Severe Threat Tonight Then An Extended Period Of Beautiful Weather

A Tornado Watch is in effect for Greater Nebraska until 11pm CT. Thunderstorms capable of producing large hail, damaging winds, heavy rain and isolated tornadoes are quite possible, and the storms will likely continue through the overnight.

An upper-level trough over the Intermountain West is grabbing lots of tropical moisture from Mexico and the Southwest and swinging it northeastward into the Central Plains. At the same time, a warm front that moved through most of Greater Nebraska today lies over northern Nebraska, while a surface trough extends from low pressure on the front over northwestern Nebraska southward through Panhandle Nebraska and into extreme eastern Colorado. These factors are combining to produce some potentially volatile weather tonight over Greater Nebraska. Lows will fall into the 60’s.

A cold front will move southeastward from Wyoming during Wednesday morning, and after some morning storms, especially over eastern areas, skies will begin to clear as gusty northwesterly winds bring in drier and cooler air. Highs will crest in the 70’s.

Then high pressure will gain control of our weather from Thursday night through early next week, with sunny skies and near average highs in the 70’s. A weak disturbance will get close to Greater Nebraska overnight Friday into Saturday morning, and it could set off a stray shower or storm, but dry weather will be the rule for several days after we get through our current round of stormy weather.

Stay tuned to KNOP-TV and log into KNOPNEWS2.COM and go to our WeatherActive Radar to follow tonight’s storms.
