Red Area for Monday, May 9, 2016

Severe Thunderstorm Risk Outline

 

Strong to Severe Thunderstorms Possible for Central Plains

From North Texas through Central Oklahoma and Eastern Kansas, the severe weather potential will be somewhat conditional depending on where the dryline sets up. If the dryline sets up further to the west, large hail and damaging winds will be the primary threats with a few tornadoes possible; if the dryline sets up further to the east, the thunderstorm risk would be reduced significantly. Meanwhile, to the north across the Mid-Mississippi Valley and portions of the Northern and Central Plains,  thunderstorms capable of large hail and damaging winds will be possible. In addition, locally heavy rainfall will be possible; rainfall accumulations of 1-2 inches with locally higher amounts in excess of 3 inches will be possible in some locations.
