SPC 1930Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1233 PM CST Wed Jan 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast through Friday night. ...Central to eastern Gulf Coast... Thunder potential appears quite limited on Friday as poor to weak mid-level lapse rates persist downstream of a positive-tilt longwave trough. Buoyancy inland appears negligible, but meager MUCAPE over the north-central Gulf may be sufficient for a thin, low-topped convective line to shift east through the day from coastal southeast LA through the FL Panhandle.

Isolated, non-severe thunderstorms are possible across parts of the western Gulf Coast States on Thursday into Thursday night. ...TX/LA... A northern-stream shortwave impulse should phase with the closed mid/upper low in the Gulf of CA vicinity, yielding a longwave trough from south-central Canada to northwest Mexico by Thursday night. Downstream low-level warm-moist advection will yield increasingly widespread precipitation across the south-central states on Thursday as a weak surface

Very isolated thunderstorms are possible across parts of the Trans-Pecos to central Texas on Wednesday night. ...TX... An initially closed mid/upper low should gradually evolve back into an open, positive-tilt trough by early Thursday as it slowly slides across the southern Gulf of CA and northwest Mexico. Warm-moist advection at 700 mb should yield scant buoyancy with mixed-phase states in elevated parcels amid steep mid-level lapse rates. Most

Severe thunderstorms are not expected Tuesday or Tuesday night across the continental U.S. ...Discussion... In the wake of a strong cold front, over the western Atlantic and southern Gulf of Mexico Tuesday morning, cold/Arctic high pressure will continue expanding, to encompass much of the CONUS. In the Southwest, a mid-level short-wave trough -- on the western fringe of broad cyclonic flow covering most of the U.S. -- will

Local severe risk will be possible on Monday from northern Florida into southern and eastern Georgia. ...Synopsis... A weakening mid-level low, expected to reside near the Mid-Mississippi Valley early Monday, will shift quickly eastward, moving off the Mid-Atlantic Coast through latter stages of the period (Tuesday morning). Meanwhile at the surface, an associated cold front is forecast to sweep

A mid-level trough will amplify and become negatively tilted on Monday as it moves from the central Plains to the Northeast by 12Z Tuesday.

Severe thunderstorm potential is expected to remain limited on Sunday. ...Synopsis... A broad mid-level trough will move from the Great Basin on Sunday morning to the central Plains by Monday morning, amplifying early Monday morning. Lee troughing will persist through the period across the Plains which will strengthen the low-level jet and increase moisture advection into the Plains and Ozarks. Weak isentropic ascent could lead to isolated thunderstorm

A compact shortwave trough near the Four Corners Area should move across the southern Rockies into the central Great Plains. The attendant surface cyclone will be weak, tracking from the Raton Mesa vicinity to eastern KS. Modifying moisture return from the western Gulf will become sufficient for elevated convection by Friday Night across parts of the south-central states. Moderate
