Day 1 Convective Outlook

1153 PM CDT Sun Oct 04 2020

Valid 051200Z - 061200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through Tuesday morning.

...Synopsis...
Broad cyclonic flow aloft will prevail across the central and
eastern CONUS through the day, with a mid-level trough ejecting into
the Atlantic at the start of the period, and a second trough
amplifying across the Mississippi Valley later in the day. Upper
ridging will also persist across the western U.S. While marginal
buoyancy (and an associated risk for a few thunderstorms) may
accompany the departing trough along the lower New England Coast,
mass subsidence across the western CONUS, and cool/stable low-level
conditions farther east are expected to limit convective potential
across most of the CONUS. The main exception will be the Florida
Peninsula, where some buoyancy accompanying low-level moist
advection may promote a few thunderstorms through the period.
