Isolated thunderstorms are possible along parts of the northern/central California coast on Friday. ...Synopsis... An upper trough oriented from the Great Lakes to the Gulf of Mexico will progress eastward toward the Atlantic coast on Friday. Meanwhile, the western upper ridge will shift east toward the Rockies and adjacent High Plains vicinity as an upper trough approaches the Pacific coast late in the period. Stable conditions and a dearth of boundary-layer moisture will preclude thunderstorm activity for most of the CONUS. However, deep-layer southwesterly flow ahead of the Pacific trough will support moistening midlevels along the CA coast. Somewhat cool midlevels and modest lapse rates will be sufficient for weak destabilization during the evening and overnight hours. Isolated thunderstorms will be possible along parts of the central/northern CA coastal vicinity, mainly after 00z. ..Leitman.. 12/27/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
