SATELLITE ANALYSIS AND TRENDS...OVERALL PICTURE AS SEEN BY THE CIRA
EXPERIMENTAL LAYERED PW PRODUCT SHOWS DEEP LAYERED MOISTURE NUDGING
INTO S AZ WITH A CONNECTION TO TROPICAL STORM KEVIN IN THE E PAC.
LATEST WATER VAPOR IMAGERY DEPICTS SHORTWAVE TROUGH MOVING THROUGH W
MEXICO AND SW AZ AIDING IN ASCENT AS HEIGHT FALLS OVERSPREAD THE AREA
HELPING TO SUPPORT CONVECTION IN SONARA MEXICO AND S-CENT AZ. RAPID CU
GROWTH WAS SEEN IN RECENT VISIBLE IMAGERY AS CONVECTION IS FED BY DEEP
LAYERED MOISTURE AND UPSTREAM INSTABILITY DETECTED BY GOES SOUNDER.
GPS NETWORK IN S-CENT INDICATES A PW VALUES OF 1.6" WHICH IS AROUND 1.5
STANDARD DEVIATIONS ABOVE NORMAL. SOUTHERLY MOISTURE ADVECTION INTO
AN AREA OF BROAD UPPER LVL DIFFLUENCE OVER S AZ AND W MEXICO SHOULD
PROMOTE BACKBUILDING INCREASING THE HEAVY RAIN THREAT FOR THE AREA.
CONVECTION THAT FORMED IN E SONARA COULD TEMPORARY INHIBIT CONVECTIVE
GROWTH IN SE AZ AS INFLOW FROM THE CLOUD BEARING LAYER WAS ABSORBED BY
THIS AREA OF CONVECTION NOW TRAVELING S. A MITIGATING FACTOR FOR S-CENT
AZ IS CONVECTION IN N-CENT SONARA MAY IMPEDE INFLOW OF INSTABILITY
AND MOISTURE TO CURRENT CONVECTION THUS MAKING THIS SITUATION MORE OF
A LOCALIZED HEAVY RAIN THREAT.  ALTHOUGH CONVECTION IN SONARA SHOULD
EVENTUALLY TRACK INTO AZ AS IT BECOMES COOL POOL DOMINATED PROMOTING SOME
TEMPORARY TRAINING. FOR MORE INFORMATION ON THIS EVENT PLEASE SEE WPC ERD.
