   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1254 AM CST Mon Jan 20 2025

   Valid 221200Z - 231200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not forecast on Wednesday.

   ...Synopsis...
   An elongated upper trough will exit the East Coast early in the day,
   as another positive-tilt trough moves into the central CONUS. This
   trough will extend roughly from the upper Great Lakes into the
   southern Plains. Meanwhile, an upper ridge will exist along the West
   Coast, with additional disturbances diving south into the northern
   Rockies.

   At the surface, a stable air mass in terms of convection will exist
   due to high pressure. A weak surface low may form from the FL
   Straits toward the Bahamas, avoiding the FL Peninsula where the air
   mass will remain stable. As such, little to no lightning activity is
   forecast across the USA on Wednesday due to the stable air mass over
   land.
