A DISTURBANCE IN THE MOIST FLOW ALOFT WILL CONTINUE MOVING TO THE NORTHWEST TODAY. THIS SYSTEM WILL KEEP CLOUDS AND SHOWERS ACROSS MOST OF SOUTH-CENTRAL ARIZONA INTO TONIGHT.

ALSO...EXPECT LITTLE CHANGE IN TEMPERATURE. && .DISCUSSION... LAST NIGHTS CONVECTION WAS AGAIN LARGELY INDUCED BY UPPER LEVEL DYNAMICS. BEST LAYER TO LOOK AT WAS THE 500-400MB LAYER WHERE IT WAS ALREADY SATURATED FROM OLDER MESO-SCALE CONVECTION. WITHIN THIS LAYER WE SAW AN INVERTED TROUGH MOVING WEST TOWARD SE CALIFORNIA AND A DIFFLUENT PATTERN...WINDS DIVERGING ALONG AN AXIS ROUGHLY FROM PHOENIX TO LAKE HAVASU CITY TO LAS VEGAS. PHOENIX DEW POINT PROFILE WAS ALSO IMPRESSIVE WITH LOTS OF MOISTURE ALL THE WAY UP. IN FACT THE PRECIP WATER VALUE WAS UP TO 2.04 INCHES. WITH SOMEWHAT LOWER VALUES UPSTREAM...AND AN AREA OF LESS CLOUD COVER OVER SE ARIZONA INTO SOUTHWEST NEW MEXICO...WE WILL PROBABLY SEE AN UPSWING IN THE AFTERNOON CONVECTION ONCE AGAIN. MADE SOME MORNING UPDATES...TO INCLUDE HIGHER POPS FOR A LARGE AREA OF OUR CWA. TAFS ALSO NEEDED SOME AMENDING...SEE BELOW. WITH THE AXIS OF THE VORT LOBE DRIFTING TO THE NW...AND A RATHER UNI-DIRECTIONAL STEERING PATTERN TO THE SE...WE WILL KEEP POPS ABOUT WHERE THEY ARE FOR TONIGHT...AND INTO TUESDAY.
