710 ACUS01 KWNS 190100 SWODY1 SPC AC 190058 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0758 PM CDT Wed Sep 18 2024 Valid 190100Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER A NARROW ZONE FROM THE NORTHERN PLAINS AND UPPER MISSISSIPPI VALLEY INTO THE CENTRAL PLAINS... ...SUMMARY... Isolated strong storms are possible this evening over parts of the central Plains, and from the Red River into the upper Mississippi Valley overnight. ...Northern Plains/Upper MS Valley... Cooling aloft with an upper trough will continue eastward across the Dakotas and into MN, with a cold front pushing east and providing a focus for possible storm development. Convection is now forming within a narrow instability axis over eastern ND, and some of the cells could eventually produce severe hail. Additional activity may occur farther south as well, although coverage is less certain. Cool air aloft with veering winds with height will tend to favor sporadic hail. For more information see mesoscale discussion 2085. ...Central Plains... Warm temperatures and peak heating has led to isolated storms along a retreating dryline from south-central KS into the eastern TX Panhandle. While capping should eventually result in dissipation in a couple hours, marginal hail or locally strong gusts will be possible in the near term. ..Jewell.. 09/19/2024 $$
