   Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0742 PM CDT Tue Oct 27 2020

   Valid 280100Z - 281200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected across the contiguous United
   States through tonight.

   ...01z Update...

   Another spoke of large-scale forcing for ascent is spreading east
   into the TX south Plains this evening. Lightning has increased in
   coverage with weak convection along the leading edge of this forcing
   near the NM/TX border. 00z sounding from MAF exhibits roughly 200
   J/kg MUCAPE if lifting a parcel between 700-750mb. This band of
   convection should spread northeast into western OK tonight where the
   boundary-layer temperatures remain below freezing. Significant icing
   appears to be the primary threat with this activity.

   Scattered thunderstorms that developed across the central/eastern
   Gulf Coast region are slowly weakening as they advance inland. Some
   threat remains across this region tonight due to gradually
   increasing moisture/weak buoyancy ahead of TC Zeta.
