Hazardous Weather Outlook National Weather Service Omaha/Valley NE 352 AM CDT Tue May 28 2019 IAZ043-055-056-069-079-080-090-091-NEZ011-012-015>018-030>034- 042>045-050>053-065>068-078-088>093-282300- Monona-Harrison-Shelby-Pottawattamie-Mills-Montgomery-Fremont- Page-Knox-Cedar-Thurston-Antelope-Pierce-Wayne-Boone-Madison- Stanton-Cuming-Burt-Platte-Colfax-Dodge-Washington-Butler- Saunders-Douglas-Sarpy-Seward-Lancaster-Cass-Otoe-Saline- Jefferson-Gage-Johnson-Nemaha-Pawnee-Richardson- 352 AM CDT Tue May 28 2019 This Hazardous Weather Outlook is for portions of southwest Iowa...west central Iowa...east central Nebraska...northeast Nebraska and southeast Nebraska. .DAY ONE...Today and Tonight Severe thunderstorms are possible through tonight. Storms moving west to east across southeast Nebraska in the early morning could produce hail and strong winds. Then another round of thunderstorms is forecast to fire just after noon, mainly affecting southeast Nebraska initially, then spreading north and east into southwest Iowa. Hail, damaging winds are possible over much of eastern Nebraska and western Iowa. However there is a risk for tornadoes generally in far southeast Nebraska and far southwest Iowa, generally south of a line from Red Oak to Weeping Water to Beatrice. Also, heavy rain is likely from storms through tonight. Several rounds of storms are expected to affect areas from the Omaha Metro to the east and south. Thus a Flash Flood Watch has been issued for those areas where soils are already saturated and an additional 1 to 3 inches of rain could lead to Flash Flooding. In addition to the risk of flash flooding, river and creek flooding is likely in many areas, especially in southeast Nebraska and southwest Iowa to include the Missouri River from Blair downstream to past Rulo. .DAYS TWO THROUGH SEVEN...Wednesday 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 may be needed along and south of Interstate 80 on this afternoon and evening.
