Severe thunderstorms are not expected on Wednesday. ...Central/Eastern Gulf Coast States... A southern-stream shortwave trough should gradually dampen as it progresses from the northwest Gulf Coast to off the South Atlantic Coast by 12Z Thursday. Guidance is rather consistent that rich low-level moisture will remain confined offshore across the northern Gulf, suggesting prospects will be slim for SBCAPE over land. Weak elevated buoyancy may support sporadic thunderstorms shifting from west to east through the period. The greatest thunder probabilities are across southeast LA early, with low chances farther east as the bulk of deep convection is expected to remain across the north-central to northeast Gulf. ...Coastal CA and AZ/NM... The southern one of the pair of shortwave impulses over the West Coast States should dig slightly as it progresses across the Lower CO Valley into AZ by early Thursday. Relatively cold mid-level temperatures from -25 to -30 C near 500 mb will expand/shift south and overlap scant surface-based buoyancy amid west-northwesterly low-level flow along the CA coast. This may yield very isolated thunderstorm coverage shifting from north to south, mainly during the first half of the period. The modest amplification of the shortwave trough on Wednesday night should strengthen large-scale ascent for low-topped convection across a portion of AZ to west NM. Scant buoyancy may support sporadic lightning flashes. ..Grams.. 01/02/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
