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.day-2_thumb

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.”
