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 Read more View the full article Quote Link to comment Share on other sites More sharing options...
