ST. LOUIS – No widespread fog to worry about Wednesday morning, though the river valleys may see some formation around daybreak. Our weather story becomes the heat, as above-average temperatures move in.
Average highs for mid-May are in the mid-70s. We’ll be 10 to 15 degrees warmer Wednesday through Friday. A sunny start Wednesday then more clouds and a bit breezy in the afternoon. The temperature is expected to peak in the mid-80s.
It will be mostly clear overnight, with wake-up temperatures in the upper 60s. Thursday will be breezy and hot; afternoon temperatures will push to around 90 F. The record high is 94 F. There is only a slight chance of experiencing an afternoon pop-up shower or storm.
Highs near 90 F again Friday, with thunderstorms expected Friday evening. Some of these storms could be on the strong side, with hail being the main concern. Be ready to adjust Friday evening plans. Not as warm Saturday behind the storms, though still above average, with highs closer to 80 F.
