Isolated thunderstorms will be possible across the Four Corners today and along the northwest Gulf coast late tonight. ....Synopsis... A progressive shortwave trough will move eastward over the Four Corners today, with the threat for isolated thunderstorms in association with steep midlevel lapse rates and a few hundred J/kg of SBCAPE. Farther east, air mass modification and return flow is underway across the western Gulf of Mexico, in response to lee cyclogenesis across southwest KS. The northwest Gulf coast will likely remain capped until the very end of the period, when low-level moistening and warm advection may become sufficient for isolated/elevated thunderstorms in warm sector confluence bands. ...Thompson/Lyons.. 12/28/2022 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
