Severe wind gusts and isolated large hail are the primary hazards. Southern/central High Plains A storm cluster is moving southeastward across the TX/OK Panhandles this evening. A short-term threat for strong to severe gusts will persist through the evening with this cluster. The evolution of this cluster as it moves into a region influenced by westward-moving outflow is unclear. Cooler temperatures and weaker low-level lapse rates are observed within this outflow, though richer low-level moisture and stronger MUCAPE also noted, which may help to sustain the ongoing cluster and an attendant severe-wind threat through the evening. Farther north, widely scattered strong to severe storms are ongoing across parts of the central High Plains. Moderate buoyancy and effective shear of 30-40 kt will continue to support a threat of isolated hail and localized strong to severe gusts through dusk. Increasing CINH should eventually lead to a weakening trend later tonight, though any storm clustering this evening could lead to a longer duration of localized severe-wind potential. See MCD 2132 for more information regarding the short-term threat in this area. Parts of WI/Upper MI Occasional strong to severe storms have been noted within a storm cluster across northwest WI this evening. MLCAPE of 1000-2000 J/kg and 30-40 kt of effective shear largely orthogonal to the surface front/trough will continue to support supercell potential through dusk, before a gradual weakening trend is expected. See MCD 2133 and WW 626 for more information.
