Severe Storm Risk
-There is a Slight 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 THIS AFTERNOON AND EVENING ACROSS PARTS OF EASTERN SOUTH DAKOTA...SOUTHWEST MINNESOTA...AND NORTHWEST IOWA THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE DAKOTAS INTO THE WESTERN GREAT LAKES...OVER THE SOUTHERN APPALACHIANS AND TENNESSEE VALLEY...AND OVER WESTERN KANSAS SUMMARY Scattered severe storms will be possible from the northern Plains into the Midwest and Great Lakes regions today into tonight, as well as across the southern Appalachians and Tennessee Valley this afternoon and early evening. SD to WI Morning water vapor imagery shows several weak and/or convectively induced shortwave troughs moving across the northern Plains into the Upper Midwest. This area will have widespread marginal to moderate afternoon CAPE and dewpoints in the 60s to lower 70s. This leads to a forecast of a large area of potential thunderstorm development, but with weak/nebulous forcing and general height-rises aloft. As such, the overall confidence in this forecast is not very high. Storms are likely to focus along a boundary currently evident from southern SD into central IA. Convection currently developing in northern IA near the boundary should continue to intensify through the afternoon and track into southern WI/northern IL with a severe wind/hail threat. Other intense thunderstorm clusters are expected to develop along the SD/NE portion of the boundary by mid/late afternoon, also with a risk of large hail and damaging wind gusts. Western KS Full sunshine and dewpoints in the 60s will lead to a region of strong instability over western KS this afternoon. Most CAM solutions suggest at least isolated thunderstorms form along the KS/CO border and spread slowly eastward during the evening. A deeply mixed boundary layer and sufficient CAPE suggest a risk of damaging wind gusts in the strongest cells. TN Valley/Southern Appalachians A widespread very moist and unstable air mass is present today across this region, with full sunshine leading to steep low-level lapse rates and MLCAPE values over 4000 J/kg. Weak forcing under an upper ridge limits confidence in timing/location of storms. However, widely scattered thunderstorm development should eventually result in merging outflows and the risk of gusty/damaging winds this afternoon and early evening across the region.
