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 AN ENHANCED RISK OF SEVERE THUNDERSTORMS PARTS OF EASTERN NORTH DAKOTA AND NORTHWESTERN MINNESOTA SUMMARY Severe thunderstorms are expected today across the Dakotas, Upper Midwest and Middle Missouri Valley, including damaging winds, large hail and a few tornadoes this afternoon through tonight. 20Z Update The most noteworthy change with this update was the addition of 10-percent tornado probabilities (with CIG1) over parts of eastern ND into northwestern MN. Here, the latest surface observations and visible satellite imagery indicate a warm front moving slowly northward. In the wake of an earlier MCS, diurnal heating of a moist air mass (lower 70s dewpoints) and steep midlevel lapse rates should yield sufficient boundary-layer recovery for the development of surface-based storms ahead of a surface low tracking northward across the Dakotas this afternoon and evening. Related strong buoyancy (3000-4000 J/kg MLCAPE) and increasingly large clockwise-curved hodographs (200-300 m2/s2 effective SRH) near the boundary will support a locally favorable corridor for a few supercell tornadoes (some of which could be strong).
