Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Dec 28 2023 06:46:57 ACUS02 KWNS 280646 SWODY2 SPC AC 280645 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1245 AM CST Thu Dec 28 2023 Valid 291200Z - 301200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible along parts of the northern/central California coast on Friday. ....Synopsis... An amplified upper pattern will persist over the CONUS on Friday with a trough slowly migrating across the eastern U.S., while an upper ridge shifts east across the Intermountain West/Rockies. The main feature of interest with regards to thunderstorm potential will be an upper trough over the eastern Pacific, shifting east toward the Pacific coast late in the period. Deep-layer southwesterly flow ahead of the trough will bring increasing low- and mid-level moisture to coastal CA. Steepening midlevel lapse rates via cooling aloft will be sufficient for the development of weak instability Friday night/early Saturday morning. Isolated lightning flashes will be possible along the northern and central CA coast, mainly after 00z. Severe storms are not expected. Dry and stable conditions across most of the rest of the CONUS will preclude thunderstorm potential. ...Leitman.. 12/28/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
