...SYNOPSIS...
THE DEEP MID LEVEL LOW JUST OFF THE SRN CA COAST WILL BECOME AN OPEN
WAVE /WITH SEVERAL EMBEDDED SPEED MAXIMA/ AND EJECT ENEWD ACROSS THE
ROCKIES/PLAINS IN RESPONSE TO ANOTHER SHORTWAVE TROUGH MOVING SEWD
FROM THE GULF OF ALASKA.  STEEP LAPSE RATES/WEAK INSTABILITY WILL
ACCOMPANY THE EJECTING CA TROUGH ACROSS THE SW EARLY IN THE
PERIOD...WHERE ISOLATED THUNDERSTORMS WILL BE POSSIBLE.  THE THREAT
FOR THUNDERSTORMS SHOULD GRADUALLY DIMINISH LATER TOMORROW ACROSS
THE ROCKIES AS THE MID LEVEL TROUGH MOVES INLAND AWAY FROM THE
MOISTURE SOURCE AND LOSES AMPLITUDE...THOUGH VERY ISOLATED LIGHTNING
STRIKES STILL MAY OCCUR.  LATE IN THE PERIOD...A FEW THUNDERSTORMS
WILL BE POSSIBLE ACROSS COASTAL AREAS OF NRN CA/ORE AS THE GULF OF
ALASKA TROUGH MOVES INLAND.  

ELSEWHERE...LOW-LEVEL MOISTURE WILL CONTINUE TO SPREAD NEWD FROM THE
SRN PLAINS TO THE MID MS VALLEY IN CONJUNCTION WITH LEE CYCLOGENESIS
ACROSS THE CENTRAL AND NRN PLAINS.  ELEVATED INSTABILITY MAY BECOME
SUFFICIENT FOR ISOLATED THUNDERSTORMS IN A STRONG WAA PATTERN LATE
IN THE PERIOD ACROSS THE MID MS VALLEY.
