   ...NO THUNDERSTORM AREAS FORECAST...

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

   ...Discussion...
   Models indicate that mid-level ridging across the far western
   Canadian Provinces will become suppressed by another short wave
   perturbation emerging from the upstream mid-latitude Pacific, but
   not before downstream troughing continues to dig southeast and south
   of the northern U.S. Rockies.  This will reinforce larger scale
   troughing across much of the interior into eastern United States. 
   Although surface ridging initially across much of the Gulf Coast and
   Atlantic Seaboard is forecast to weaken, seasonably cold and stable
   boundary-layer conditions may be slow to moderate.  It appears that
   another expansive surface ridge will build across the Great
   Basin/Rockies into the Great Plains, with a reinforcing intrusion of
   arctic air surging through much of the upper Mississippi Valley and
   northeastern Great Plains, today through 12Z Thursday.
