.DISCUSSION...
TO THE WEST EARLY THIS MORNING...THE CLDS AND PCPN WEST OF IMPERIAL 
ARE REMAINING WEST OF THE COASTAL MTNS. THE WINDS ARE CRANKING UP 
WEST TO EAST ACROSS XTRM SE CA...SW AND S CENTRAL AZ.  THE MORNING 
YUMA SOUNDING INDCS THAT WINDS SHOULD REMAIN BELOW ADVSRY LEVEL FOR 
THE NEXT COUPLE OF HOURS AT BEST...HOWEVER THE DYNAMICS REQUIRE THAT 
THIS WILL NEED TO BE MONITORED CLOSELY TODAY.  BLOWING SAND AND DUST 
ADVISORIES...AS WELL AS WIND ADVISORIES MAY BE NEEDED THROUGH THE 
AFTERNOON HOURS. 

THE PRESENT COOLER TEMPERATURE FORECAST STILL LOOKS GOOD...AS MOST 
AREAS ARE 6 TO 10 DEGREES COOLER AT 10 AM MST TODAY COMPARED TO SAME 
TIME YESTERDAY.  PRECIPITABLE WATER IS ABOUT HALF OF WHAT IT WAS 
YESTERDAY...WE ARE DRYING OUT. THE BEST DYNAMICS OF THE S CA STORM 
SYSTEM WILL MOVE ACROSS OUR AREA LATE THIS AFTERNOON...IF WE SEE 
CONVECTION IT WILL BE AT THAT TIME.  ZONE FORECAST DAY TWO AND 
BEYOND STILL LOOKS GOOD...SO NO CHANGE.  RUNYAN
