AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
235 AM MST SUN NOV 16 2014

.SYNOPSIS...A WEATHER SYSTEM MOVING IN FROM THE NORTH WILL RESULT IN
A CHANCE OF VALLEY RAIN SHOWERS AND MOUNTAIN SNOW MAINLY NORTHEAST
OF TUCSON SUNDAY ALONG WITH GUSTY NORTHWEST WINDS AT TIMES. THIS
SYSTEM WILL BE FOLLOWED BY COOLER THAN AVERAGE TEMPERATURES FOR THE
FIRST HALF OF THE WORK WEEK WITH SOME BELOW FREEZING READINGS BOTH
MONDAY AND TUESDAY MORNINGS.

&&

.DISCUSSION...WATER VAPOR IMAGERY AND 16/00Z UPPER-AIR PLOTS SHOW
THE SYSTEM THAT WILL BRING SHOWERS TO PORTIONS OF GRAHAM AND
GREENLEE COUNTIES TODAY...CURRENTLY EXTENDS EAST TO WEST ACROSS
SOUTHERN UTAH AND NEVADA. THIS SYSTEM HAS MOVED RAPIDLY SOUTH DURING
THE PAST SEVERAL HOURS AND WILL CONTINUE TO DO SO THIS MORNING. IR
SATELLITE IMAGERY SHOWS EXTENSIVE CLOUDINESS ASSOCIATED WITH THIS
SYSTEM THAT COVERS SOUTHERN UTAH...NORTHERN ARIZONA...MUCH OF
COLORADO AND NORTHERN NEW MEXICO. THE SYSTEM IS EXPECTED TO SWING
ACROSS NORTHEAST ARIZONA AND INTO NORTHERN NEW MEXICO DURING THE
NEXT 12 HOURS OR SO. DURING THAT TIME EXPECT SHOWERS TO DEVELOP OVER
THE NORTHEASTERN QUADRANT OF ARIZONA WITH THE WHITE MOUNTAINS OF
NORTHERN GREENLEE AND GRAHAM COUNTIES RECEIVING RAIN MIXED WITH SNOW
IN THE PROCESS. NOT A SIGNIFICANT AMOUNT OF SNOW...JUST A COUPLE OF
INCHES OR SO ON THE HIGHEST MOUNTAIN LOCATIONS OF GRAHAM AND
GREENLEE COUNTIES...WITH RAIN IN VALLEY LOCATIONS. IN ADDITION TO
THE SHOWERS...EXPECT WINDS TO INCREASE AS THIS SYSTEM MOVES ACROSS
THE REGION. THE AREAS TO SEE THE MOST SIGNIFICANT WINDS WILL BE IN
THE GILA RIVER VALLEY...INCLUDING THE TOWN OF SAFFORD WHERE WINDS
WILL BE IN THE HIGH END OF BREEZY TO LOW END OF WINDY CATEGORIES...
BUT BELOW WIND ADVISORY CRITERIA. BY LATE THIS AFTERNOON THE SYSTEM
WILL HAVE MOVED TO THE TEXAS PANHANDLE WITH THE RAIN CHANCES FOR
EAST CENTRAL ARIZONA DROPPING CONSIDERABLY...WITH NO THREAT BY EARLY
THIS EVENING.

THIS SYSTEM WILL CONTINUE TO MOVE EASTWARD THROUGH THE EARLY PART OF
THE WEEK BECOMING ABSORBED INTO THE LARGE LOW PRESSURE SYSTEM OVER
THE GREAT LAKES REGION WITH THE ASSOCIATED TROUGH THAT WILL COVER A
LARGE PART OF THE EASTERN STATES. MEANWHILE...RIDGING WILL BUILD IN
ACROSS THE WEST COAST MONDAY AND INTO THE WESTERN STATES ON TUESDAY.
THE AFOREMENTIONED TROUGH PASSAGE WILL USHER IN COLD AIR BEHIND IT
FOR FREEZING TO SUB-FREEZING LOW TEMPERATURES EXPECTED FOR MONDAY
AND TUESDAY MORNINGS...ALBEIT THE COLDEST MORNING WILL BE TUESDAY.
THAT SAID...THE FREEZE WATCH FOR MONDAY AND TUESDAY MORNINGS HAVE
BEEN UPGRADED TO FREEZE WARNINGS. THESE WILL BE IN EFFECT STARTING
FROM 2 AM TO 8 AM MST FOR BOTH MONDAY AND TUESDAY MORNINGS FOR MOST
OF THE VALLEY LOCATIONS OF GRAHAM AND COCHISE COUNTIES. SEE THE
WATCH/WARNING/ADVISORY SECTION BELOW. ONE CAVEAT TO THIS IS THAT THE
FREEZE WARNING FOR TUESDAY MORNING MAY NEED TO BE UPGRADED TO A
'HARD' FREEZE WARNING. WILL LET SUBSEQUENT SHIFTS DECIDE IF THAT IS
THE ROUTE WE SHOULD TAKE. WOULD LIKE TO SEE HOW COLD WE ACTUALLY GET
MONDAY MORNING BEFORE MAKING A DECISION FOR TUESDAY.

BY MIDWEEK NEARLY ZONAL FLOW WILL DEVELOP ACROSS THE SOUTHWEST WITH
WEAK DISTURBANCES MOVING WEST TO EAST ACROSS PORTIONS OF THE
SOUTHWEST THROUGH LATE WEEK AND INTO THE WEEKEND. HOWEVER...THERE
ARE SOME TIMING DIFFERENCES AMONG THE MODELS...BUT MOSTLY DRY
WEATHER IS EXPECTED. THERE COULD BE A SMALL THREAT FOR SHOWERS LATE
SATURDAY INTO SUNDAY AS A COUPLE OF DISTURBANCES MOVE BY TO OUR
NORTH. I INHERITED SLIGHT CHANCES FOR MOUNTAIN LOCATIONS DURING THIS
TIME FRAME AND THIS SEEMS REASONABLE. THE 15/12Z RUN OF THE ECMWF
WAS RATHER WET...BUT THE 16/00Z RUN HAS BACKED OFF SIGNIFICANTLY...
BUT STILL SHOWS A SMALL THREAT FOR SATURDAY INTO SUNDAY. GIVEN THIS
UNCERTAINTY...WILL JUST KEEP THE SLIGHT CHANCE OF MOUNTAIN SHOWERS
THAT I INHERITED.

FOR TUCSON...HIGH TEMPS WILL GENERALLY RANGE FROM 3 TO 5 DEGS BELOW
NORMAL TODAY AND MONDAY...THEN NEAR NORMAL FOR TUESDAY.
THEREAFTER...HIGHS AROUND 2 TO 4 DEGS ABOVE NORMAL. LOW TEMPERATURES
EXPECTED TO BE 5 TO 8 DEGS BELOW NORMAL FOR MONDAY AND TUESDAY
MORNINGS RESPECTIVELY...WITH NEAR NORMAL LOWS FOR WEDNESDAY.
THEREAFTER...LOWS 3 TO 5 DEGS ABOVE NORMAL EACH MORNING.

&&

.AVIATION...VALID THRU 17/12Z.
EXPECT SOME LOWER TO MID LEVEL CLOUDS TO SLIDE SE ACROSS AREAS NORTH
AND EAST OF KTUS TODAY WITH SCT-BKN CLOUDS AT 5-9K FT AND SCT-BKN
LAYERS ABV.  ISOLATED TO SCATTERED VALLEY -SHRA ESPECIALLY NE OF
KSAD WITH MOUNTAIN SNOW LIKELY NE OF KSAD.  CLOUDS AND SHOWER
ACTIVITY WILL MOVE SE OF THE AREA BY 17/00Z WITH CLEAR SKIES
THEREAFTER. SURFACE WINDS INCREASING AFTER 16/15Z BECOMING WLY/NWLY
AT 10-20 KTS WITH THE STRONGEST WINDS EAST OF KTUS...ESPECIALLY DOWN
THE GILA RIVER VALLEY.  WIND EASING TO 6-12 KTS AND BECOMING NE AFT
17/03Z THEN BECOMING EAST BY 17/12Z.  AVIATION DISCUSSION NOT
UPDATED FOR TAF AMENDMENTS.  CERNIGLIA

&&

.FIRE WEATHER...A WEATHER SYSTEM DIVING SE ACROSS THE AREA TODAY
WILL BRING ISOLATED TO SCATTERED VALLEY SHOWERS MAINLY NORTHEAST OF
TUCSON TODAY WITH MOUNTAIN SNOW LIKELY IN THE WHITE MOUNTAINS. IT
WILL ALSO GENERATE GUSTY WEST TO NORTHWEST WINDS ACROSS THE EASTERN
HALF OF THE FORECAST AREA ESPECIALLY AROUND SAFFORD WHERE WIND
SPEEDS OF 15-25 MPH WITH GUSTS TO AROUND 30 MPH ARE POSSIBLE DOWN
THE GILA RIVER VALLEY.  COLDER AND VERY DRY AIR WILL SETTLE IN OVER
THE AREA MONDAY THROUGH TUESDAY WITH EASTERLY WINDS AT TIMES.  THEN
WEDNESDAY ONWARD...DRY WEATHER WILL CONTINUE WITH SEASONALLY NORMAL
TEMPERATURES AND TYPICAL DIURNAL WINDS.  CERNIGLIA
