Heavy Rain and Flood Threat in the Central and Southern Plains 09-30 to 10-02
Updated Wed Sep 30th 2026, 4:27am PDT

This week, expect stormy weather with heavy rain and flooding risks, especially in the Central Rockies, Central Plains, and Southern Plains. Wednesday and Thursday will be particularly wet, with up to 2-3 inches of rain and a potential for flash floods. The rain may cause streams and rivers to overflow, impacting those in low-lying areas. Storms and showers will also reach the Upper Midwest and Great Lakes, with severe weather possible in parts of Texas and Oklahoma.

Heavy Rain and Flooding Concerns

Central Rockies/Central High Plains: On Wednesday, expect heavy rain due to a mix of upper-level energy and tropical moisture coming from the Gulf. Up to 3 inches of rain are expected, with potential for flash floods. Watch for swollen streams possibly affecting larger rivers.

Southern Plains: Wednesday will bring showers and thunderstorms, with a significant chance of flash flooding. Rainfall could reach 2-3 inches, creating hazardous conditions, especially in areas recovering from recent fires. Stay alert for urban flooding and avoid flooded roads.

Southern Plains: Thursday continues the risk of heavy rain, with ongoing potential for flash floods and river overflows, especially in burn areas.

Southern Plains: By Friday, the risk lessens slightly but localized flooding remains a threat. Be cautious in urban areas and near small streams.

Severe Thunderstorm Alert

Southern Plains: On Wednesday, severe thunderstorms could bring lightning, strong winds, hail, and even a few tornadoes. Stay safe and have your storm plans ready.

Rain Heading to the Midwest

Upper Midwest/Great Lakes: A cold front will bring rain and thunderstorms on Wednesday and Thursday. Expect additional rain for the Lower Great Lakes by Friday.

Gulf Coast/Florida Coast: Showers and storms will develop from Thursday to Friday, so keep your umbrellas close by.

The difference between rain and snow depends on the storm's path and where the cold air is located. In this case, warm air means rain for most areas.
