Heavy Rain Alert for Southern Plains and Central Regions 10-01 to 10-03
Updated Thu Oct 1st 2026, 6:13am PDT

Heads up, folks in the Southern Plains! On Thursday, expect showers and thunderstorms with a lot of heavy rain. The Gulf moisture is sticking around, and a front is merging into the region, which means that we could see heavy downpours. Be alert for flash flooding in your area, which might also affect larger rivers and cause debris flows in zones that have seen recent fires.

Rain Continues into Friday

Friday will see rain stretch from the Northeast down to the Ohio Valley. The Southern Plains will still deal with heavy rain showers, bringing more risk of flash flooding to urban areas and small streams. Keep a lookout as the rain continues to pour!

Weekend Showers Across Regions

Looking into Saturday, the showers will spread over the Central Gulf Coast, Lower Mississippi Valley, and Southern Appalachians. The Pacific Northwest will see a front move through, leading to rain by Saturday morning in the Northern Plains. The rain in these areas should mainly stay confined to small, localized areas.

For those in colder regions, expect rain instead of snow due to the current storm track and milder air temperatures.
