There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS AND THE CAROLINAS SUMMARY Severe thunderstorms are expected mainly tonight across the Dakotas. Large to very large hail and severe winds are the primary hazards. Thunderstorms capable of scattered wind damage are possible in parts of the Carolinas. 20Z Update The SLGT risk in eastern IA was removed, given recent convective trends and displacement from the parent/weakening MCV. The MRGL risk in the wake of this activity was also trimmed in parts of the Midwest, where robust capping at the base of the EML will limit thunderstorm/severe potential. Farther west, the SLGT risk in the northern Plains was expanded slightly southwestward in southwest SD, where steepening midlevel lapse rates and around 60 kt of effective shear will promote large hail with intensifying elevated supercells overnight.
