WITH ABOVE NORMAL TEMPERATURES INTO THIS WEEKEND. A COUPLE OF VERY 
WEAK WEATHER DISTURBANCES PASSING BY THE FOUR CORNERS REGION LATE

.DISCUSSION...
A VERY TRANQUIL WEATHER DAY ACROSS THE PHX CWA. UNDER A STRONG HIGH 
PRESSURE SYSTEM ALOFT...SKIES WERE CLEAR WITH ONLY LIGHT WINDS. AFTN 
TEMPS WERE A HANDFUL OF DEGREES WARMER THAN THE SAME TIME YESTERDAY.

LATEST WV LOOPS SHOW A VIGOROUS UPPER TROUGH CRASHING INTO THE PACNW 
THIS AFTERNOON. THIS SHORTWAVE WILL WEAKEN SOME AS IT TOPS THE WRN 
RIDGE AND THEN WILL COME BARRELING SEWD INTO THE SRN ROCKIES BY LATE 
TUE/EARLY WED TIME FRAME. AS THE SYSTEM GRAZES BY TO OUR E...IT 
COULD GIVE SOME MINOR DAYTIME COOLING...BUT NOT MUCH. THE SYSTEM 
WILL BE DRY BY THE TIME IT GETS HERE...BUT EVEN SO...DECIDED TO 
LEAVE SOME SINGLE DIGIT POPS IN PLACE OVER THE FAR ERN CWA TUESDAY 
EVENING. 

BY THE END OF THE WEEK...A VERY SIMILAR LOOKING SHORTWAVE WITH A 
VERY DRY TRAJECTORY WILL PASS BY TO OUR E WITH THE SAME TYPES OF 
EFFECTS. AGAIN...LEFT SINGLE DIGIT POPS IN PLACE IN THE EXTENDED...
