Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0736 PM CDT Mon Jul 13 2020 Valid 140100Z - 141200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL HIGH PLAINS AND MINNESOTA... ...SUMMARY... Severe thunderstorms are expected from the central High Plains into parts of the Upper Midwest tonight. Severe gusts, possibly significant, large hail and a couple of tornadoes are the threats with the stronger storms. ...01z Update... Large-scale 12hr mid-level height falls will spread across the northern Plains/Upper MS Valley tonight ahead of a pronounced upper trough. Early-evening vis satellite imagery suggests frontal cu field is deepening across western MN. With time scattered thunderstorms should develop south along this boundary before spreading east tonight. Large hail, damaging winds, and perhaps a few tornadoes remain possible. Farther south, deep convection is expanding across the central High Plains as it spreads east into a corridor of high instability characterized by 3000-4000 J/kg MLCAPE. Stronger updrafts will generate large hail, possibly in excess of 2 inches across western KS and southwest NE. Otherwise, damaging winds should become more common once a squall line emerges downstream. ..Darrow.. 07/14/2020Read more
