AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
240 AM MST TUE APR 14 2009

.SYNOPSIS...THE NEXT PACIFIC STORM SYSTEM WILL ARRIVE IN THE GREAT
BASIN LATER TODAY AND WEDNESDAY...PRODUCING ANOTHER ROUND OF STRONG
GUSTY WINDS ACROSS SOUTHEAST ARIZONA. THIS STORM SYSTEM WILL ALSO
BRING COOLER TEMPERATURES...WITH HIGH TEMPERATURES BELOW NORMAL
WEDNESDAY AND ESPECIALLY THURSDAY. EXPECT A SLIGHT CHANCE OF RAIN
AND SNOW SHOWERS FOR AREAS NORTHEAST OF THE TUCSON METRO AREA
WEDNESDAY AFTERNOON AND WEDNESDAY NIGHT. A STRONG RIDGE OF HIGH
PRESSURE WILL THEN BUILD OVER SOUTHEAST ARIZONA THIS WEEKEND INTO
NEXT WEEK...WITH MUCH WARMER TEMPERATURES EXPECTED.

&&

.DISCUSSION...THE MAIN FORECAST CONCERN WILL BE THE WIND TODAY AND
WEDNESDAY AS THE NEXT PACIFIC STORM SYSTEM ENTERS THE GREAT BASIN
REGION. MODELS STILL SHOWED THE BULK OF THE MOISTURE NEEDED FOR
PRECIPITATION REMAINING NORTH OF THE AREA AS THE UPPER LOW TRACKS
THROUGH NEVADA AND UTAH. THEREFORE...GENERALLY DRY CONDITIONS AND A
PERIOD OF BREEZY TO WINDY WEATHER CAN BE ANTICIPATED LATER TODAY
INTO EARLY THURSDAY. BEST CHANCE OF PRECIPITATION...ALTHOUGH
LOW...WILL BE MAINLY NORTHEAST OF TUCSON AND IN THE WHITE MOUNTAINS
WEDNESDAY AFTERNOON AND EVENING AS THE UPPER LOW MOVES OVER SOUTHERN
UTAH. THE SYSTEM WILL ALSO USHER IN SOME COOLER AIR WEDNESDAY AND
THURSDAY WITH PROJECTED HIGH TEMPERATURES DROPPING 8 TO 10 DEGREES
ON WEDNESDAY FROM READINGS TODAY. ANOTHER 4 TO 6 DEGREES OF COOLING
CAN BE EXPECTED ON THURSDAY FROM PROJECTED HIGHS ON WEDNESDAY.
PLEASE REFER TO THE FIRE WEATHER SECTION BELOW FOR MORE DETAILS ON
THE UPCOMING WIND.

LATEST MODELS TRACK THE SYSTEM INTO THE PLAIN STATES FRIDAY...WITH A
RIDGE OF HIGH PRESSURE ALOFT BUILDING IN BEHIND IT SATURDAY INTO
EARLY NEXT WEEK. THIS HIGH PRESSURE RIDGE WILL RESULT IN WELL ABOVE
NORMAL HIGH TEMPERATURES AROUND SUNDAY AND MONDAY.

&&

.FIRE WEATHER...A STRONG LOW PRESSURE SYSTEM WILL MOVE SOUTH ACROSS
THE WESTERN STATES TODAY AND WEDNESDAY...RESULTING IN SOME LOCATIONS
ACROSS SE AZ SEEING BREEZY TO WINDY CONDITIONS TODAY...THEN BECOMING
MORE WIDESPREAD ON WEDNESDAY. FORECAST PROBLEMS LIE WITH SOME SNOW
REMAINING ABOVE 6000 FT FROM THE LAST STORM SYSTEM...BORDERLINE FUEL
MOISTURES AND BORDERLINE FORECAST MIN RH VALUES...AS WELL AS THE
NATURE OF THE WINDS TUESDAY VS WEDNESDAY. PRIMARY FOCUS FOR WINDS
TUESDAY FROM CURRENT MODEL DATA SEEMS TO BE SOUTHERN 148 (COCHISE
AND SANTA CRUZ...WITH A FEW SPOTS IN SOUTHERN EASTERN PIMA COUNTY)
AND SOUTHERN 147 (CENTRAL AND WESTERN PIMA COUNTY). DATA FOR
NORTHERN 147 (SE PINAL COUNTY) IS CLOSE...BUT NOT ENTIRELY
CONVINCING...AND DATA FOR GRAHAM AND GREENLEE COUNTIES WOULD IMPLY
SOME INCREASED WIND SPEEDS...BUT NOTHING WITHIN CRITICAL PARAMETERS.
THE PRESENCE OF A WILDFIRE IN THE BLUE RIVER VALLEY DOES GIVE PAUSE
THOUGH. WITH SO MUCH BEING BORDERLINE...WILL SIDE WITH CAUTION AND
GO AHEAD AND UPGRADE EXISTING FIRE WEATHER WATCH TO A RED FLAG FOR
THIS AFTERNOON AND EARLY EVENING. LOOKING OVER DATA FOR
WEDS...STRONGEST WINDS WILL REMAIN IN EASTERN PORTIONS OF THE CWA.
RH VALUES FOR FIRE WEATHER ZONES 146 AND 147 (GRAHAM COUNTY NORTH OF
THE GILA...NORTHERN GREENLEE COUNTY...WESTERN AND CENTRAL PIMA
COUNTY AND SOUTHEASTERN PINAL COUNTY) WILL BE ABOVE THE 15 PERCENT
THRESHOLD DUE TO COOLING...BUT PORTIONS OF SOUTHERN GRAHAM...EASTERN
PIMA...SANTA CRUZ AND COCHISE COUNTIES WILL STILL REMAIN DRY ENOUGH
FOR CONCERN. THUS...WILL GO AHEAD AND ISSUE A FIRE WEATHER WATCH FOR
ZONE 148 FOR WEDNESDAY AS WELL.

&&

.AVIATION...HIGH CLOUDS WILL CONTINUE TO MOVE INTO THE DESERT
SOUTHWEST FROM THE WEST THIS EARLY MORNING. WINDS WILL BE LIGHT AND
TERRAIN DRIVEN FOR THE START OF THE DAY...HOWEVER...A STRONG STORM
SYSTEM MOVING SOUTH INTO THE WESTERN GREAT BASIN TODAY WILL BRING
STRONG AND GUSTY SOUTH TO SOUTHWEST WINDS THIS AFTERNOON. WIND
SPEEDS BETWEEN 15 AND 25 KTS WITH GUSTS TO 40 KTS ARE EXPECTED BY
AFTERNOON AND WILL CONTINUE INTO THE EARLY EVENING HOURS. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS

&&

.TWC WATCHES/WARNINGS/ADVISORIES...FIRE WEATHER RED FLAG WARNING 1PM
     TO 7PM MST TODAY FOR ZONES 147...148 AND SRN 146 BELOW 6000
     FEET.
