As a series of storms moved across the St. Louis area on Friday, First Alert 4 viewers submitted photos and videos capturing the extreme weather conditions.

Why it matters

Severe weather events can pose significant risks to public safety, infrastructure, and property in the St. Louis region. Sharing real-time updates and visuals from community members helps provide a more complete picture of the storm's impacts and allows officials to better coordinate emergency response efforts.

The details

The storms developed earlier than expected, with isolated cells forming in the afternoon despite a low initial chance of severe weather. A subtle disturbance helped trigger these initial storms, which brought a threat of hail and isolated tornadoes. A more widespread line of storms is then expected to move through the metro area between 8 PM and 3 AM, potentially bringing damaging winds and brief tornado touchdowns, though the storms may weaken somewhat after sunset.
