Administrators NorthGeorgiaWX Posted December 28, 2023 Administrators Share Posted December 28, 2023 SPC 1730Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1124 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 and Discussion... An amplified upper-air pattern will exist on Friday, with a large upper trough and low over the eastern CONUS, and a ridge over the West. Another upper trough will affect the West Coast, bringing cooling aloft and increasing midlevel moisture. Weak elevated instability may support sporadic lightning flashes within the warm advection zone preceding the cold front from northern CA into western OR, with further destabilization taking place overnight as the cold front approaches the Coast. The greatest threat of isolated thunderstorms will be after 06Z, coincident with the coolest temperatures aloft. Forecast soundings show little if any threat of severe weather, given weakening shear beneath the upper trough axis. Elsewhere, high pressure extending into the Gulf of Mexico will maintain offshore winds, with no thunderstorms forecast across the remainder of the CONUS. ..Jewell.. 12/28/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
