Update 9:40 p.m.: The National Weather Service says the storms have weakened in the last hour or so, and it is in the process of canceling the remainder of the severe thunderstorm watch in the area.


Severe thunderstorms, with flooding rains and strong winds, are moving through the area where Nebraska, Kansas, Missouri and Iowa join.

Shortly before 8 p.m., the National Weather Service updated its storm forecast to advise that conditions were intensifying in the Midlands, raising the possibility of damaging winds and hail in the near term in southeast Nebraska. The threat is expected to subside as the evening wears on. This includes Sarpy and Douglas Counties.

The storm threat extends from northeast Kansas into northern Missouri and much of central and southwest Iowa. In Nebraska, the threat is largely in the far southeast corner of the state. Lincoln is outside of the severe storm watch, while Omaha is in it.

The greatest flash flood threat was in far northeast Kansas and a portion of northwest Missouri.

Separately, a wide swath of the southern U.S. from Texas and Louisiana up through southern Missouri was under a tornado watch, with numerous twisters reported on the ground throughout the afternoon and evening. Along this same corridor, there again was a significant flood threat.

Severe storm warnings were in effect in four locations at 7 p.m., and the National Weather Service had issued a flash flood warning for Interstate 29 between mile markers 71 and 85 — roughly that area where Doniphan County, Kansas, abuts Holt County, Missouri.

According to the weather service, radar indicated that up to 2 inches of rain fell this evening in the affected area. That is expected to lead to flash flooding, especially along low-lying rural roads.

Locations that may experience flooding include Mound City, Forest City, Maitland, Oregon and White Cloud. As of 7 p.m., the warning was to remain in effect until just after midnight.

The Omaha metro areas is under a severe thunderstorm watch until 1 a.m., so people will want to monitor conditions and listen to forecasts, given the potential for storms to materialize quickly. The primary threat is strong winds and hail.

Thunderstorms are expected across the region through tonight and the chance for storms continues Tuesday and again Thursday through Sunday, according to the weather service.

Strong storms have developed due east of the metro along the Pottawattamie-Mills County lines, southeast in Maryville, Missouri, and northeast near Denison.
