...NO TSTM AREAS FORECAST...

...SYNOPSIS...
LOW AMPLITUDE CYCLONIC FLOW WILL PREVAIL ACROSS MOST OF THE U.S.
THIS PERIOD...AS THE SRN EXTENT OF ERN CANADA TROUGHING IS
SUPPRESSED A BIT AS A SHORT-WAVE TROUGH VACATES THE E COAST. WITH
TIME HOWEVER...A SECOND SHORT-WAVE TROUGH -- DIGGING SEWD ACROSS THE
CANADIAN ROCKIES AND PRAIRIE PROVINCES TOWARD THE N CENTRAL U.S. --
RESULTS IN RE-AMPLIFICATION OF THE LONG WAVE PATTERN.

AT THE SURFACE...A CLIPPER-TYPE LOW PRESSURE SYSTEM IS FORECAST TO
ACCOMPANY THE DIGGING CANADIAN TROUGH...WHILE HIGH PRESSURE BUILDS
ACROSS THE SRN AND ERN STATES IN THE WAKE OF THE PRIOR COLD FRONT.
GIVEN THE COOL/CONTINENTAL AIR...THUNDERSTORMS ARE NOT EXPECTED.
