   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk of thunderstorms appears negligible across the U.S. Monday
   through Monday night.

   ...Synopsis...

   A series of weak mid/upper shortwave troughs will migrate through
   northwesterly large-scale flow from the Pacific Northwest to the
   northern/central Plains and Upper Midwest. A large-scale upper
   trough near the Atlantic coast will pivot east/northeast across New
   England and offshore the Mid-Atlantic coast. A surface cold front
   extending southward from the Canadian Prairies into the mid-MO
   Valley will shift across the mid/upper MS Valley to the lower Great
   Lakes/OH Valley by Tuesday morning. Persistent surface high pressure
   across the south-central and southeastern U.S. will result in
   continued offshore flow across the Gulf, resulting in a dearth of
   boundary-layer moisture east of the Rockies. As a result, stable
   conditions will preclude thunderstorm activity.
