...NO TSTM AREAS FORECAST...

...SUMMARY...
NO AREAS OF THUNDERSTORMS ARE EXPECTED ACROSS THE CONTINENTAL U.S.
TODAY.

...SYNOPSIS...
HIGH-AMPLITUDE UPPER-AIR PATTERN WILL PERSIST...FEATURING MEAN RIDGE
OVER WRN CONUS AND MEAN TROUGH INVOF E COAST.  FORMERLY CLOSED
LOW...NOW WEAKENING/OPEN-WAVE TROUGH...IS MOVING NNEWD OVER SRN CA
ATTM.  SHORTWAVE DEAMPLIFICATION WILL CONTINUE AS THAT FEATURE TURNS
NEWD OVER GREAT BASIN TODAY...THEN EWD OVER CENTRAL ROCKIES AND
THROUGH LARGE-SCALE RIDGE TONIGHT.  WHILE A ROGUE LIGHTNING STRIKE
CANNOT BE RULED OUT FROM ASSOCIATED MIDLEVEL CONVECTION OVER
NV/UT...BUOYANCY AND MOISTURE SHOULD REMAIN TOO SCANT FOR GEN TSTM
THREAT.

OTHERWISE...STG DEEP-LAYER CYCLONE NOW CENTERED OFF SRN NEW ENGLAND
IS EXPECTED TO MOVE NEWD TOWARD BAY OF FUNDY REGION THROUGH PERIOD.
LARGE/LOW-THETAE ANTICYCLONE IN LOW LEVELS WILL FOLLOW THAT SYSTEM
ACROSS ERN CONUS...WITH RIDGING EXTENDING SWWD ACROSS GULF OF
MEXICO.  THIS WILL PRECLUDE ENOUGH MOISTURE FOR TSTMS E OF ROCKIES.
