THIS HAZARDOUS WEATHER OUTLOOK IS FOR MOST OF EASTERN NEBRASKA AND
PARTS OF SOUTHWEST IOWA.
THIS AFTERNOON AND TONIGHT…SEVERE THUNDERSTORMS ARE LIKELY THIS AFTERNOON AND THIS EVENING AS A POTENT STORM SYSTEM MOVES INTO THE CENTRAL PLAINS. SEVERAL
SURFACE BOUNDARIES WILL ADD TO THE COMPLEXITY IN STORM DEVELOPMENT TODAY. THE MAIN FOCUS FOCUS FOR POSSIBLE TORNADOES IS A WARM FRONT THAT IS EXPECTED TO BE LOCATED ACROSS SOUTHEAST NEBRASKA AND SOUTHWEST IOWA THIS AFTERNOON AND EARLY EVENING.
ABUNDANT LOW LEVEL MOISTURE…INSTABILITY AND STRONG SHEAR WILL BE IN PLACE CREATING A FAVORABLE ENVIRONMENT FOR SEVERE STORMS. A COLD FRONT WILL ALSO MOVE INTO THE AREA FROM THE NORTHWEST AND BE ANOTHER FOCAL POINT FOR THUNDERSTORMS THIS EVENING.
THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE THIS AFTERNOON. THE THREAT OF STORMS WILL CONTINUE INTO THE EVENING. ISOLATED TORNADOES…LARGE HAIL…DAMAGING WINDS AND HEAVY RAIN WILL BE THE MAIN THREATS.
In a update late this (Tuesday) morning, officials with the National Weather Service in Des Moines said “MAJOR rainfall likely for many tonight!” A widespread 2″ to 4″ of rain is likely for much of Iowa. This may lead to flash flooding and river flooding at many Iowa locations this evening into tomorrow morning. Locations from Atlantic eastward could see anywhere from 3-to 5-inches of rain during the period.
Anticipated rainfall over the next 24-hours. (NWS graphic) – click on image to enlarge.
Most flash flood fatalities occur at night because people cannot gauge the depth of the water. When in doubt, remember to turn around, don’t drown. A Flash Flood Watch is in effect for all but the far west and southwestern counties in Iowa, from 7-p.m. through early Wednesday morning.
