Severe thunderstorms are not expected on Friday. ...Central to east TX... Pronounced forcing for ascent ahead of a slow-moving shortwave trough over the southern Great Plains will likely support a continued swath of elevated convection. This activity should be centered on north to west-central TX at 12Z Friday and gradually progress east-southeast into the Sabine Valley to Upper TX Gulf Coast by early Saturday. Elevated parcels should consist of minimal to meager buoyancy as mid-level lapse rates become largely moist-adiabatic in the southeast quadrant of the trough. Embedded thunderstorm coverage will probably remain isolated. Across south TX, confidence is below average in the southward extent of thunder potential. Guidance spread increases with the latitudinal placement of the shortwave trough as it begins to phase with a separate northern-stream shortwave trough amplifying from Alberta into the northern Great Plains. ..Grams.. 12/13/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
