SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0128 PM CST Sun Jan 05 2025 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... 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 gradually cut off from the main belt of flow and shift southward across the Lower Colorado River Valley toward/into northwestern Mexico. Beneath the cold pool associated with the evolving low, steep mid-level lapse rates will contribute to meager CAPE, and possibly a couple of lightning strikes with scattered convection evolving overnight across central and southern Arizona. Elsewhere, thunderstorms are not expected through the period. ..Goss.. 01/05/2025
