AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
908 AM MST SAT DEC 8 2007

.SYNOPSIS...A DEEP TROUGH AND STRONG AREA OF LOW PRESSURE WILL BRING
THE CHANCE OF VALLEY RAIN SHOWERS AND MOUNTAIN SNOW SHOWERS TO
SOUTHEAST ARIZONA THROUGH THE MIDDLE OF NEXT WEEK. THIS SYSTEM WILL
ALSO USHER IN MUCH COOLER TEMPERATURES...WITH AFTERNOON HIGHS 5 TO
10 DEGREES BELOW SEASONAL NORMALS. DRIER AND WARMER CONDITIONS ARE
EXPECTED DURING THE LATTER PART OF NEXT WEEK AS HIGH PRESSURE ALOFT
BUILDS ALONG THE WEST COAST.

&&

DISCUSSION...RADAR MOSAIC CURRENTLY SHOWS SCATTERED TO NUMEROUS
SHOWERS ACROSS MAINLY CENTRAL AND EASTERN PORTIONS OF MY FORECAST
AREA. WATER VAPOR IMAGERY SHOWS A DRY SLOT ASSOCIATED WITH THIS
SYSTEM ACROSS THE FAR WESTERN DESERTS OF SW ARIZONA. AS THE DAY
PROGRESSES EXPECT THE SHOWERS TO TAPER OFF FROM WEST TO EAST AS THIS
DRIER AIR BEGINS TO INFLUENCE THE AREA.

MIDNIGHT SHIFT EXTENDED THE SNOW ADVISORY FOR ZONE 19 ABOVE 7000 FT
UNTIL NOON MST...AND THIS SEEMS GOOD. HOWEVER...WILL HAVE TO KEEP AN
EYE ON THE RADAR MOSAIC AND OBSERVATIONS AND DEPENDING ON HOW FAST
THE SHOWERS EXIT TO THE E AND NE...MAY HAVE TO EXTEND IT A BIT
FURTHER IN TIME.

MIDNIGHT SHIFT ALSO UPDATED THE FORECAST TO ADJUST THE POP FORECAST
AND THEIR CHANGES SEEM TO BE REPRESENTATIVE OF THE ONGOING
SITUATION...SO NO CHANGES ARE PLANNED AT THIS TIME.

TEMPERATURE FORECAST SEEMS TO BE RIGHT ON TRACK WITH RESPECT TO
EXPECTED DAYTIME HIGHS...SO NO CHANGES PLANNED THERE EITHER.

&&

.AVIATION...BANDS OF SHOWERS WILL CONTINUE TO PASS THROUGH CENTRAL
AND EASTERN ARIZONA AND WILL EXTEND ACROSS WESTERN NEW MEXICO BY THE
AFTERNOON HOURS. CIGS OF AROUND 3-5KFT AGL WITH VSBYS 3-5SM IN
SHRA/SHSN AND TERRAIN OBSCD CAN BE EXPECTED AS THE FRONT MOVES
THROUGH SOUTHEAST ARIZONA. IMPROVING CONDITIONS CAN BE EXPECTED THIS
AFTERNOON ONCE THE FRONT TRACKS EAST OF THE AREA. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.PREV DISCUSSION...NOT MUCH CHANGE IN THE ONGOING FORECAST THINKING
AS A DEEP TROUGH SETTLES IN ACROSS THE SOUTHWEST THROUGH THE WEEKEND
AND INTO THE MIDDLE PART OF NEXT WEEK. SEVERAL PIECES OF ENERGY WILL
ROTATE THROUGH THIS TROUGH CONTINUING THE COOL AND SHOWERY WEATHER.
AT THIS POINT...IT APPEARS THE BEST SHOT/S AT PRECIPITATION WILL BE
WITH THE FRONTAL PASSAGE EARLY TODAY AND THEN AGAIN LATE IN THE
WEEKEND...DURING THE LATE SUNDAY/MONDAY TIME FRAME. HOWEVER...THERE
WILL BE CHANCE TYPE POPS REFLECTED IN THE GRIDS FOR MUCH OF THE AREA
THROUGH MONDAY. THE EXCEPTION TO THIS WILL BE ACROSS THE FAR WEST
TODAY (RIGHT BEHIND THE FRONTAL BOUNDARY)...AND THEN AREAWIDE LATE
TONIGHT AS A DRY SLOT MOVES ACROSS THE AREA AHEAD OF THE MAIN PIECE
OF ENERGY TO AFFECT THE CWA IN THE LATE SUNDAY/MONDAY TIME FRAME.
THE TRAJECTORY OF THE LAST WAVE TO AFFECT THE AREA ON TUESDAY AND
EARLY WEDNESDAY WILL RESULT IN A CONTINUATION OF THE CHANCE POPS FOR
AREAS NORTH AND EAST OF TUCSON AND SLIGHT CHANCE POPS TO THE WEST.
GUIDANCE VALUES FOR THE TUCSON METRO AREA INDICATE THAT DAYTIME
TEMPERATURES WILL BE 5-10 DEGREES BELOW NORMAL THROUGH WEDNESDAY OF
NEXT WEEK.

BY LATE NEXT WEEK...THE MODELS DEVELOP A EASTERN PACIFIC/WEST COAST
RIDGE. THIS WILL BRING A RETURN TO DRY AND WARMER CONDITIONS...
ALTHOUGH DAYTIME TEMPERATURES ARE EXPECTED TO BE AT OR SLIGHTLY
BELOW SEASONAL VALUES.
