhead and a low near 53°F.
The quiet, cool stretch does not last long. Late Thursday night into Friday, the pattern turns wetter, with showers and thunderstorms likely Friday and highs near 73°F. Storm chances stick around through the Memorial Day weekend as temperatures climb back into the 80s. According to the National Weather Service St. Louis, parts of the region face an elevated risk of heavier, potentially training downpours late this week.
Planning Ahead
If your Memorial Day plans involve a grill, a park, or a festival, it is a good idea to build in a rain plan or front-load outdoor activities earlier in the day when possible. Many events will be watching the radar closely and could adjust schedules if thunderstorms move in. For a broader look at how this week shapes up, check out the earlier forecast.
Commute Tips
Where showers develop this morning, roads could be a bit slick, especially on bridges and overpasses. Give yourself extra time, keep the umbrella close, and take it easy on the accelerator. Before you head out, a quick check of the latest forecast can help, since the timing and intensity of any storms could still shift if the system organizes differently overnight.
