After a year-long review of new ground survey data and aerial imagery, NWS St. Louis made several adjustments to the May 16, 2025 tornado damage assessment. Read More >

Severe Risk: This Afternoon/Overnight

Tuesday Severe Thunderstorm Risk

Thunderstorms will continue across the area this afternoon and evening. Along and south of I-70 a few thunderstorms may become severe, capable of 60 mph winds, quarter-sized hail and a brief tornado or two. Overnight a mass of thunderstorms will drop south through the region, bringing more rain to the region. The risk for flash flooding will continue overnight, the main threats are flooded roadways, particularly in low-lying and urban areas across the green area in the map (Flood Watch).

Another round of severe thunderstorms is expected Tuesday afternoon across portions of central, east-central, and southeast Missouri and southern Illinois. How strong thunderstorms are depends on how much lingering rain and cloud cover we see Tuesday morning. Less clouds will result in a higher and more widespread severe risk, while more clouds will keep thunderstorm ingredients lower, reducing the severe risk and keeping it further south. Wherever severe thunderstorms form, damaging winds and large hail are the main threats.
