AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
845 PM MST THU OCT 9 2008

.SYNOPSIS...A STRONG LOW PRESSURE SYSTEM WILL MOVE ACROSS THE GREAT
BASIN FRIDAY AND SATURDAY...BRINGING GUSTY WINDS...MUCH COOLER
TEMPERATURES...AND SIGNIFICANT PRECIPITATION. ALTHOUGH IT WILL
DISSIPATE WELL TO THE SOUTH OF ARIZONA...SOME MOISTURE FROM
WEAKENING HURRICANE NORBERT WILL ALSO BE TAPPED BY THE INCOMING
STORM...AND IS LIKELY TO ENHANCE RAINFALL OVER PARTS OF SOUTHEAST
ARIZONA FRIDAY NIGHT AND SATURDAY MORNING. DRIER WEATHER WILL RETURN
BY SATURDAY NIGHT...HOWEVER IT WILL REMAIN ON THE COOL SIDE THROUGH
EARLY NEXT WEEK.

&&

.DISCUSSION...MAINLY CLEAR SKIES ACROSS THE FORECAST AREA THIS
EVENING WITH A FEW LOW/MID CLOUDS OVER NORTHERN PORTIONS OF THE
WHITE MOUNTAINS AND ALONG THE NEW MEXICO BORDER. CLOUD COVER RAPIDLY
DIMINISHING AFTER SUNSET AND EXPECT THIS TREND TO CONTINUE WITH
MOSTLY CLEAR SKIES ON TAP ACROSS THE FORECAST AREA TONIGHT. WILL
MAKE ADJUSTMENTS TO THE GRIDS AND ZONES TONIGHT FOR CLEARING SKIES
AND TO REMOVE ANY MENTION OF POPS THROUGH 12Z FRIDAY. OTHERWISE...
INCREASING MOISTURE WILL PUSH INTO SOUTHEAST ARIZONA ON FRIDAY
RESULTING IN MORE CLOUD COVER AND AN INCREASED POP THREAT...
ESPECIALLY OVER THE EASTERN THIRD OF THE FORECAST AREA. FOR MORE ON
THE UPCOMING SYSTEM TO AFFECT THE REGION THIS WEEKEND PLEASE REFER
TO PREVIOUS DISCUSSION BELOW.
&&

.AVIATION...MOSTLY CLEAR SKIES WILL CONTINUE THROUGH TONIGHT ACROSS
SOUTHEAST ARIZONA. SOUTHWEST WINDS OF 10-20 KTS THIS AFTERNOON WILL
DIMINISH AND BECOME SOUTHERLY AFTER 10/04Z AT 6-12 KTS. CLOUDS WITH
BASES AT OR ABOVE 6K FT AGL WILL INCREASE DURING THE DAY FRIDAY WITH
SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING...ESPECIALLY FROM
KTUS EASTWARD AND CONTINUING THROUGH FRIDAY NIGHT. GUSTY SOUTHWEST
WINDS AT 15-25 KTS WITH GUSTS TO 35 KTS ARE EXPECTED FRIDAY
AFTERNOON...WITH HIGHER GUSTS POSSIBLE NEAR THUNDERSTORMS. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.PREV DISCUSSION...WHILE HURRICANE NORBERT IS CERTAINLY AN
INTERESTING WRINKLE IN OUR FORECAST...HE IS A BIT OF A SIDESHOW
COMPARED TO THE DEEP STORM SYSTEM WHICH WILL WIND UP OVER THE GREAT
BASIN BY FRIDAY NIGHT. MODELS HAVE TRENDED A BIT STRONGER WITH THIS
SYSTEM....WHICH IS NO SURPRISE. THE KEY DIFFERENCE FOR US IS THAT
THE DEVELOPING AGEOSTROPHIC S FLOW ON TOP OF NORBERT/S APPROACH HAS
INDUCED A GULF SURGE TODAY WHICH IS NOW FLOODING ARIZONA WITH LOW
LEVEL MOISTURE MOISTURE. DEWPOINTS HAVE CLIMBED INTO THE 40S AND 50S
TODAY...WITH 60S NOT TOO FAR TO OUR SOUTH. WE THINK IT WILL TAKE A
LITTLE MORE TIME FOR THE MODELS TO RESPOND FULLY TO THIS MOISTURE
INFLUX... ALTHOUGH THE GFS HAS MADE GOOD PROGRESS IN JUMPING POPS
UPWARD SINCE YESTERDAY. WILL BASICALLY GO WITH GFS MOS PLUS 5-10 PCT
DUE TO ITS PERPETUAL DRY BIAS WITH COOL SEASON SYSTEMS. WE HAVE ALSO
BROUGHT POPS INTO SE AZ AS EARLY AS LATE TONIGHT AS HEIGHT FALLS
START TO IMPINGE OF THE STRENGTHENING THETA-E RIDGE. AS SW FLOW AND
SHEAR INCREASES FRI...A FEW TSTMS COULD GET RATHER STRONG...WHICH
THE NEWLY INTRODUCED 5 PCT SEVERE RISK FROM SPC HIGHLIGHTS NICELY.

AS FOR WEAKENING NORBERT...HIS LOW LEVEL CENTER WILL BYPASS US WELL
TO OUR S...IF IT CAN SURVIVE THE TRIP OVER COOLER WATER...
MOUNTAINOUS BAJA...AND INCREASING SW SHEAR. SEE NHC FORECASTS FOR
DETAILS. HOWEVER WE ALSO THINK THE HURRICANE MODELS ARE ONTO
SOMETHING...AND THAT THE MID/UPPER LEVEL PORTIONS OF NORBERT WILL
DECOUPLE AND RACE NE SOMETIME FRI NIGHT OR SATURDAY...SIMILAR TO
WHAT WE SAW WITH JAVIER IN 2004. EVEN IF THIS DOESNT PAN OUT
ENTIRELY...THE APPROACHING HEIGHT FALLS AND ENHANCED JET DYNAMICS
WITH THE GREAT BASIN LOW SHOULD RESULT IN THE HEFTY QPFS OF THE GFS
AND PARTICULARLY THE ECMWF. WILL SEE HOW THE 00Z MODELS REACT WITH
THE CONSIDERABLE RECON DATA WERE RECEIVING THIS AFTERNOON. THE
OTHER CONCERN WITH THIS SYSTEM FRI NIGHT/SAT INVOLVES WIND...AND A
LOT OF IT. IF THE MID LEVEL REMAINS OF NORBERT CAN RIDE NE...THEY
MAY PUT A DENT IN OUR WIND POTENTIAL AS IT REDUCES OUR MID LEVEL
GRADIENTS FOR A TIME. THE BEST JET DYNAMICS AND THERMAL GRADIENTS
ARE ALSO PROGGED TO CROSS N AZ...BUT THEY WILL BE UNCOMFORTABLY
CLOSE...AND GFS BUFR SOUNDINGS HAVE 50-60KT WINDS SCREAMING JUST
ABOVE 700MB OVER TUCSON AT 12Z SAT. SOME OF THAT COULD GET
TRANSFERED DOWN TO AT LEAST MOUNTAINTOP LEVEL BY THE FRONT ITSELF
AND ANY CONVECTION ALONG AND AHEAD OF IT. FOR THIS REASON WE WILL
KEEP WINDS UP ALL NIGHT FRI NIGHT...PARTICULARLY IN THE HIGHER
ELEVATIONS. THE UPCOMING TSTMS...LOCALLY HEAVY RAIN...AND STRONG
WIND POTENTIAL WILL ALL BE HIGHLIGHTED IN AN OMNIBUS HWO THIS
AFTERNOON.

HAVE MADE A COUPLE OF MINOR ADJUSTMENTS IN THE EXTENDED...MAINLY TO
LOWER TEMPS AS A BAGGY TROUGH GETS LEFT BEHIND. WE ARE ALSO A LITTLE
CONCERNED THAT SOME MOISTURE WILL TRY TO WRAP BACK INTO THE LEFTOVER
TROUGH EARLY NEXT WEEK. WE INHERITED SUB-10 PCT POPS ALONG THE NM
BORDER FROM MON-WED WHICH IS QUITE REASONABLE WITH THIS WEAK TROUGH
LINGERING OVER THE SW U.S. AND DEEP MOISTURE NOT TOO FAR TO OUR S/SE.

THANKS TO NHC AND HPC FOR COORDS TODAY.
