AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
325 AM MST MON DEC 22 2008

.SYNOPSIS...THE PLEASANT AND QUIET WEEKEND WILL GIVE WAY TO A VERY
ACTIVE UNSETTLED WEATHER PATTERN THIS WEEK. DAYTIME TEMPERATURES
WILL CONTINUE TO WARM TODAY BEFORE A DRAMATIC WEATHER CHANGE TAKES
PLACE MONDAY NIGHT INTO TUESDAY WHICH WILL LAST THROUGH THE
CHRISTMAS HOLIDAY PERIOD.

&&

.DISCUSSION...THE QUIET WEATHER WEEKEND WILL CONTINUE FOR ONE MORE
DAY BEFORE A VERY ACTIVE AND WET PERIOD IMPACTS THE AREA FOR THE
REST OF THE WEEK. THE FIRST IN A SERIES OF WEATHER SYSTEMS IS
CURRENTLY WELL TO OUR NORTHWEST WITH CENTER OF LOW OFF OREGON COAST.
CLOUDS ALREADY ARE WORKING ACROSS NORTHERN ARIZONA THIS MORNING AND
THEY SHOULD GRADUALLY SAG SOUTH ACROSS SOUTHERN ARIZONA TODAY. THIS
FIRST SYSTEM WILL SWEEP ACROSS THE STATE LATER THIS EVENING INTO
TUESDAY. IN THE PROCESS...IT WILL PICK UP SOME MARINE LAYER MOISTURE
AND COMBINED WITH FAIRLY IMPRESSIVE UPPER DYNAMICS AND UPSLOPE
FLOW...WILL PRODUCE A GOOD AMOUNT OF SNOW IN THE MOUNTAINS. WE HAVE
UPGRADED THE WINTER STORM WATCH TO WINTER STORM WARNING FOR THE
WHITES WHERE THEY WILL GET UP TO A FOOT BY TUESDAY AFTERNOON AND A
WINTER WEATHER ADVISORY ABOVE 7000 FEET FOR THE MOUNTAINS OF EASTERN
PIMA AND GRAHAM COUNTIES. PLEASE REFER WINTER STORM PRODUCT UNDER
AWIPS HEADER PHXWSWTWC OR WMO HEADER WWUS45 FOR MORE INFORMATION.
HIGH TEMPERATURES TUESDAY WILL BE 8 TO 12 DEGREES COLDER THAN TODAY.

CLEARING FROM WEST TO EAST TUESDAY NIGHT INTO WEDNESDAY AS SYSTEM #2
DEEPENS/BECOMES CLOSED LOW OFF CENTRAL CALIFORNIA COAST. HOWEVER AS
THIS SYSTEM CONTINUES TO DIVE TOWARD SOUTHERN CALIFORNIA ON
WEDNESDAY IT WEAKENS CONSIDERABLY/BECOMES AN OPEN WAVE BEFORE MOVING
THROUGH ARIZONA LATE WEDNESDAY NIGHT INTO THURSDAY. THERE ARE STILL
SOME TIMING DIFFERENCES BETWEEN GFS/ECMWF MODELS...WITH GFS STILL A
BIT MORE PROGRESSIVE THAN THE ECMWF. I HAVE DECIDED TO SHOW A
SIGNIFICANT POP BREAK BETWEEN SYSTEM #1 AND #2 WITH LOWER POPS
ACROSS THE AREA.

SYSTEM #2 WILL SWEEP ACROSS THE STATE LATE WEDNESDAY NIGHT INTO
CHRISTMAS DAY AND BRING ANOTHER ROUND OF VALLEY RAIN AND MOUNTAIN
SNOW. ACCUMULATIONS WILL BE MUCH LESS WITH THIS SYSTEM THAN #1.

NOT MUCH OF A BREAK BEFORE SYSTEM #3 IMPACTS THE AREA EARLY FRIDAY
WITH ANOTHER CHANCE OF VALLEY RAIN AND MOUNTAIN SNOW. THIS SYSTEM
WILL BE THE COLDEST OF THE THREE WITH LOWER SNOW LEVELS AND SNOW
ACCUMULATIONS POSSIBLY IN LINE WITH WHAT WE ARE FORECASTING WITH
SYSTEM #1.

IF MODELS ARE RIGHT...STORM #3 WILL BE EAST OF THE STATE EARLY
SATURDAY MORNING WITH NEXT WEEKEND BEING DRY BUT COOL.

&&

.AVIATION...A CLEAR SKY WILL PREVAIL THROUGH ABOUT MID-MORNING
BEFORE MID TO HIGH LEVELS CLOUDS PUSH IN FROM THE WEST. CLOUD DECKS
WILL GRADUALLY LOWER THIS EVENING AS SHOWERS BEGIN TO DEVELOP.
CEILINGS WILL BE IN THE 8-10 KFT RANGE AFTER MIDNIGHT TUESDAY AS
AREAL COVERAGE OF SHOWERS INCREASE. SURFACE WINDS GENERALLY LESS
THAN 10 KTS THIS MORNING...THEN SLY/SWLY 5-15 KTS DURING THE 18Z-23Z
PERIOD TODAY. AVIATION DISCUSSION NOT AMENDED FOR TAF AMENDMENTS.
