SPC Mar 3, 2022 2000 UTC Day 1 Convective Outlook

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0156 PM CST Thu Mar 03 2022 Valid 032000Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are expected across portions of southern California tonight. ...Discussion... Analysis of the latest model and observational data continues to suggest that mid-level destabilization across southern California, expected to occur overnight as a mid-level low approaches the region, will support low-topped showers and a few thunderstorms. Therefore, no changes appear to be needed with respect to the ongoing oulook. ..Goss.. 03/03/2022 .PREV DISCUSSION... /ISSUED 1015 AM CST Thu Mar 03 2022/ ...Southern CA... No changes have been made to the existing forecast. A compact upper low is approaching southern CA. This feature will be accompanied by a pocket of cold temperatures aloft, marginal instability, and enhanced large-scale lift. This should be sufficient for scattered showers and a few thunderstorms along/behind the front as it moves ashore after midnight. Gusty winds or small hail could accompany the strongest cells, but organized severe storms appear unlikely. ...Central CA... A burst of lightning activity has been recently noted along a line of convection extending roughly from San Jose to west of Sacramento. While there is some potential that further lightning flashes will occur in this region, weak and weakening instability fields suggest that the overall threat is expected to remain below 10% coverage.
