AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
935 AM MST FRI APR 24 2009

.SYNOPSIS...A SERIES OF DRY PACIFIC LOW PRESSURE SYSTEMS WILL MOVE
ACROSS THE GREAT BASIN DURING THE NEXT SEVERAL DAYS. DAYTIME
TEMPERATURES WILL DECREASE A FEW DEGREES EACH DAY INTO THE WEEKEND.
SOME AFTERNOON AND EARLY EVENING BREEZES ARE EXPECTED TODAY AND THIS
WEEKEND AS WELL.

&&

.DISCUSSION...FORECAST STILL ON TRACK FOR TODAY AS A LOW PRESSURE
SYSTEM CONTINUED TO APPROACH THE GREAT BASIN REGION. EXPECT SOME
INCREASE IN WIND THIS AFTERNOON WITH EVEN STRONGER WINDS SATURDAY.
SHOULD ALSO SEE MORE CLOUDS SPREADING INTO THE AREA AS THE SYSTEM
MOVES CLOSER. PLEASE REFER TO THE FIRE WEATHER AND PREV DISCUSSION
SECTIONS BELOW FOR MORE DETAILS.

&&

.FIRE WEATHER...WIND AND LOW AFTERNOON HUMIDITY VALUES WILL BE MAIN
FOCUS FOR TODAY INTO EARLY NEXT WEEK AS A COUPLE OF DRY PACIFIC LOW
PRESSURE SYSTEMS IMPACT THE REGION. THE CONFIDENCE IS FAIRLY HIGH
FOR BREEZY TO WINDY CONDITIONS SATURDAY...AND THE LATEST GUIDANCE
SUGGESTED MINIMUM RELATIVE HUMIDITY VALUES COULD APPROACH RED FLAG
THRESHOLDS. AS A RESULT...A FIRE WEATHER WATCH FOR CRITICAL FIRE
WEATHER CONDITIONS WAS ISSUED FOR SATURDAY MORNING INTO EARLY
SATURDAY EVENING FOR FWX ZONE 148. THIS INCLUDES EASTERN PIMA...
SANTA CRUZ...COCHISE...AND SOUTHERN GRAHAM/SOUTHERN GREENLEE
COUNTIES. THE NEXT SYSTEM COULD BRING STRONG WINDS AGAIN AROUND
TUESDAY INTO WEDNESDAY OF NEXT WEEK. OTHERWISE...A BROAD AREA OF LOW
PRESSURE OVER THE WESTERN ONE-HALF OF THE UNITED STATES WILL RESULT
IN COOLER DAYTIME TEMPERATURES AND ELEVATED AFTERNOON AND EARLY
EVENING WIND SPEEDS.

&&

.AVIATION...EXPECT INCREASING CLOUDS THIS MORNING...WITH SCATTERED
CLOUD BASES AT OR ABOVE 15K FT AGL. SURFACE WINDS THROUGH 16Z MAINLY
LESS THAN 10 KTS THEN SWLY 12-23 KTS WITH GUSTS TO NEAR 30 KTS AFTER
16Z TODAY AND CONTINUING IN THE AFTERNOON. AVIATION DISCUSSION NOT
UPDATED FOR TAF AMENDMENTS.

&&

.PREV DISCUSSION...WATER VAPOR IMAGERY SHOWS A BATCH OF CIRRUS
HEADED TOWARD BAJA AND THE DESERT SOUTHWEST AS WELL. MEANWHILE...A
TROUGH THAT IS CURRENTLY MOVING INTO NRN CALIFORNIA WILL DEVELOP
INTO A CLOSED LOW OVER CENTRAL CALIFORNIA AND WESTERN NEVADA BY
EARLY SATURDAY MORNING. THIS SYSTEM WILL HAVE VERY LITTLE MOISTURE
ASSOCIATED WITH IT. HOWEVER...IT WILL BE ACCOMPANIED BY STRONG WINDS
ON SATURDAY. WITH VERY DRY CONDITIONS IN PLACE A FIRE WEATHER WATCH
WAS ISSUED FOR FIRE WEATHER ZONE 148 ON SATURDAY. MORE DETAILS
REGARDING THIS IN THE FIRE WEATHER SECTION BELOW.

THIS SYSTEM WILL SWING THROUGH TO THE EAST ON SUNDAY WITH COOLER
TEMPERATURES EXPECTED DURING THE DAY ON SUNDAY. ANOTHER SYSTEM WILL
DEVELOP OVER THE PAC NW LATE MONDAY/EARLY TUESDAY...WHICH WILL BRING
AN INCREASE IN WINDS AGAIN ON TUESDAY AFTERNOON AND EVENING. THIS
LOW WILL MOVE INTO THE GREAT BASIN ON WEDNESDAY WITH TROUGHINESS
REMAINING TO THE NORTH OF ARIZONA THROUGH THE FORECAST PERIOD. THESE
SYSTEMS WILL NOT HAVE ENOUGH MOISTURE WITH THEM TO WARRANT ANY POPS.
I INHERITED SINGLE DIGIT POPS IN THE GRIDS...BUT THESE VALUES WILL
NOT BE ENOUGH TO MENTION IN THE ZONES.

HIGH TEMPS WILL GENERALLY BE 2 TO 4 DEGS ABOVE NORMAL FOR TODAY AND
SATURDAY...THEN 3 TO 5 DEGS BELOW NORMAL FOR SUNDAY. THEREAFTER...
HIGHS WILL BE AT OR SLIGHTLY ABOVE NORMAL THROUGH THURSDAY. LOWS
WILL BE 8 TO 10 DEGS ABOVE NORMAL FOR SATURDAY MORNING...THEN 2 TO 4
DEGS ABOVE NORMAL FOR THE REMAINDER OF THE FORECAST PERIOD.
