1215 PM CDT Mon Oct 30 2023

Valid 311200Z - 011200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Tuesday.

....Synopsis...
In the wake of a strong cold front, an expansive surface ridge will
dominate the weather over most of the CONUS on Tuesday. Generally
dry and stable conditions will limit thunderstorm potential for most
areas. One possible exception is over the Great Lakes region, where
a mid/upper-level cyclone will gradually weaken and evolve into a
positively tilted shortwave trough Tuesday into Tuesday night.
Shallow convection that develops in response to cold midlevel
temperatures (around -20C at 700 mb) may be capable of producing
sporadic lightning flashes over the lakes and immediate downwind
lakeshore areas, with the greatest relative potential expected in
the Lake Michigan vicinity closer to the track of the midlevel cold
core and vorticity maximum.
