SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0216 AM CST Sun Dec 05 2021 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States on Tuesday. ...Synopsis and Discussion... Large-scale upper troughing should once again develop across much of the central/eastern CONUS on Tuesday as a lead wave ejects from New England northeastward over the Canadian Maritimes. Surface high pressure is expected to dominate much of the CONUS east of the Rockies as it slowly shifts eastward to the Atlantic Coast through the period. Due to a prior frontal passage, rich low-level moisture is forecast to remain confined to parts of the immediate Gulf Coast. Only very weak boundary-layer instability is forecast to develop across parts of north FL Tuesday afternoon, and the potential for robust thunderstorms appears low. However, some elevated convection may occur mainly Tuesday evening/night from coastal TX to the central Gulf Coast states as modest low-level warm/moist advection develops on the southern periphery of the amplifying upper trough. ..Gleason.. 12/05/2021 Read more LIVE: spc.noaa.gov
