AREA FORECAST DISCUSSION...CORRECTION TO SYNOPSIS
NATIONAL WEATHER SERVICE PHOENIX AZ
305 AM MST WED DEC 21 2011

.SYNOPSIS...
A COUPLE OF RELATIVELY DRY WEATHER DISTURBANCES WILL MOVE INTO THE
REGION FROM THE NORTH THROUGH SATURDAY. THIS WILL SERVE TO KEEP
AFTERNOON TEMPERATURES SEVERAL DEGREES BELOW NORMAL...ALONG
WITH BREEZY CONDITIONS AT TIMES. THE STRONGEST WINDS ARE SLATED FOR
THURSDAY AFTERNOON...ESPECIALLY ALONG THE COLORADO RIVER WHERE
NORTHERLY GUSTS COULD PEAK TO 45 MPH. BREEZY CONDITIONS ARE EXPECTED
AGAIN SATURDAY. LIGHT WINDS WITH A NOTICEABLE WARMING TREND WILL
DEVELOP SUNDAY THROUGH NEXT WEDNESDAY.

&&

.DISCUSSION...
NOTE...VERY WINDY/GUSTY NORTH WINDS DOWN THE COLORADO RIVER VALLEY
THURSDAY AFTERNOON AND EVENING. 45 MPH GUSTS POSSIBLE.

TODAY THROUGH THURSDAY NIGHT...
A QUICK MOVING SHORTWAVE RIDGE/HIGH PRESSURE SYSTEM WILL BUILD OVER
AZ TODAY AND TONIGHT PRODUCING STABLE AND A LITTLE WARMER WEATHER.
THE ONLY CAVEAT IS...WEATHER BALLOON SOUNDINGS CONTINUED TO DETECT
CONSIDERABLE BOUNDARY LAYER MOISTURE...GENERALLY BELOW 7000 THSD FT
MSL...STREWN ACROSS THE SOUTHERN HALF AZ. THIS WILL MAKE FOR MOSTLY
CLOUDY SKIES TODAY/EARLY TONIGHT ACROSS THE HIGHER ELEVATIONS OF
SOUTHERN GILA COUNTY ZONE 24...WITH LITTLE OR NO PRECIP DUE TO
ATMOSPHERIC SINKING MOTIONS RELATED TO THE BUILDING HIGH PRESSURE
SYSTEM.

ON THURSDAY...THE NEXT COLD BUT DRY WEATHER SYSTEM WILL DIVE INTO AZ
FROM THE NORTH. THIS SYSTEM WILL TAKE AN INLAND WESTERN REGION
TRAJECTORY AS IT MOVES SOUTH...SO BOUNDARY LAYER MOISTURE WILL THIN
CONSIDERABLY OVER OUR FORECAST AREA...SOUTHEAST CA TO SOUTH CENTRAL
AZ THURSDAY AFTERNOON. HOWEVER SOME CLOUDINESS IS EXPECTED IN THE
HIGHER MOUNTAINS OF ZONE 24...BUT WITH LITTLE OR NO PRECIP.

THE ONLY WEATHER CONCERN WITH THURSDAYS SYSTEM IS THE POTENTIAL FOR
STRONG NORTH WINDS ALONG THE COLORADO RIVER VALLEY THURSDAY AFTEROON
AND EVENING. 25 TO 35 MPH WINDS...WITH GUSTS TO NEAR 45 MPH ARE
POSSIBLE. A WIND ADVISORY WILL BE POSTED FOR THE COLORADO RIVER
VALLEY FOR THURSDAY AFTERNOON.

A MUCH COLDER AIRMASS WILL ALSO FOLLOW THE COLD FRONT INTO AZ
THURSDAY NIGHT AND FRIDAY. 700 MB TEMPERATURES ARE FORECAST TO FALL
TO NEAR MINUS 10 DEG C OVER PHOENIX BY FRIDAY MORNING...WARMER WEST
OF PHOENIX. THE MINUS 10 DEG C 700 MB ISOTHERM IS A QUICK GUIDE TO
THE POTENTIAL FOR NEAR FREEZING MORNING TEMPERATURES IN THE GREATER
PHOENIX AREA. HOWEVER IN THIS CASE...BREEZY NORTH WINDS AREA WIDE
WILL PRECLUDE THE CONCERN.

FRIDAY AND SATURDAY...
DRY NORTHERLY FLOW ALOFT WILL DEVELOP FRIDAY...BUT ANOTHER DRY AND
WEAK WEATHER DISTURBANCE WILL MOVE IN FROM THE NORTH ON SATURDAY.
BREEZY CONDITIONS WILL CONTINUE SATURDAY.

SUNDAY THROUGH WEDNESDAY...
DRY NORTHWEST FLOW ALOFT AND A WARMER AIRMASS WILL SPREAD BACK INTO
AZ THIS PERIOD. NO WEATHER PROBLEMS EXPECTED.

&&

ACCOMPANIED BY MOSTLY SUNNY SKIES WEDNESDAY AND LIGHT-VARIABLE WIND
THROUGH 03Z THURSDAY.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.

&&

.FIRE WEATHER...
WEDNESDAY THROUGH SATURDAY...
A SERIES OF DRY WEATHER DISTURBANCES WILL MOVE ACROSS THE REGION
THROUGH SATURDAY. THE FIRST SYSTEM WILL GENERATE GUSTY NORTH WINDS

RANGE...THURSDAY AFTERNOON AND EVENING. LIGHTER NORTH WINDS ARE

TREND DOWN INTO THE TEENS DUE TO THE PASSAGE OF A DRY COLD FRONT
THURSDAY AFTERNOON THAT WILL CONTINUE TO SPREAD DRIER AIR OVER THE
REGION FRIDAY AND SATURDAY.
