   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF   
   SOUTHERN IDAHO AND NORTHERN UTAH...   
      
   ...SUMMARY...   
   While strong to locally severe winds may occur with low-topped   
   convection through early afternoon across parts of southern Idaho   
   and northern Utah, the overall threat for organized severe   
   thunderstorms appears low.   
      
   ...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.
