SPC Mar 14, 2023 0600 UTC Day 1 Convective Outlook

LIVE MAP (ABOVE) ... SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1228 AM CDT Tue Mar 14 2023 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast Tuesday. ...Discussion... Eastern US trough is forecast to move off the Atlantic Coast during the latter half of the period as the associated upper low deepens just east off the MA Coast. As a result, strong surface anticyclone will settle into the MS/OH Valley region and this feature will dominate much of the country east of the Rockies. Offshore flow will prove detrimental for meaningful instability and the prospect for severe thunderstorms is very low. Weak convection may develop ahead of the front over extreme south FL, portions of TX ahead of a weak short-wave trough, and across portions of CA in response to the next in a series of short waves. In each area, limited buoyancy will result in just isolated thunderstorms where convection is able to deepen enough for lightning discharge. ..Darrow/Bentley.. 03/14/2023 Read more CHECK UPDATE ZOOM GRAPHIC
