AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PHOENIX AZ
325 PM MST MON APR 13 2009

.SYNOPSIS...
A PACIFIC LOW PRESSURE SYSTEM WILL BRING STRONG GUSTY WINDS FROM THE
SOUTHWEST AND WEST TUESDAY AFTERNOON THROUGH WEDNESDAY WITH BLOWING
SAND AND DUST IN THE DESERT AREAS. THE SPRING ROLLER COASTER RIDE
WILL CONTINUE AS MUCH COOLER AIR BEHIND A COLD FRONT CAUSES HIGH
TEMPERATURES TO TAKE A SUDDEN DROP BACK DOWN 15 TO 20 DEGREES
WEDNESDAY COMPARED WITH TUESDAYS HIGHS. LIMITED MOISTURE WITH THIS
SYSTEM WILL BRING A SLIGHT CHANCE OF SHOWERS TO SOUTH-CENTRAL ARIZONA
MOSTLY NORTH AND EAST OF PHOENIX TUESDAY NIGHT AND WEDNESDAY INTO
WEDNESDAY NIGHT. HIGH PRESSURE ALOFT FROM THE PACIFIC WILL CAUSE
TEMPERATURES TO RISE BACK UP AGAIN FRIDAY AND THE WEEKEND.

&&

.DISCUSSION...
UNDER SUNNY SKIES...TEMPERATURES WERE GENERALLY 9 TO 12 DEGREES
WARMER IN SOUTH-CENTRAL ARIZONA INCLUDING THE GREATER PHOENIX AREA
AND 5 TO 9 DEGREES WARMER IN SOUTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA EARLY THIS AFTERNOON COMPARED WITH THE SAME TIME
YESTERDAY. WIND WAS VARIABLE WITH SUSTAINED SPEEDS MOSTLY LESS THAN
10 MPH.

THE SOUTHERN PORTION OF AN AXIS OR RIDGE OF HIGH PRESSURE ALOFT WAS
MOVING EAST ACROSS OUR AREA AND WAS RESPONSIBLE FOR THE MUCH WARMER
WEATHER TODAY.

A VERY WEAK LOW PRESSURE SYSTEM WAS LOCATED WEST OF NORTHERN BAJA
CALIFORNIA NEAR 128 DEGREES WEST LONGITUDE THIS AFTERNOON AND MOVING
EAST. AS THE HIGH PRESSURE SYSTEM MOVES EAST OF OUR AREA...HIGH
CLOUDINESS AHEAD OF THE VERY WEAK LOW PRESSURE SYSTEM WILL INCREASE
FROM THE WEST ACROSS OUR AREA AND BECOME THICKER TONIGHT WITH WARMER
TEMPERATURES.

A STRONG LOW PRESSURE SYSTEM WAS MOVING SOUTHEAST NEAR THE FAR
NORTHWEST WASHINGTON STATE COAST THIS AFTERNOON. THIS SYSTEM WILL
MOVE SOUTHEAST OVER THE WESTERN UNITED STATES TUESDAY AND WEDNESDAY.
THE STRONG SOUTHERN PORTION OF A COLD FRONT ASSOCIATED WITH THIS
SYSTEM IS EXPECTED TO SWEEP EAST INTO SOUTHEAST CALIFORNIA TUESDAY
AFTERNOON AND ACROSS SOUTHWEST AND SOUTH-CENTRAL ARIZONA TUESDAY
NIGHT. AS A RESULT...STRONG GUSTY WINDS FROM THE SOUTHWEST AND WEST
ARE EXPECTED ACROSS OUR AREA TUESDAY AFTERNOON THROUGH WEDNESDAY WITH
BLOWING SAND AND DUST IN THE DESERT AREAS. A HAZARDOUS WEATHER
OUTLOOK HAS BEEN ISSUED FOR THIS.

A WIND ADVISORY HAS BEEN ISSUED FOR SOUTHEAST CALIFORNIA AND
