...NO TSTM AREAS FORECAST...

...SYNOPSIS...
SOME EWD PROGRESSION OF THE DEEP ERN STATES MID LEVEL TROUGH AND THE
RIDGE OVER THE ROCKIES IS EXPECTED THROUGH TOMORROW AS THE FIRST IN
A SERIES OF SHORTWAVE TROUGHS APPROACHES THE CA COAST. 
THUNDERSTORMS ARE NOT EXPECTED ACROSS THE MAJORITY OF THE CONUS AS A
RESULT OF STRONG SURFACE RIDGING AND OFFSHORE FLOW ACROSS THE GULF
AND ATLANTIC COASTS.  

THE TROUGH NEAR 130 W WILL REACH CA THIS EVENING...THOUGH THE WAVE
SHOULD LOSE SOME AMPLITUDE IS IT ENCROACHES ON THE BROAD RIDGE OVER
THE INTERMOUNTAIN WEST.  A COUPLE OF LIGHTNING STRIKES HAVE BEEN
NOTED IN OCEANIC LIGHTNING DATA...BUT WEAKENING OF THIS SYSTEM WITH
TIME SUGGESTS THAT ANY THUNDERSTORM THREAT SHOULD DIMINISH BEFORE
REACHING THE CA COAST. OTHERWISE...ANY WEAK MID LEVEL INSTABILITY
ASSOCIATED WITH THE LOW OVER NW MEXICO SHOULD REMAIN S OF THE RIO
GRANDE.
