   ...NO SEVERE THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   Thunderstorms will continue across portions of the Intermountain   
   West and Texas/Louisiana coasts through this evening. The overall   
   threat for organized severe thunderstorms appears low.   
      
   ...20z Update...   
   The Marginal Risk across southern Idaho/northern Utah has been   
   removed with this outlook. Thunderstorm activity has shown gradual   
   weakening with only meager MLCAPE remaining. Occasional strong   
   gradient winds will continue with the upper-level wave but the   
   overall convective severe threat appears to be waning.

   .PREV DISCUSSION... /ISSUED 1022 AM CST Wed Dec 17 2025/   
      
   ...Interior Northwest and Northern Great Basin/Rockies...   
   A powerful mid-level shortwave trough and associated sub-980 mb   
   surface low will move quickly eastward today across the interior   
   Northwest/northern Rockies and adjacent western Canada. A strong   
   surface cold front will likewise translate east-southeastward over   
   the northern Intermountain/Great Basin region late this morning into   
   the afternoon. Widespread cloud cover remains prevalent ahead of the   
   front across southern ID into northern UT and vicinity, with cool   
   surface temperatures and very limited low-level moisture also   
   present. MUCAPE is expected to remain only barely sufficient to   
   support convection. But, given the enhanced flow at low levels noted   
   on recent VWPs from KCBX/KSFX, it is not entirely out of the   
   question that convectively augmented gusts may exceed the already   
   strong background gradient winds on a localized basis. The Marginal   
   Risk has therefore been maintained for parts of southern ID/northern   
   UT and vicinity, even though the overall threat for organized severe   
   thunderstorms will remain low.
