AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
325 AM MST WED JAN 20 2010

.SYNOPSIS...A STRONG STORM SYSTEM WILL MOVE INTO THE AREA TODAY
THROUGH SATURDAY MORNING. THIS WILL RESULT IN STRONG AND POTENTIALLY
DAMAGING WINDS THIS AFTERNOON AND TONIGHT IN ADDITION TO VALLEY RAIN
AND MOUNTAIN SNOW. BY FRIDAY NIGHT INTO EARLY SATURDAY SNOW LEVELS
WILL LOWER WITH POSSIBLE ACCUMULATING SNOWS ACROSS LOWER ELEVATIONS
SOUTH AND EAST OF TUCSON. IMPROVING WEATHER CAN BE ANTICIPATED BY
SUNDAY AND MONDAY BEFORE ANOTHER...MUCH WEAKER SYSTEM APPROACHES
FROM THE EASTERN PACIFIC.

&&

.DISCUSSION...MULTI FACETED WEATHER SCENARIO NOW TAKING SHAPE ACROSS
SOUTHEAST ARIZONA AS A STRONG LOW PRESSURE ACROSS THE EASTERN
PACIFIC MOVES INTO THE AREA. THE BIGGEST STORY WITH THE GREATEST
PUBLIC IMPACT AREAWIDE WILL BE THE WIND EVENT THAT IS GOING TO MOVE
IN STARTING THIS AFTERNOON AND CONTINUING THROUGH TONIGHT. MODELS
REMAIN CONSISTENT SHOWING AN 850MB SOUTHERLY LOW LEVEL JET WITH
WINDS OF 70 TO 80 MPH MOVING IN FROM THE WEST THIS AFTERNOON AND
SWEEPING EAST TONIGHT. THIS WILL RESULT IN WINDS PICKING UP RATHER
DRAMATICALLY THIS AFTERNOON. ALTHOUGH WE'LL LOSE THE FAVORABLE
DIURNAL MIXING TONIGHT...THIS IS WHEN THE STRONGEST GRADIENT WILL BE
ACROSS THE AREA. AS THE ASSOCIATED COLD FRONT MOVES THROUGH WITH
PERHAPS SOME ISOLATED THUNDERSTORMS THIS SHOULD BE ENOUGH TO RESULT
IN DOWNWARD MOMENTUM TRANSFER OF VERY STRONG WINDS.
BOTTOMLINE...WE'RE LOOKING AT AN UNUSUAL HIGH WIND EVENT WITH
SUSTAINED WINDS OF 35 TO 45 MPH WITH LOCALIZED GUSTS TO 65 MPH AND
PERHAPS EVEN HIGHER GUSTS IN/NEAR MOUNTAINS. HAVE GONE WITH A HIGH
WIND WARNING AREAWIDE TO COVER THESE IMPACTS.

THE NEXT BIG STORY WITH THIS STORM WILL BE ITS ASSOCIATED
PRECIPITATION IMPACTS. IN THE SHORT TERM...WE'LL CONTINUE TO SEE
SCATTERED LIGHT SHOWER ACTIVITY ACROSS THE FORECAST AREA WITH THE
BULK OF THE PRECIPITATION TO OUR NORTH AND WEST EARLY THIS MORNING.
THIS WILL GRADUALLY TRANSLATE SOUTH AND EAST TODAY AS
ADDITIONAL ENERGY CONTINUES TO MOVE IN FROM THE WEST. THE BULK OF
THE PRECIPITATION IS LIKELY TONIGHT INTO EARLY FRIDAY MORNING AS
DEEP MOISTURE COINCIDES STRONG LIFT AND DYNAMICS AS THE COLD FRONT
MOVES ACROSS THE AREA. QPF AMOUNTS OF 0.75 TO 1.5 INCHES IN THE
VALLEYS LOOK LIKE A GOOD BET THROUGH FRIDAY WITH THE EXCEPTION OF
SOME UNLUCKY RAIN SHADOWED LOCATIONS WHICH WILL SEE LESS. THE
MOUNTAINS ARE LIKELY TO SEE 1 TO 2 INCHES WITH EVEN HIGHER AMOUNTS
ACROSS FAVORED UPSLOPE LOCATIONS IN THE WHITE MOUNTAINS. NOW
REGARDING SNOWFALL...EXPECT SNOW LEVELS WHICH ARE CURRENTLY ABOUT
6500 FEET TO INCREASE INTO THIS EVENING TO ABOUT 8000 FEET BEFORE
LOWERING TO ABOUT 5500 FEET FRIDAY MORNING. WILL GO AHEAD AND HOIST
A BLIZZARD WARNING STARTING 5 PM TODAY THROUGH 11 AM FRIDAY FOR
LOCATIONS ABOVE 7000 FEET. SNOW AMOUNTS OF 10 TO 20 INCHES ABOVE
7000 FEET ARE LIKELY WITH 20 TO 30 INCHES IN THE WHITE MOUNTAINS
ABOVE 7000 FEET. ALTHOUGH THERE WILL BE SOME SNOW WITH PERHAPS A FEW
INCHES DURING THE DAYTIME HOURS...FELT THE MOST WIDESPREAD BLIZZARD
IMPACTS LIKELY TONIGHT INTO FRIDAY MORNING. AS THE SNOW LEVELS
INCREASE FOR A TIME THIS EVENING WITH HEAVY PRECIPITATION IN THE
MOUNTAINS...COULD SEE SOME SMALL STREAM ISSUES. WILL UPDATE
ESF/FLOOD POTENTIAL OUTLOOK FOR THIS.

THERE COULD BE A BRIEF BREAK IN THE ACTION SO TO SPEAK BEFORE A
SECONDARY SHORTWAVE PUSHES THROUGH THE FORECAST AREA FRIDAY NIGHT.
THIS WILL BE ANOTHER ISSUE TO DEAL WITH AS MUCH COLDER AIR SETTLES
INTO THE AREA WITH DEEP MOISTURE REMAINING IN PLACE. 00Z MODELS ARE
NOW IN PRETTY GOOD AGREEMENT ABOUT THIS SYSTEM WITH SNOW LEVELS
BECOMING QUITE LOW OVERNIGHT INTO SATURDAY MORNING. THIS SCENARIO
COULD LEAD TO A COUPLE OF INCHES OF SNOW IN VALLEY LOCATIONS SOUTH
AND EAST OF TUCSON WITH PERHAPS THE SNOW LEVEL AS LOW AS THE
FOOTHILLS IN TUCSON EARLY SATURDAY MORNING. EVEN WITH SNOW LEVELS
THIS LOW...ACCUMULATING SNOW SHOULD MAINLY BE ABOVE 4000 FEET. WILL
LET THE DAYSHIFT TAKE ANOTHER LOOK AT THE MODELS AND CONSIDER A
WINTER STORM WATCH DUE TO THE LOW ELEVATION NATURE OF THIS EVENT.

THE TROUGH WILL BEGIN TO MOVE EAST ON SATURDAY WITH PRECIPITATION
CHANCES GRADUALLY TAPERING OFF AS DRIER NORTHWEST FLOW IN. SOME
RIDGING WILL THEN MOVE IN SUNDAY AND MONDAY BEFORE ANOTHER WEAKER
SHORTWAVE MOVES IN TUESDAY INTO WEDNESDAY. HAVE UPPED THE POPS ON
THIS FORECAST PACKAGE INTO THE CHANCE CATEGORY WITH THIS NEXT SYSTEM.

&&

.AVIATION...STRONG STORM SYSTEM ENTERING THE AREA TODAY INTO FRIDAY
BRINGING HIGH WINDS AND LOW CEILINGS WITH SHOWERS NOT TO MENTION
OBSCURED MOUNTAINS. SOUTHERLY SURFACE WINDS IN EXCESS OF 25 KNOTS
WITH GUSTS OVER 50 KNOTS WILL BE POSSIBLE AT TERMINAL SITES FROM 18Z
TODAY THRU 15Z FRIDAY. EXPECT BKN-OVC CEILINGS LOWERING WITH
MVFR/MTN OBSCURATION CONDITIONS DEVELOPING AREAWIDE AFTER 15Z.
ADDITIONALLY...EXPECT VISIBILITIES TO BE AROUND 2-6SM IN RA/SHRA AT
TIMES.

&&

.FIRE WEATHER...NO FIRE WEATHER CONCERNS AT THIS TIME.
