Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0731 PM CDT Thu Sep 12 2019 Valid 130100Z - 131200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE MIDWEST... ...SUMMARY... Isolated severe thunderstorms will be concentrated across portions of southern Wisconsin and northern Illinois this evening. Other strong storms, with isolated severe wind gusts, will be noted from southeast Kansas - Oklahoma - Texas South Plains. ...01z Update... Strong short-wave trough is ejecting across the eastern Dakotas/Nebraska and will approach the upper Great Lakes region later tonight. Large-scale forcing for ascent is expected to influence ongoing convection currently located across WI - trailing into eastern IA. This activity should spread east over the next few hours with an attendant threat for mainly isolated severe wind gusts. Farther southwest, strong boundary-layer heating contributed to substantial buoyancy which led to thunderstorm development along the trailing wind shift across KS - northwest OK - southern TX Panhandle region. This activity is expected to propagate slowly southeast this evening and locally damaging winds will be the main threat. ..Darrow.. 09/13/2019 Read more
