Scattered severe gusts (some 75+ mph) and large hail are probable across parts of central Nebraska this evening. Isolated severe gusts are also possible from the Upper Midwest to Utah and Wyoming through mid-evening. ...SD/NE... An organized linear MCS has become established from eastern SD into central NE.

Reference MCD #1679 and WW #514 for further details. ...Northern WY/Western Upper MI... A line of intense thunderstorms is tracking eastward along and south of the WI/Upper MI state line. These storms have produced sporadic damaging wind gusts over the last few hours, and are probably past-peak. Nevertheless, a few severe storms will remain possible for another 2-3 hours. Reference WW #513 for further details. ...WY... Scattered high-based thunderstorms continue to develop and spread across much of western and central WY. The strongest cells in this area will maintain some risk of damaging wind gusts for a few more hours until diurnal cooling diminishes the threat.
