United States evening weather update: flash-flood and severe-storm risks spread tonight
NOAA says flash-flood risk tonight centers on Montana and western South Dakota, with severe-storm potential in the central Great Plains and more flooding risk Sunday.
NOAA’s latest evening guidance points to an active weather setup across several U.S. regions tonight and Sunday, with flash-flood risk in the northern Plains, severe-storm potential in the central Great Plains, and another round of flood risk in parts of the Southeast. The main concern is how quickly conditions can change: heavy rain, rising water, hail, strong wind, and disruptive travel can develop fast enough to alter evening and Sunday plans.
Tonight’s highest-risk areas
The Weather Prediction Center says a Slight Risk of excessive rainfall remains in place across Montana into western South Dakota tonight, with the heaviest rain rates most likely in southeastern Montana, western South Dakota, and far northwest Nebraska. The discussion says the flash-flood risk should be localized, but it could still be intensified by backbuilding thunderstorms and a stronger overnight low-level jet.
Farther south, the Storm Prediction Center says storms from Nebraska into central Kansas can still produce large hail, severe winds, and possible tornado concerns as the evening goes on. The Weather Prediction Center also says those storms can dump enough rain to create scattered flash flooding, which means drivers may face both wind and water hazards in the same corridor.
Sunday’s next round of concern
By Sunday, NOAA’s flood outlook shifts attention to the Southeast. The Weather Prediction Center says a Slight Risk of excessive rainfall covers portions of the Southeast, with the update specifically pointing to southern South Carolina, southern Georgia, and northern Florida as areas where scattered flash flooding could occur if storms repeatedly move over the same ground.
The safest plan is simple: keep weather alerts turned on, leave extra time for travel, and do not drive through standing water or flooded roads. If you are headed outdoors tonight or Sunday in the affected regions, treat the forecast as flexible rather than fixed, because the highest-impact spots can shift quickly as storms develop.
