12AM Day 2 Convective Outlook for Friday, January 30. NO THUNDERSTORM AREAS FORECAST
SUMMARY
Thunderstorms appear unlikely Friday through Friday night.
Synopsis
Large-scale ridging will generally be maintained across the western US as a broad, multi-component upper trough over the eastern half of the US is forecast to rapidly consolidate and strengthen Friday into early Saturday. A prominent shortwave impulse emanating from southern Canada will merge with several smaller perturbations over the southern MS Valley and Gulf Coast vicinity. The net result will be a large and intense positive tilt upper trough over the southeastern CONUS. This strong trough and 100+ kt mid-level flow will aide the development of an initially weak surface cyclone over the eastern Gulf and FL Peninsula. The low will rapidly deepen late Friday into early Saturday off the Atlantic coast as a cold front moves offshore. Ahead of the front, modest low-level moistening/destabilization is possible over parts of southern FL and the keys. However, this appears short lived and without more substantial ascent/destabilization, thunderstorms are unlikely.
