AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
350 AM MST TUE DEC 22 2009

.SYNOPSIS...A STRONG PACIFIC STORM SYSTEM WILL MOVE ACROSS THE GREAT
BASIN TODAY...THEN ACROSS THE SOUTHERN ROCKIES TONIGHT INTO
WEDNESDAY. THIS SYSTEM WILL BRING COOLER AND WINDY CONDITIONS
TODAY...FOLLOWED BY VALLEY RAIN AND MOUNTAIN SNOW THIS EVENING INTO
WEDNESDAY MORNING. DECREASING CLOUDS AND MUCH COOLER WEDNESDAY THEN
WIDESPREAD FREEZING TEMPERATURES WEDNESDAY NIGHT. EXPECT DRY
CONDITIONS CHRISTMAS EVE INTO THIS WEEKEND THOUGH DAYTIME
TEMPERATURES REMAINING BELOW NORMAL.

&&

.DISCUSSION...UPPER LOW OVER SRN WASHINGTON AT THIS TIME WILL DIG
SEWD ACROSS THE GREAT BASIN REGION TODAY...THEN MOVE ESEWD ACROSS
NRN AZ TONIGHT AND TO THE TX PANHANDLE WED. MAIN IMPACT AHEAD OF THE
SYSTEM TODAY WILL BE INCREASING SLY/SWLY WINDS. HAVE CONSIDERED
ISSUANCE OF WIND ADVISORY PARTICULARLY FROM THE TUCSON METRO AREA
SWD/EWD FOR THIS AFTERNOON AND EVENING. AT THIS TIME APPEARS A FEW
LOCALES WOULD ACHIEVE ADVISORY CRITERIA FOR JUST A COUPLE OF HOURS.
THUS WIDESPREAD AND LONG-LIVED CONDITIONS ARE NOT EXPECTED TO OCCUR
AT LEAST AT THIS TIME. HOWEVER...DAYSHIFT WILL NEED TO MONITOR
CONDITIONS AND EVALUATE FURTHER AFTER RECEIPT OF VARIOUS 22/12Z NWP
MODEL GUIDANCE.

THE FOCUS THEN SHIFTS TOWARD PRECIP POTENTIAL. 22/00Z NAM/GFS/ECMWF
STILL INDICATE THAT THE BEST CHANCE OF MEASURABLE PRECIP ACROSS MUCH
OF THIS FORECAST AREA IS THIS EVENING INTO WED MORNING. THUS WILL
MAINTAIN SNOW ADVISORY ACROSS NRN GREENLEE/GRAHAM COUNTIES ABOVE
7000 FEET VALID FROM 5 PM THIS AFTERNOON TO 6 AM MST WED. VERY TIGHT
MID-LEVEL GRADIENT AS WELL AS MODEL PROGGED 40-55 KT 700 MB WINDS
JUSTIFIES FORECAST OF BLOWING SNOW AT HIGHER ELEVATIONS. SEE AWIPS
PIL PHXWSWTWC /WMO HEADER WWUS45 KTWC/ FOR DETAIL.

PRECIP TO END MOST SECTIONS BY WED AFTERNOON WITH DECREASING CLOUDS
OR MOSTLY SUNNY SKIES. HOWEVER...STILL ENOUGH MOISTURE TO JUSTIFY A
CHANCE OF SNOW SHOWERS VICINITY WHITE MOUNTAINS WITH ADDITIONAL SNOW
ACCUMULATIONS OF JUST AN INCH OR SO ABOVE 7000 FEET. CLEAR SKIES AND
LIGHT WIND WED NIGHT WILL PRODUCE WIDESPREAD FREEZING TEMPS ACROSS
MUCH OF SE AZ. DRY CONDITIONS EXPECTED AREAWIDE THUR-SUN.

THEREAFTER...DIFFERENCES EXISTED BETWEEN THE 22/00Z GFS/ECMWF
SOLUTIONS WITH REGARD TO WRN CONUS TROUGH EARLY NEXT WEEK. ECMWF
SOLUTION WAS DEEPER WITH TROUGH VERSUS GFS SOLUTION THUS RESULTING
IN LOW-CONFIDENCE FOR SUN NIGHT-MON. AT ANY RATE...WILL OPT FOR A
SLIGHT CHANCE OF RAIN AND HIGHER-ELEVATION SNOW SHOWERS NERN
SECTIONS SUN NIGHT...THEN LOW-GRADE POPS FOR AREAS EAST OF TUCSON
MON. WOULD NOT BE SURPRISED IF REALITY IS REALIZED WITH A DEEPER AND
SLOWER SYSTEM THAT EVENTUALLY BRINGS SIGNIFICANT PRECIP TO THE AREA
SOMETIME EARLY NEXT WEEK.

COOLER TODAY THEN QUITE COOL WED WITH DAYTIME TEMPS ABOUT 10-15 DEGS
OR SO BELOW NORMAL. SLIGHTLY WARMER THUR WITH HIGH TEMPS DURING THE
CHRISTMAS DAY-MON PERIOD REMAINING GENERALLY BELOW NORMAL.
