   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms will not occur on Sunday throughout the
   contiguous United States.

   ...Synopsis...
   A mid-level trough will amplify/expand across the Midwest and
   maintain cyclonic flow from the Prairie Provinces through the
   Midwest and into the lower Great Lakes.  At the surface, high
   pressure will extend from the northern High Plains through much of
   the area east of the Rockies.  Mid-level moisture and a series of
   very weak disturbances within a moderate belt of westerly flow will
   move across northern UT and CO.  Weak convection may yield a few
   lightning flashes with this activity.  Elsewhere, tranquil
   conditions will prevail.
