Isolated storms could develop along a stalled cold front in southeast Nebraska this evening. And strong storms could move in from central Nebraska after midnight. Large hail and damaging winds are the primary threat. Due to heavy rainfall last night, localized areas could experience flooding. There is an enhanced risk for severe storms Tuesday afternoon and evening for southeast Nebraska and southwest Iowa. The stalled boundary near the Kansas and Nebraska border is expected to lift northward toward Interstate 80 as a warm front. Large hail and damaging winds would be the main threat Tuesday, along with isolated tornadoes. Points north and northwest of Interstate 80 would have a lower severe threat Tuesday. Otherwise, minor flooding will be possible near Seward on the Lincoln Creek, and from Wahoo to Ithaca on the Wahoo Creek. Flooding will also continue on the Missouri River downstream from Blair. .DAYS TWO THROUGH SEVEN...Tuesday night through Monday Minor to moderate river flooding will continue along the Missouri River from Blair south to Rulo. Other small rivers and streams will continue to run high. .SPOTTER INFORMATION STATEMENT... Spotter activation will probably not be needed tonight, but may be needed along and south of Interstate 80 on Tuesday afternoon and evening.
