631 AM MST SUN JUL 16 2006

AZZ019-029>035-171445-
NORTHERN GREENLEE COUNTY-SOUTHEAST PINAL COUNTY-
UPPER GILA RIVER VALLEY-WESTERN PIMA COUNTY-TOHONO OODHAM NATION-
TUCSON METRO/MARANA/GREEN VALLEY-SANTA CRUZ COUNTY-COCHISE COUNTY-
631 AM MST SUN JUL 16 2006

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ARIZONA AND SOUTHEAST ARIZONA.

.DAY ONE...TODAY AND TONIGHT.

HIGH PRESSURE IS CURRENTLY CENTERED OVER UTAH WHICH IS A FAVORABLE
POSITION FOR THE CLOCKWISE FLOW AROUND THE HIGH TO PULL MOISTURE
FROM THE EAST. IN ADDITION...A LOW PRESSURE SYSTEM WHICH IS
CURRENTLY MOVING WESTWARD ACROSS NORTHEAST MEXICO IS EXPECTED TO
MOVE TOWARD THE DESERT SOUTHWEST THROUGH THE REMAINDER OF THE
WEEKEND. THIS SYSTEM IS ACCOMPANIED BY ABUNDANT MOISTURE...AND AS
THE SYSTEM MOVES CLOSER TO SOUTHEAST ARIZONA THE UPPER LEVEL
DYNAMICS ASSOCIATED WITH THE SYSTEM WILL HELP TO TRIGGER STRONG TO
POSSIBLY SEVERE STORMS ONCE AGAIN ACROSS SOUTHEAST ARIZONA...MAINLY
DURING THE LATE AFTERNOON AND EVENING HOURS WHEN PEAK DAYTIME
HEATING IS AT ITS BEST. THE STORMS THAT DEVELOP THIS AFTERNOON WILL
INITIALLY FORM OVER THE MOUNTAINS OF THE EASTERN ZONES OF NORTHERN
GREENLEE...GRAHAM AND COCHISE COUNTIES AND WILL PUSH WEST. THE
MAIN THREAT WITH SOME OF THE STORMS THAT DEVELOP THIS AFTERNOON
WILL BE TO PRODUCE DAMAGING DOWN-BURSTS. HOWEVER...LARGE HAIL
CANNOT BE RULED OUT AS A THREAT AS WELL.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

THE UPPER LOW WILL BEGIN TO MOVE ACROSS THE BAJA PENINSULA ON
MONDAY...BUT THE SYSTEM WILL STILL BE CLOSE ENOUGH TO ENHANCE ANY
OF THE STORMS THAT DEVELOP ON MONDAY. A FEW OF THE STORMS COULD
REACH SEVERE LIMITS WITH DAMAGING WINDS THE MAIN THREAT.

ONCE THE UPPER LOW PUSHES WEST LATE MONDAY AND INTO TUESDAY THE
UPPER LEVEL DYNAMICS WILL HAVE MOVED WEST AS WELL. THEREFORE THE
THREAT FOR SEVERE WEATHER WILL DECREASE. HOWEVER...THERE WILL
STILL BE PLENTY OF MOISTURE IN PLACE AND COMBINED WITH THE DAYTIME
HEATING ANY OF THE STORMS THAT DEVELOP MAINLY DURING THE AFTERNOON
AND EVENING HOURS TUESDAY THROUGH SATURDAY COULD BRIEFLY REACH
SEVERE LIMITS...HOWEVER ORGANIZED SEVERE WEATHER IS NOT EXPECTED.
