12PM Day 3 Convective Outlook for Monday, December 1. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
Scattered thunderstorms may develop along the Gulf Coast Monday into early Tuesday morning. Severe thunderstorms are not currently expected.
Gulf Coast/Southeast
An upper trough oriented from the northern Plains to southern Rockies will develop eastward to the Great Lakes and Lower MS Valley on Monday. Strengthening midlevel southwesterly flow ahead of this feature will overspread the Southeast. A prior cold frontal passage into the Gulf on Day 2/Sunday and surface high pressure persisting across the Midwest and eastern states will limit northward transport of richer Gulf moisture, keeping any quality moisture very near the coast. Nevertheless, increasing midlevel moisture and steepening lapse rates aloft, and another approaching cold front could support isolated thunderstorms across the Gulf Coast/Southeast vicinity once again on Monday. Severe storms are not expected as destabilization will remain meager.
