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 ACROSS THE NORTHERN HIGH PLAINS THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE TENNESSEE VALLEY TO THE CAROLINAS SUMMARY Severe thunderstorms are likely today across the northern High Plains including northeast Wyoming and eastern Montana into the western Dakotas, with storms capable of very large hail, very strong outflow winds (80+ mph), and tornadoes late this afternoon into tonight. 20Z Update The previous forecast remains on track, and only minor adjustments were made with this update. The ENH risk was expanded slightly southwestward in northeastern WY, where several discrete supercell have evolved off the Bighorn Mountains -- posing a risk of large to very large hail. In western ND, the CIG1 tornado area was extended slightly northward. Continued diurnal heating amid upper 60s dewpoints will yield moderate-strong surface-based buoyancy and minimal inhibition. Backed surface winds beneath strengthening flow aloft will contribute to favorably curved hodographs. Any storms that can form or move into this environment will conditionally support a strong tornado. Farther east, the SLGT risk was expanded northward in the lower OH Valley. Here, diurnal heating/destabilization of a very moist air mass (upper 70s dewpoints) will continue to support loosely organized thunderstorm clusters capable of producing widely scattered damaging winds this afternoon.
