The risk for severe thunderstorms remains negligible across the U.S. tonight. ...01z Update... Plains upper trough will shift slowly east overnight with the primary zone of high-level diffluence expected to focus across the lower MS Valley and lower latitudes. Large-scale forcing should encourage surface cyclogenesis well offshore -- likely over the southern Gulf basin. Resultant low-level convergence over southeast TX/LA will be somewhat negated by this offshore development. Early-evening radar data suggests a few stronger showers are noted along the advancing cold front west of Victoria TX, but otherwise most convection remains quite shallow and lightning-free. While buoyancy will remain weak through sunrise, forecast soundings suggest some threat for lightning despite poor lapse rates/buoyancy. Lightning may also accompany deeper updrafts across extreme south FL, but more likely over the Straits. ..Darrow.. 12/16/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
