THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 60 STATUTE MILES EAST AND WEST OF A LINE FROM 45 MILES SOUTH OF CHANUTE KANSAS TO 40 MILES EAST NORTHEAST OF SHENANDOAH IOWA.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

REMEMBER…A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY DO PRODUCE TORNADOES.

Meteorologists are warning residents of the Midwest to stay pay close attention to the forecast for Mother’s Day. The Severe Storms Prediction Center in Norman, OK., says a severe weather outbreak with many tornadoes and very large hail is possible Sunday and Sunday night across parts of the central plains and mid-Missouri valley. Persons celebrating with loved ones and those attending graduations should be aware of a potentially explosive outbreak of severe weather. Much if Iowa, especially southwest and west central parts of the state, fall under the “Moderate” risk category.

Officials with the Iowa Storm Chasing Network say “Of particular concern here in Iowa is the conditions which will favor the development of a few, independent supercells, rather than a more linear bowing structure of storms.  This setup gives us concern that not only are tornadoes possible, but strong, long-track tornadoes as well.”
