Marginally severe thunderstorms associated with hail and strong gusty winds will be possible across parts of the Intermountain West Sunday afternoon and evening. ....Intermountain West... A relatively high-amplitude system will move eastward from the West coast into the Intermountain West on Sunday. Ahead of the upper-level trough, a south-to-north corridor of instability will develop by afternoon across parts of eastern Nevada, western Utah and southern Idaho. As surface temperatures warm during the afternoon, scattered thunderstorms will form within a zone of large-scale ascent associated with the approaching trough. Although MLCAPE is forecast to peak between 500 and 1000 J/kg in most areas, mid-level lapse rates will be steep, peaking around 7.5 C/km during the late afternoon. This, combined with moderate deep-layer shear will be sufficient for a marginal severe threat. Hail will be possible with the more intense cores, and isolated wind damage may occur just ahead of or within the stronger downdrafts. ...Broyles.. 09/02/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
