AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
230 AM MST FRI APR 25 2014

.SYNOPSIS...A STRONG AND COOL LATE SEASON STORM SYSTEM WILL MOVE
ACROSS THE STATE SATURDAY. GUSTY WINDS WILL BEGIN TO PICK UP ACROSS
THE AREA THIS AFTERNOON WITH WIDESPREAD WINDY CONDITIONS SATURDAY.
EXPECT HIGH WIND GUSTS...ESPECIALLY IN EASTERN AREAS. MUCH COOLER
WITH THIS SYSTEM SATURDAY AS WE ALSO SEE A CHANCE OF SHOWERS AND
THUNDERSTORMS IN VALLEYS...AND SNOW IN HIGHER MOUNTAIN RANGES. DRY
AND WARMER NEXT WEEK.

&&

.DISCUSSION...SOUTHWESTERLY FLOW INCREASING TODAY AHEAD OF AN
APPROACHING PACIFIC STORM SYSTEM. AN UNSEASONABLY COOL AND LOW
LATITUDE LATE SYSTEM WILL PUSH THROUGH THE STATE SATURDAY. BEFORE
THAT HAPPENS WE WILL SEE THE GRADIENT START TO TIGHTEN AS EARLY AS
THIS AFTERNOON FOR FIRE WEATHER CONCERNS.

AS THE SYSTEM PUSHES THROUGH ARIZONA SATURDAY A LATE SEASON COLD
FRONT IS EXPECTED TO REMAIN LARGELY INTACT AS IT SWEEPS ACROSS THE
STATE DURING THE DAY SATURDAY. WINDY CONDITIONS ACROSS THE AREA WITH
WINDY ADVISORY FOR MOST OF THE AREA AND HIGH WIND WATCH FOR EASTERN
COCHISE COUNTY (SUSTAINED WINDS IN EXCESS OF 40MPH). STRONG DYNAMICS
AND COOL MID LEVELS FOR SHOWERS AND ISOLATED THUNDERSTORMS...BEST
CHANCE ACROSS NORTHERN AREAS AND UPSLOPE NEAR HIGHER TERRAIN. SNOW
LEVELS ACTUALLY A FACTOR WITH SNOW AS LOW AS 7K FEET WITH AND JUST
BEHIND THE COLD FRONT SATURDAY. EXPECTING 1-3 INCHES ABOVE 8K FEET
WITH BEST MOISTURE AND DYNAMICS COMING TOGETHER FOR THE WHITE
MOUNTAINS OF NORTHERN GREENLEE AND GRAHAM COUNTIES FOLLOWED CLOSELY
BY MT GRAHAM AND THE CATALINAS NORTH AND NORTHEAST OF TUCSON.

COLD FRONT PUSHING QUICKLY INTO NEW MEXICO BY SATURDAY EVENING WITH
PARTIAL CLEARING FROM THE WEST. AIRMASS POTENTIAL OF OVERNIGHT LOWS
IN COLDEST EASTERN VALLEY LOCATIONS (COCHISE COUNTY) NEAR FREEZING
SUNDAY MORNING...HOWEVER GRADIENT ENHANCED WINDS WILL REMAIN HIGH
ENOUGH IN CONJUNCTION WITH RESIDUAL MOISTURE TO KEEP OVERNIGHT LOWS
FROM REACHING THAT MARK.

STILL BREEZY ESPECIALLY IN EASTERN AREAS SUNDAY...BUT NOT NEARLY AS
STRONG AS SATURDAY. DAYTIME HIGHS DOWN 15-20 DEGREES OVER THE
WEEKEND...AROUND 10-14 DEGREES BELOW CLIMO FOR A CHANGE.

REBOUND IN HEIGHT AND THICKNESSES AS THE FRONT SIDE OF EASTERN
PACIFIC RIDGE TRIES TO NUDGE IN MONDAY AND TUESDAY. POTENTIAL OF
SOME ENERGY SPLITTING BACK INTO THE DESERT SOUTHWEST AROUND MID WEEK
WITH AN OMEGA CONFIGURATION OF WEST COAST RIDGE. NOT SURE HOW FAR
WEST THIS WELL DEVELOP BUT IT COULD MEAN ANOTHER ROUND OF HIGH BASED
THUNDERSTORM ACTIVITY.

&&

.AVIATION...WESTERLY TO SOUTHWESTERLY FLOW ALOFT WITH PATCHES OF
THICKENING CIRRUS CLOUDS TODAY. MID CLOUDS INCREASING AND LOWERING
DURING THE DAY SATURDAY WITH SCT -SHRA/-TSRA DEVELOPING SATURDAY.
DIURNAL TERRAIN DRIVEN WINDS LESS THAN 10 KTS THIS
MORNING...INCREASING THIS AFTERNOON BETWEEN 17-22 KTS WITH GUSTS TO
30 KTS. THE STRONGEST WINDS WILL BE ACROSS SANTA CRUZ AND COCHISE
COUNTIES. BECOMING WINDIER SATURDAY AS A COLD FRONT PUSHES ACROSS
THE AREA. THE AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...A PACIFIC STORM SYSTEM MOVING INTO CALIFORNIA TODAY
WILL RESULT IN BREEZY TO LOCALLY WINDY CONDITIONS ACROSS SOUTHEAST
ARIZONA...ESPECIALLY SANTA CRUZ AND COCHISE COUNTIES. THESE WINDS
COMBINED WITH THE PREVAILING DRY AIRMASS/LOW HUMIDITIES SHOULD
RESULT IN SOME LOCATIONS MEETING AND EXCEEDING RED FLAG CRITERIA...
ESPECIALLY ACROSS EASTERN SANTA CRUZ AND SOUTHERN COCHISE COUNTIES.
THEREFORE...A RED FLAG WARNING IS IN EFFECT FROM 2 PM TO 7 PM MST
TODAY FOR AREAS ACROSS SOUTHERN FIRE ZONE 152 AND SOUTHEASTERN FIRE
ZONE 151.

THE STORM SYSTEM WILL THEN MOVE ACROSS ARIZONA SATURDAY RESULTING
IN WINDY CONDITIONS ACROSS SOUTHEAST ARIZONA. THIS SYSTEM WILL
IMPORT DEEPER MOISTURE...RESULTING IN SOME VALLEY RAIN AND MOUNTAIN
SNOW SATURDAY AFTERNOON AND EARLY EVENING. ALTHOUGH THE INCREASED
MOISTURE AND CLOUD COVER SHOULD HELP KEEP RED FLAG CONDITIONS AT BAY
FOR MOST AREA...MOISTURE WILL BE SLOW TO REACH LOCATIONS ACROSS
EASTERN COCHISE...SOUTHEAST GRAHAM AND SOUTHERN GREENLEE COUNTIES.
THEREFORE...A RED FLAG WARNING IS IN EFFECT FROM 11 AM TO 7 PM MST
SATURDAY FOR THE EASTERN HALF OF FIRE ZONE 152.

&&
