At least some severe-weather potential is expected across East Texas and the Deep South for Friday/Day 4 and Saturday/Day 5. On Friday/Day 4, a secondary shortwave trough may evolve across the southern Plains in the wake of the shortwave trough related to Thursday's/Day 3 severe potential. While some severe storms could occur across east/southeast Texas toward the ArkLaTex on Friday/Day 4, details of available buoyancy are uncertain, especially given the short periodicity between these mid-level

Severe thunderstorms are not forecast through tonight across the contiguous United States. ...Synopsis... Water-vapor imagery this morning shows a mid-level trough over AZ moving east and a northern stream trough over the Pacific Northwest. The northern mid-level trough will latitudinally expand southward into the central Rockies/south-central High Plains as a ridge amplifies over the Interior West in its wake. As this occurs, a partial phasing of mid-level trough

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0355 AM CST Mon Dec 23 2024 Valid 261200Z - 311200Z ...DISCUSSION... Severe-weather potential is still expected for Days 4-6 Thursday-Saturday, as an upper trough emerging from California and the Southwest deserts moves toward the Ozarks/Deep South by Thursday/Day 4. At least a low-end multi-day regional severe risk is expected across south-central and east/southeast Texas towards parts of the ArkLaTex, and possibly the Lower Mississippi Valley. In particular, Thursday/Day 4 could ultimately warrant Slight Risk-caliber severe probabilities across south-central to east/southeast Texas although guidance variability persists, while
