Isolated severe thunderstorms are possible from late afternoon Wednesday through early morning Thursday in southern Colorado to eastern New Mexico. Isolated damaging winds may occur across the eastern Midwest to Lower Great Lakes from mid-afternoon to evening. ....Eastern New Mexico into Southern Colorado... A southern-stream midlevel trough and accompanying speed maximum will move east-northeastward across the Southwest into the southern/central High Plains through the period. Preceding this feature, widely scattered thunderstorms will spread eastward from the Southwest to the central/southern High Plains from the afternoon into the evening/overnight hours. As thunderstorms advance/develop into eastern NM/southern CO, gradually increasing boundary-layer moisture (in response to the approaching wave) and diurnal heating should favor some increase in thunderstorm intensity. Around 40 kt of deep-layer shear will support a couple organized storms, capable of producing isolated large hail and severe wind gusts into the overnight hours. Farther south, additional thunderstorm development is possible over terrain features across the Trans-Pecos, given substantial boundary-layer moisture across the region. While moderate-strong buoyancy and favorable deep-layer shear would conditionally support isolated strong/severe storms, confidence in this scenario is currently low -- given lingering inhibition and a lack of larger-scale ascent. ....Eastern Midwest into the Lower Great Lakes... A trailing belt of moderate-strong midlevel southwesterly flow will overlie a weakening/stalling cold front extending across the region. Widely scattered thunderstorms will track east-northeastward along/immediately ahead of the front, where a weakly unstable air mass and around 30-40 kt of deep-layer shear will be in place. This will support a couple loosely organized storm clusters capable of producing locally damaging wind gusts during the afternoon and early evening hours. ...Weinman.. 06/02/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
