Isolated strong, to locally severe, thunderstorms will persist for a few hours this evening. Damaging gusts are the primary concern. ....01z Update... Diurnal heating, and steepening of the boundary layer, has been the primary instigator for scattered convection across much of the CONUS this afternoon. Many areas have been efficiently overturned and with onset of nocturnal cooling, further stabilization is expected this evening. Even so, for the next few hours a few pockets of robust convection will likely persist. Moderate to strong buoyancy is noted across the Delmarva and the Red River region of southern OK/north TX. Deep convection may continue to generate locally strong winds until this activity weakens by mid evening. Isolated wind gusts may also accompany high-based convection across southeast AZ/southern NM, and near the OR/CA border. Boundary-layer cooling will also contribute to further weakening, along with a lessening severe threat. ...Darrow.. 07/01/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
