   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe storms are not expected across the U.S. Friday.

   ...Synopsis...
   Though an upper low will move across southern Quebec and adjacent
   New England through the first half of the period, quasi-zonal flow
   is progged across the U.S. Friday -- particularly as eastern U.S.
   cyclonic flow associated with the low shifts into the western
   Atlantic with time.  Farther west, a weakening upper low off the
   Pacific Northwest Coast at the start of the period is forecast to
   shift across the northwestern states as an open wave, through
   Saturday morning.

   At the surface, high pressure will largely prevail over the U.S., as
   a surface low shifts away from northern New England into the
   Canadian Maritimes and the trailing cold front crosses the western
   Atlantic and Gulf of Mexico.

   Showers -- and possibly a thunderstorm or two -- may occur over
   parts of southern and eastern Florida, near and just north of the
   southward-moving surface front.  Showers, and again the chance for
   occasional clusters of lightning, are expected over parts of the
   Northwest as the upper system moves inland.  In both areas -- and
   elsewhere across the U.S. -- severe weather is not expected.
