SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0204 AM CST Wed Nov 24 2021 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... No thunderstorms are forecast to develop across the contiguous United States on Friday. ...Synopsis... Upper troughing is forecast to cover the eastern CONUS early Friday morning, while an upper low remains centered over the Baja Peninsula and a belt a strong westerlies stretches from the northeast Pacific Ocean into the northern High Plains. The eastern CONUS upper trough is expected to remain progressive, quickly moving off the Eastern Seaboard while becoming more negatively tilted with time. A shortwave trough will move quickly through the westerlies, moving across the Pacific Northwest and northern Rockies and reaching the northern High Plains by early Saturday morning. At the same time, the upper low over Baja is expected to slowly drift eastward into northwest Mexico. At the surface, a cold front will likely stretch from southern New England southwestward through the eastern Carolinas and off the coast of the central FL Peninsula early Friday. This front will move eastward/southeastward throughout the day, but limited low-level moisture and buoyancy preceding the front will preclude thunderstorm development. Stable conditions are also expected elsewhere across the CONUS. ..Mosier.. 11/24/2021 Read more LIVE: spc.noaa.gov
