.DISCUSSION...EAST-WEST ORIENTED GRADIENT HAS BEEN SUFFICIENT FOR
BREEZY EASTERLY CANYON WINDS THIS MORNING WITH SPEEDS UP TO 25 MPH
TO CREST LEVEL. THIS SAID...HIGH PRESSURE ALOFT HAS BEEN ALLOWING
FOR STRONG OVERNIGHT INVERSIONS AND GENERALLY STABLE LOW LEVEL
CONDITIONS. DUE TO THIS VENTILATION WILL REMAIN QUITE LIMITED ALOFT
TODAY OWING TO CLEARING INDICES WELL BELOW 500. A WEAK TROUGH WILL
MOVE INTO THE REGION OVERNIGHT TONIGHT INCREASING CLOUD COVER...BUT
BOTH DECREASING LOW LEVEL WIND TRENDS AND LACK OF INSTABILITY ALOFT
WILL PIN CLEARING INDICES WELL BELOW 500 AGAIN FOR WEDNESDAY.

HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE IN THE BIG
PICTURE THROUGH THIS WEEKEND. THE NEXT BEST BET FOR IMPROVED CLEARING
WILL OCCUR EARLY NEXT WEEK AS HIGH PRESSURE SHIFTS EAST.
