AZZ020>028-CAZ030>033-160000- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1015 AM MST SAT SEP 15 2007 .SYNOPSIS... A PACIFIC LOW PRESSURE SYSTEM WILL SLOWLY MOVE INTO THE WESTERN STATES...INCLUDING ARIZONA...THIS WEEKEND AND ON MONDAY. INCREASING MOISTURE FROM MEXICO WILL SPREAD INTO ARIZONA TODAY...WITH ADDITIONAL MOISTURE SUNDAY AND SUNDAY NIGHT. AS A RESULT...A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS SOUTHWEST AND SOUTH CENTRAL ARIZONA THIS AFTERNOON AND EVENING...WITH A BETTER CHANCE SUNDAY AFTERNOON THROUGH EARLY MONDAY ALONG A WEAK COLD FRONT. DRIER WEATHER WILL RETURN NEXT WEDNESDAY THROUGH FRIDAY... ALONG WITH NEAR NORMAL TEMPERATURES. && .SHORT TERM... TODAY THROUGH MONDAY... VIS SATELLITE IMAGERY TODAY COMPARED WITH YESTERDAY AT THIS TIME NOT ALL THAT DIFFERENT...EXCEPT FOR A FEW MORE CLOUDS OVER OUR FAR ERN CWA THIS MORNING. THIS CLOUDINESS IS INDICATIVE OF A MID-LEVEL MOISTURE INCREASE THAT OCCURRED OVERNIGHT FROM CONVECTION S OF THE BORDER. LATEST K1Y7 SOUNDING THIS MORNING IS NOW UP TO 1.33 INCHES PWATER...WITH SURFACE DEWPOINTS ACROSS THE CWA NOW WELL INTO THE 50S...EXCEPT 60S AND LOWER 70S OUT W. MEANWHILE...TAKING A LOOK AT THE WATER VAPOR IMAGERY...WE CAN CLEARLY SEE A SHORTWAVE TROUGH DOWN IN THE SCNTRL GULF OF CA. 12Z MODELS MOVE THIS FEATURE N/NEWD WITH TIME...WITH THE GFS HINTING AT THE POTENTIAL FOR A LARGE CONVECTIVE COMPLEX DEVELOPING SOMEWHERE OVER FAR SRN AZ LATE TODAY. IF THIS OCCURS...WE WOULD NEED TO BE ON THE WATCH FOR SOME OUTFLOW BOUNDARIES AND POTENTIAL DUST STORMS IN OUR ERN LOWER DESERTS THIS EVENING. ALSO...WITH THE AMS JUICING UP NICELY...WE SHOULD SEE A PRETTY DRAMATIC INCREASE IN TSTMS ACROSS MAINLY THE AZ PORTION OF THE CWA BY SUNDAY AFTN/EVE...CONTINUING PERHAPS INTO MONDAY. MAYBE EVEN SOME SEVERE WX WITH THIS TRANSITION EVENT/COOL FRONTAL PASSAGE. TO BE SURE...IT APPEARS WE ARE HEADED INTO A FAIRLY ACTIVE COUPLE OF DAYS. CURRENT FORECASTS APPEAR TO HAVE THE SITUATION WELL IN HAND... SO NO UPDATES NEEDED THIS MORNING. && .LONG TERM... MONDAY NIGHT THROUGH FRIDAY... ASIDE FROM A FEW LINGERING SHOWERS/TSTMS OVER ZONE 24 MONDAY EVENING...WE SHOULD BE IN FOR A NICE...DRY AND SEASONABLY MILD WEEK WX-WISE. NOT READY TO BUY INTO NEXT TROUGH BEING FORECAST BY LAST COUPLE OF GFS RUNS. JUST SEEMS LIKE IT IS TOO EARLY IN THE SEASON TO HAVE THIS STRONG OF A TROUGH DROP DOWN THIS FAR S. PREFER THE EURO/ UKMET SOLUTIONS OF A MUCH FARTHER N TROUGH LATER THIS WEEK. WILL THEREFORE KEEP EXTENDED DRY...WITH NEAR NORMAL TEMPS. && .AVIATION... SEPTEMBER 15 1710 UTC (SEPTEMBER 15 1010 MST) WINDS ALONG THE LOWER COLORADO RIVER VALLEY HAVE INCREASED DURING THE LAST SEVERAL HOURS WITH CONSIDERABLE LOW-LEVEL MOISTURE ADVECTION.

SOUNDINGS FROM 1Y7 THIS MORNING HAVE SHOWN PRECIP WATER INCREASED TO 1.33 INCHES AND MODELS HAVING A HARD TIME KEEPING UP WITH THIS RAPID INCREASE. TAFS WILL SHOW A BIT OF AN INCREASE IN CU/TCU AND SOMEWHAT LOWER CLOUD BASES. NOT VERY CONFIDENT WITH MENTIONING TSRA AT ANY OF THE TERMINALS AT THIS TIME...BUT WE COULD SEE SOME OUTFLOW BOUNDARIES MOVE INTO THE PHOENIX AREA AFTER 01Z. LOOK FOR BETTER TSTM CHANCES SUNDAY INTO MONDAY. SEE TAFS PHXTAFPHX...PHXTAFIWA...PHXTAFYUM...LAXTAFBLH AND LAXTAFIPL FOR MORE DETAILED INFORMATION.

THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE SUNDAY NIGHT...MAINLY EAST OF THE LOWER COLORADO RIVER VALLEY...AND DECREASE FROM WEST TO EAST DURING THE DAY MONDAY AS MUCH DRIER AIR MOVES IN. TEMPERATURES WILL BE ON A DOWNTREND TODAY THROUGH MONDAY WITH LITTLE CHANGE TUESDAY THROUGH WEDNESDAY. DURING THE LATTER PART OF NEXT WEEK...A LOW PRESSURE SYSTEM IS ANTICIPATED TO DROP SOUTHWARD OVER THE WEST COAST STATES AND SHOULD BRING SOME ADDITIONAL COOLING AND STRONGER WINDS.
