St. Louis – Heavy overnight rain and thunderstorms saturated the region early Thursday, prompting flash flooding in several counties south of the city.
Flash Floods Mark Soggy Thursday Dawn
Storms trained over southeast Missouri counties overnight, dumping 2 to 4 inches of rain in Ste. Genevieve, St. Francois, Madison, and Perry counties.[1] This led to flash flooding where rainfall concentrated most intensely. Rain continued shifting eastward out of the area through the morning hours.
Dense fog formed north of St. Louis in zones spared the heaviest precipitation. That fog could drift southward as drier air infiltrates by daybreak. Conditions improved steadily thereafter, offering residents a respite from the downpours.[1]
Thursday Afternoon Brings Clearer Skies
A break from the wet weather dominated the latter part of Thursday. Clouds thinned enough for occasional sun to emerge. High temperatures climbed into the 60s across the metro area.
A slim possibility lingered for isolated showers or storms along and north of Interstate 70 late Thursday. Still, most locations stayed dry, allowing puddles to recede and roads to recover.[1]
Friday Delivers Warm, Breezy Respite
Friday promised the warmest day of the week so far. Dry conditions prevailed under breezy skies. Afternoon highs pushed well into the 70s, a notable jump from Thursday’s milder readings.[1]
Winds picked up, adding a crisp feel despite the mercury’s rise. This setup provided ideal weather for outdoor plans before evening changes. Residents could enjoy the temporary calm after the prior night’s chaos.
Severe Storms Threaten Friday Evening
A cold front approached Friday night, ushering in new rounds of storms. Some carried potential to intensify into strong or severe events. The greatest risk concentrated west of St. Louis, where instability built ahead of the boundary.[1]
Forecasters urged vigilance as damaging winds, hail, or isolated tornadoes remained possible in the strongest cells. Timing focused on late evening into overnight hours.
Weekend Starts Wet but Clears Quickly
Showers and storms greeted early Saturday risers. However, the system moved out rapidly, yielding to drier air. Sunshine returned for the latter weekend, breaking the recent wet pattern.
Temperatures moderated into comfortable ranges, supporting typical March activities. The forecast hinted at sustained improvement through Sunday.
| Day | Conditions | High Temp |
|---|---|---|
| Thursday | AM wet/foggy, PM partly sunny | 60s |
| Friday | Dry, breezy, warm | 70s |
| Saturday | AM showers, then sunny | Mild |
Key Takeaways:
- Flash flooding hit southeast counties with 2-4 inches of rain overnight.[1]
- Friday highs reach the 70s before severe storm potential Friday night.
- Weekend improves with quick drying Saturday morning.
