   Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0744 PM CDT Mon Oct 18 2021

   Valid 190100Z - 191200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk for severe thunderstorms appears negligible across the U.S.
   tonight.

   ...01Z Outlook Update...
   Forcing for ascent and mid-level cooling, associated with a closed
   low migrating across the eastern Great Basin into the Wyoming and
   Colorado Rockies tonight, may continue to support destabilization
   marginally supportive of convection briefly capable of producing
   lightning.  Isolated, brief weak thunderstorm development might also
   still be possible this evening across the mountains of southwest
   Texas, beneath difluent, cyclonic mid/upper flow.  Otherwise, dry
   and/or stable conditions will generally prevail across much of the
   rest of the U.S., with negligible risk for thunderstorms.
