St. Louis, Mo. – Missourians should stay weather-aware Friday afternoon as a cold front sweeps across the state, bringing the potential for damaging thunderstorms before a much cooler and wetter weekend settles into the region.
According to the National Weather Service in St. Louis, scattered showers and thunderstorms will move west to east during the morning, followed by a stronger round of storms developing between 3 p.m. and 9 p.m., with the greatest severe weather threat focused across Missouri. The primary hazards include damaging straight-line winds, locally heavy rainfall, and the possibility of one or two brief, weak tornadoes.
Communities including St. Louis, Columbia, Jefferson City, Rolla, Farmington and surrounding areas should be prepared for rapidly changing weather during the afternoon and evening commute. Strong wind gusts could bring down tree limbs, cause isolated power outages and create hazardous travel conditions. Heavy downpours may also lead to localized ponding on roads and reduced visibility.
Residents planning outdoor activities Friday afternoon should closely monitor weather updates and have multiple ways to receive warnings. If a Severe Thunderstorm Warning or Tornado Warning is issued, move indoors immediately and avoid travel during the strongest storms if possible.
Behind the front, a noticeably cooler pattern arrives for the weekend. Saturday will feature on-and-off rain showers with highs near 75 degrees, while scattered showers may linger across southeast Missouri and southwest Illinois on Sunday with highs around 80 degrees. Dry weather returns Monday with temperatures climbing back into the lower to middle 80s before warmer, more humid conditions rebuild across the region by the middle of next week.
