FORECAST DISCUSSION

.SYNOPSIS...
VERY MOIST TROPICAL AIR WILL CONTINUE WITH A CHANCE OF SHOWERS AND
THUNDERSTORMS...STRONG GUSTY WINDS AND LOCALLY HEAVY RAIN MAINLY IN
SOUTH-CENTRAL ARIZONA INCLUDING THE GREATER PHOENIX AREA THROUGH
THIS EVENING. HIGH PRESSURE ALOFT FROM THE CALIFORNIA COAST WILL
GRADUALLY MOVE EAST...WITH GENERALLY ONLY A SLIGHT CHANCE OF SHOWERS
AND THUNDERSTORMS IN SOUTHWEST AND SOUTH-CENTRAL ARIZONA DURING MID
WEEK. THIS SYSTEM WILL ALSO BRING SOME WARMING. ONCE THE HIGH
PRESSURE SYSTEM REACHES THE 4 CORNERS...THE POSSIBILITY OF SHOWERS
AND THUNDERSTORMS WILL SPREAD BACK ACROSS THE LOWER COLORADO RIVER
VALLEY AND SOUTHEAST CALIFORNIA BY THIS COMING WEEKEND.

&&

.DISCUSSION...
SHOWERS AND THUNDERSTORMS DEVELOPED ACROSS SOUTH-CENTRAL ARIZONA
TODAY MAINLY OVER THE HIGHER TERRAIN AND AREAS NEAR THE HIGHER
TERRAIN. NATIONAL WEATHER SERVICE RADAR INDICATED SEVERE STORMS WITH
STRONG GUSTY DAMAGING WINDS AND FLASH FLOODING IN FAR NORTHEAST
MARICOPA COUNTY AND SOUTHERN GILA COUNTY IN THE SALT RIVER LAKES
RECREATIONAL AREA PUNKIN CENTER. THESE SHOWERS AND THUNDERSTORMS
WERE ASSOCIATED WITH THE SOUTHERN END OF A WEAK LOW PRESSURE SYSTEM
MOVING EAST IN A MOIST AND UNSTABLE AIRMASS ACROSS THE AREA. THERE
WERE ALSO ISOLATED SHOWERS AND THUNDERSTORMS OVER JOSHUA TREE
NATIONAL PARK THIS AFTERNOON. OTHERWISE SKIES WERE MOSTLY SUNNY WITH
SOME CUMULUS CLOUDS ACROSS SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA
TODAY. TEMPERATURES WERE GENERALLY A FEW DEGREES WARMER AND HUMIDITY
WAS SLIGHTLY LOWER.

HIGH PRESSURE ALOFT HAS BEEN TO OUR EAST AND TO OUR WEST OFF THE
CALIFORNIA COAST. THE HIGH PRESSURE SYSTEM OFF THE CALIFORNIA COAST
WILL MOVE SLOWLY EAST...REACHING THE 4 CORNERS BY THE END OF THE
WEEK. AS THIS HAPPENS...SOME RELATIVELY DRIER AIR WILL KEEP SHOWERS
AND THUNDERSTORMS AWAY FROM SOUTHEAST CALIFORNIA AND THE LOWER
COLORADO RIVER VALLEY INCLUDING YUMA TUESDAY THROUGH THURSDAY OR
FRIDAY. THERE WILL ALSO BE ONLY A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS IN THE REMAINDER OF SOUTHWEST ARIZONA...AND
SOUTH-CENTRAL ARIZONA INCLUDING THE GREATER PHOENIX AREA TUESDAY
THROUGH THURSDAY OR FRIDAY. IN ADDITION...THIS SYSTEM WILL BRING
SOME WARMING TO THE ENTIRE AREA.

ONCE THE HIGH PRESSURE SYSTEM REACHES THE 4 CORNERS...THE
POSSIBILITY OF SHOWERS AND THUNDERSTORMS WILL SPREAD BACK ACROSS THE
LOWER COLORADO RIVER VALLEY AND SOUTHEAST CALIFORNIA BY THIS COMING
WEEKEND.

.AVIATION...
DISCUSSION FOR THE 0000 GMT TAFS. SCATTERED THUNDERSTORMS OVER THE
HIGHER TERRAIN NEAR THE PHOENIX METROPOLITAN AREA WILL QUITE LIKELY
PRODUCE GUSTY WIND OUTFLOWS OF 20 TO 25 KNOTS BEFORE 0100 GMT.
ADDITIONAL STORM DEVELOPMENT CLOSER TO THE TAF SITES WILL BE SPOTTY
BUT COULD STILL DIRECTLY AFFECT KPHX AND KIWA WITH BRIEF HEAVY RAIN
AND WIND GUSTS TO 35 KNOTS BETWEEN 0000 AND 0300 GMT. KIPL MAY
EXPERIENCE A MODEST WIND OUTFLOW FROM STORMS OVER THE SAN DIEGO
