.DISCUSSION...
AN UPPER TROUGH WAS MOVING ACROSS COLORADO THIS MORNING...TRAILING
BACK INTO NORTHERN AZ...WHILE AN UPPER CLOSED LOW CONTINUED TO SIT
OVER NORTHERN SONORA MEXICO.  UPPER LEVEL MOISTURE...WHILE STILL
CONCENTRATED EAST OF THE RIO GRANDE...HAS MANAGED TO GET PULLED BACK
INTO SE AZ BY THE UPPER LOW.  THIS ADDITIONAL MOISTURE AND THE
TRAILING TROUGH AXIS ALOFT WILL RESULT IN A SLIGHTLY BETTER CHANCE AT A
AFTERNOON THUNDERSTORMS ACROSS THE GILA REGION. STILL...THIS IS HARDLY
A SLAM-DUNK...AND STORMS ARE LIKELY TO BE ISOLATED AND TERRAIN-DRIVEN.
THE UPPER LOW WILL GET KICKED OUT OF THE AREA ON SATURDAY...AND AN
ISOLATED STORM WILL STILL BE POSSIBLE OVERNIGHT INTO SATURDAY MORNING.
DRIER AIR ALOFT WILL MOVE IN BEHIND THE SYSTEM FOR SATURDAY...BUT
LOW-LEVEL SOUTHEAST FLOW WILL KEEP SURFACE MINIMUM RH VALUES ABOVE 15%
THROUGH THE NEXT SEVERAL DAYS.  ANOTHER SHOT OF UPPER LEVEL MOISTURE
MAY COME INTO PLAY SUNDAY AS A TROPICAL DEPRESSION SOUTHEAST OF BAJA
GETS PULLED UP INTO THE REGION ALONG THE WEST EDGE OF THE SUBTROPICAL
HIGH.
