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 THIS AFTERNOON AND EVENING ACROSS PARTS OF INDIANA AND LOWER MICHIGAN...AND TONIGHT OVER PARTS OF IOWA SUMMARY Severe thunderstorms are possible this afternoon and tonight across multiple parts of the Midwest, as well as on a more isolated basis across the Gulf Coast, south-central Plains and northern Plains. IN/Lower MI Morning water vapor loop shows a strong and progressive Clipper system tracking southeastward across MN/WI. A band of clouds and isolated thunderstorms precedes this system, extending from southern Lower MI into central IL. While a few strong storms are possible to develop in this band, the greater risk for severe storms appears to be associated with a period of heating in the wake of these clouds. Steep lapse rates and cold temperatures aloft will combine with dewpoints around 60F to result in sufficient afternoon/evening CAPE for widely scattered strong/severe storm development. Large hail will be the initial main concern, along with some risk of a tornado or two. By early evening, damaging winds will be the main concern. IA Overnight The next in a series of fast-moving upper-level features will move across the Dakotas tonight, with large-scale forcing for ascent spreading into parts of MN/IA before 12z. This ascent will begin interacting with a plume of returning moisture, leading to scattered thunderstorm development in the pre-dawn hours. Elevated supercells capable of large hail will be the main risk through 12z. MT/ND The aforementioned upper feature will affect northeast MT and the Dakotas this afternoon and evening. A deeply-mixed boundary layer will develop over this area with temperatures in the 80s and 35-45F t-td spreads. CAPE will be rather weak, which should limit overall convective organization. Nevertheless, fast-moving high-based showers and thunderstorms capable of gusty and occasionally severe wind gusts are expected. Gulf Coast The tropical system (PTC 1) along the south TX coast is expected to slowly organize today, with widespread showers and thunderstorms from east TX into the central Gulf coast. Low-level winds are not particularly strong and forecast hodographs are only marginally favorable for updraft rotation. Nevertheless with such a broad area of risk, a tornado or two is certainly possible this afternoon through tonight.
