THEREAFTER...WE SHOULD KEEP ENOUGH MOISTURE IN THE AREA FOR A CHANCE OF THUNDERSTORMS INTO NEXT WEEKEND. && .DISCUSSION...SCATTERER SHOWERS AND A FEW THUNDERSTORMS CONTINUED THIS MORNING ACROSS MAINLY COCHISE AND EASTERN SANTA CRUZ COUNTIES. SHOWERS WERE ALREADY STARTING TO DEVELOP FARTHER WEST OF THIS AREA...GENERALLY WEST TO SOUTHWEST OF TUCSON. SEVERAL INGREDIENTS WILL BE IN PLACE ACROSS SOUTHEAST ARIZONA TODAY THAT SUPPORT MORE ORGANIZED THUNDERSTORM ACTIVITY COMPARED TO YESTERDAY. THE CURRENT FORECAST WAS HANDLING THIS THINKING WELL...SO NO UPDATES NECESSARY THIS MORNING.

COMBINED WITH ELEVATED MOISTURE...(PRECIPITABLE WATER VALUES IN THE 1.45 TO 1.7 INCH RANGE)...THIS FEATURE AND THE ACCOMPANYING INCREASING EASTERLY FLOW WILL COMBINE TO ENHANCE OUR THUNDERSTORM COVERAGE TODAY AND TUESDAY. ORGANIZED OUTFLOWS WITH STRONG GUSTY WINDS A CONCERN ALONG WITH LOCALLY HEAVY RAINFALL ASSOCIATED WITH STRONGEST STORMS. WE WILL ALSO PROBABLY LOSE SOME OF OUR NORMAL DIURNAL TRENDS AS STORMS TEND TO BOTH LINGER OVERNIGHT AND INITIATE NEW ACTIVITY ALONG PREVIOUS OUTFLOWS AND RESIDUAL BOUNDARIES. WE SHOULD TREND DOWN BY WEDNESDAY OR THURSDAY COMPARED TO EARLIER IN THE WEEK AS WE SEE A DOWN DAY OR TWO AFTER ALL THE ACTIVITY AND WEAK SUBSIDENCE BEHIND THE FEATURE AS IT ROTATES NORTHWEST OF US. PREVIOUSLY WE WERE THINKING WE MIGHT DRY OUT A BIT AS WELL...BUT LATEST ECMWF TRENDS KEEP SOUTHEAST ARIZONA WITH A DECENT SUPPLY OF MOISTURE INTO NEXT WEEKEND. PERHAPS NOT QUITE TO CURRENT LEVELS WHICH ARE RUNNING AROUND 150 PERCENT OF CLIMO...BUT PROBABLY STILL ENOUGH TO DO THE JOB.
