AZZ020>028-CAZ030>033-201200- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1015 PM MST THU JUL 19 2007 UPDATED AVIATION SECTION SOUTH-CENTRAL AND SOUTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA FORECAST DISCUSSION .SYNOPSIS... STRONG HIGH PRESSURE ALOFT THAT HAS BEEN CENTERED OVER COLORADO IS MOVING NORTHEAST AWAY FROM ARIZONA. THIS MEANS LOWER TEMPERATURES FRIDAY AND SATURDAY...WITH NEAR-AVERAGE TEMPERATURES FOR LATE JULY CONTINUING THROUGH THE MIDDLE OF NEXT WEEK. A DEEPER FLOW OF MOISTURE FROM THE EAST AND SOUTHEAST WILL BRING A CHANCE OF DESERT DUST STORMS...AS WELL AS A CHANCE FOR SHOWERS AND THUNDERSTORMS... DURING THE NEXT FEW DAYS. A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE MIDDLE OF NEXT WEEK...WITH THE BEST CHANCE IN THE HIGHER TERRAIN EAST OF THE GREATER PHOENIX AREA DURING THE AFTERNOONS AND EVENINGS. && .SHORT TERM... TONIGHT THROUGH SATURDAY... IMPRESSIVE MCS DEVELOPED OVER SOUTHERN AZ THIS EVENING...WITH COLDEST CLOUD TOPS 50-55 KFT AND CLOUD TOP TEMPS -70C OR SO. COLD POOL EMANATING FROM THIS COMPLEX WAS MOVING NORTH ACROSS SOUTH-CENTRAL AZ DESERT...WITH LEADING EDGE PUSHING INTO THE FAR SOUTHEAST PORTION OF THE GREATER PHOENIX METROPOLITAN AREA AS OF 945 PM. DUST STORM WARNING WAS ISSUED FOR MUCH OF THE SOUTH-CENTRAL DESERT EARLIER THIS EVENING...AND SPOTTERS FROM ARIZONA CITY AND CHANDLER HEIGHTS HAVE ALREADY REPORTED VISIBILITY LESS THAN ONE QUARTER MILE. AWW WAS ISSUED FOR PHX SKY HARBOR...VALID BETWEEN 10 AND 11 PM...AS WIND COULD GUST TO 35KT THERE (HIGHER GUSTS HAVE ALREADY OCCURRED AT KIWA). ISOLATED STORMS HAVE BEEN TRIGGERED TO THE NORTH OF THE CORE OF THE MCS...MAINLY OVER NORTHERN PINAL COUNTY...AND STORMS WERE DEVELOPING ACROSS THE SOUTHEAST VALLEY AS WELL. EXPECT SCATTERED THUNDERSTORMS TO AFFECT METRO PHOENIX DURING THE NEXT COUPLE OF HOURS AS THE OUTFLOW BOUNDARY PUSHES NORTHWEST ACROSS THE ENTIRE METROPOLITAN AREA. 03Z PHOENIX SOUNDING SHOWED DRY ADIABATIC LAPSE RATE FROM SFC TO NEAR 550 MB...AND MIXING RATIO NEAR 10 G/KG IN SFC-850 MB LAYER...SO ELEVATED CAPE WAS DECENT...WITH BASE OF CAPE LAYER NEAR 13KFT MSL. SFC DEW POINTS HAD RISEN TO THE MID-UPPER 50S OVER SOUTH-CENTRAL AZ...WHICH FIT NICELY WITH OBSERVED LOW LEVEL MIXING RATIO. CURRENT TAF CALLS FOR TSTM BASES NEAR OR SLIGHTLY BELOW 13KFT MSL. WILL NEED TO WATCH FOR MICROBURST POTENTIAL WITH STORMS DURING NEXT COUPLE OF HOURS...AS WELL AS BRIEF HEAVY RAIN...IN ADDITION TO THE ONGOING DUST STORM. FROM PREVIOUS DISCUSSION... STRONG HIGH PRESSURE ALOFT THAT HAS BEEN CENTERED OVER COLORADO AND RESPONSIBLE FOR THE 110 DEGREE PLUS WEATHER OVER THE LOWER DESERT WILL MOVE NORTHEAST TO THE VICINITY OF NEBRASKA AND SOUTH DAKOTA BY THE WEEKEND...ALLOWING DAYTIME HIGHS AND NIGHTTIME LOWS TO MOVE CLOSER TO AVERAGE VALUES FOR MID-LATE JULY. AT THE SAME TIME...A DEEPER FLOW OF MOISTURE MOVING ACROSS OUR AREA FROM THE EAST AND SOUTHEAST WITH AN APPROACHING LOW PRESSURE SYSTEM WILL BRING A BETTER CHANCE OF DESERT DUST STORMS...SHOWERS AND THUNDERSTORMS TO SOUTH-CENTRAL ARIZONA TONIGHT...AS WELL AS FRIDAY AFTERNOON AND NIGHT. HAVE KEPT THE FORECAST BROAD-BRUSHED WITH A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE ENTIRE AREA THIS WEEKEND AS THE MOISTURE SPREADS WEST...EXCEPT FOR A CHANCE OVER THE HIGHER TERRAIN EAST OF THE GREATER PHOENIX AREA. && .LONG TERM... SUNDAY NIGHT THROUGH THURSDAY... PREVIOUS DISCUSSION... THE ATMOSPHERE WILL BE QUITE MOIST THROUGH THE ENTIRE LAYER...WITH LITTLE DAY TO DAY CHANGE EXPECTED. THUS...ITS DIFFICULT TO DETERMINE WHICH DAYS WILL SEE BETTER CONVECTION. IF WE END UP AS MOIST AS THE GFS IS SUGGESTING...WE COULD BE TOO MOIST FOR THUNDERSTORMS TO GET GOING HERE IN THE DESERT. WITH A SIGNIFICANT AMOUNT OF CLOUD COVER... ITS DIFFICULT TO GET SUFFICIENT SURFACE HEATING AND THUS A LIFT MECHANISM FOR THE MOISTURE (WITH THE EXCEPTION OF ANY DISTURBANCES THAT MAY MOVE THROUGH THE EASTERLIES). WE COULD END UP WITH PARTLY SUNNY/MOSTLY CLOUDY...MUGGY DAYS... WITH TEMPS ACROSS THE WARMEST DESERTS BELOW NORMAL FOR THIS TIME OF YEAR. THAT SAID...PLENTY OF UNCERTAINTY EXISTS FOR THE EXTENDED PORTION OF THE FORECAST... ESPECIALLY ACROSS THE DESERTS THIS TIME OF YEAR. && .AVIATION... JULY 20 0500 UTC GUSTY SOUTHEAST WINDS AND DENSE BLOWING DUST WILL AFFECT KIWA/KPHX THROUGH AT LEAST 06Z. THUNDERSTORMS WILL BE IN THE VICINITY OF BOTH SITES THROUGH AT LEAST 08Z...AND STRONG GUSTY WINDS AND BRIEF HEAVY RAIN WILL BE POSSIBLE. DEBRIS CLOUDS AND LIGHT RAIN SHOWERS WILL BE POSSIBLE UNTIL 10Z. ORGANIZED MCS OVER SOUTHERN AZ WILL LIKELY PROPAGATE A BIT FURTHER TOWARD THE WEST...BUT OUTFLOW WINDS WILL PROBABLY REMAIN EAST OF KYUX/KIPL/KBLH. WILL CONTINUE TO MONITOR... SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL FOR MORE DETAILED INFORMATION. AVIATION DISCUSSION IS NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... HIGH PRESSURE OVER THE ROCKIES AND GREAT PLAINS...TOGETHER WITH A DISTURBANCE IN NORTHERN MEXICO...WILL ALLOW FOR AN INCREASE IN MOISTURE THROUGHOUT THE REGION THIS WEEKEND. THE FAVORABLE FLOW PATTERN IN THE UPPER LEVELS WILL MEAN A BETTER CHANCE OF WETTING RAIN EACH DAY THIS WEEKEND...WITH THE HIGHEST PROBABILITIES IN ZONE 133. MINIMUM RH IS EXPECTED TO BE SOMEWHAT HIGHER EACH DAY...AND THE OVERNIGHT RECOVERIES ARE EXPECTED TO BE VERY GOOD. SOME LOCATIONS IN ZONE 133 MAY HAVE 90 TO 100 PERCENT RH DURING PRECIP EVENTS. THERE WILL ALSO BE SLIGHT CHANCES OF SHOWERS AND THUNDERSTORMS ACROSS THE SOUTH-CENTRAL DESERTS EACH DAY. ALSO...EXPECT SLIGHT CHANCES FOR STORMS OVER SERN CA AND THE WESTERN AZ DESERTS. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...NONE.
