AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
905 PM MST SUN JUN 11 2006

SOUTHWEST AND SOUTH-CENTRAL ARIZONA...AND SOUTHEAST CALIFORNIA
FORECAST DISCUSSION

.SYNOPSIS...
HIGH PRESSURE ALOFT WILL GIVE CLEAR SKIES AND WARMER TEMPERATURES
THROUGH THE MIDDLE OF THE WEEK...WITH HOTTEST SOUTH-CENTRAL DESERTS
EXPECTED TO SURPASS THE 110 DEGREE MARK TUESDAY AND WEDNESDAY. A LOW
PRESSURE SYSTEM OFF THE CALIFORNIA COAST WILL GRADUALLY PUSH INTO
THE GREAT BASIN REGION TUESDAY AND WEDNESDAY. THIS WILL EVENTUALLY
RESULT IN LOWER DAYTIME TEMPERATURES BY THE END OF THE WEEK. IN
ADDITION...AS THE UPPER LOW PUSHES INLAND...WINDS WILL INCREASE
MONDAY AND TUESDAY...ESPECIALLY ACROSS SOUTHEAST CALIFORNIA AND FAR
SOUTHWEST ARIZONA.

&&

.SHORT TERM...
TONIGHT THROUGH WEDNESDAY...
UPPER LOW OFF CA COAST WITH AZ AHEAD OF THE SYSTEM AND UNDER VERY
DRY SWLY FLOW ALOFT. GOES PWAT IMAGERY THIS EVE HAS ALL OF AZ LESS
THAN ONE HALF INCH VALUES...AND SURFACE DEWPOINTS ARE IN THE LOW
TEENS TO MID 20S OVER THE AZ DESERTS...WITH SOMEWHAT HIGHER VALUES
ALONG THE LOWER CO RIVER...WHICH IS UNDER A MODERATE LOW LEVEL SLY
FLOW. CLEAR SKIES...AS SEEN IN IR IMAGERY...AND MOSTLY LIGHT WINDS
WILL PREVAIL REST OF TONIGHT. NO UPDATES NEEDED. REST OF FORECAST IS
FROM THE PREVIOUS DAY SHIFT.

WE ARE STILL ANTICIPATING A SIGNFICANT WARMING TREND THROUGH THE
MIDDLE OF THE WEEK ACROSS THE CWA...WITH THE HOTTEST DAYTIME
READINGS EXPECTED OVER THE LOWER DESERTS OF SCNTRL AZ. THIS WARMING
IS DUE TO BUILDING HEIGHTS/THICKNESSES EXPECTED OVER THE AREA AS
RIDGE PUMPS UP STRONGLY TO OUR E. 500MB HEIGHTS RISE TO NEAR 594 DM
BY TUESDAY AFTN/INTO WED OVER ERN AZ...WITH LOWER VALUES FURTHER W
CLOSER TO AN OFFSHORE UPPER LOW. PHX HEAT WATCH/WARNING SYSTEM
INDICATES THAT WE COULD GET CLOSE TO HEAT ADVISORY CRITERIA FOR
SCNTRL DESERTS TUESDAY. WILL LET MID SHIFT ISSUE THIS PRODUCT IF
NEED BE WITH LATER GUIDANCE IN HAND. CRITERIA NOT EXPECTED TO ME MET
OUT IN WRN CWA WITH LOWER TEMPS ANTICIPATED.

OFFSHORE UPPER LOW WILL MOVE INLAND BY TUESDAY...PROVIDING FOR A
TIGHTENING PRESSURE GRADIENT AND THE POSSIBILITY OF WINDY CONDITIONS
OVER ESPECIALLY WRN CWA MONDAY...BUT ESPECIALLY ON TUESDAY. LESS
WINDS ON TAP FOR WEDNESDAY.

&&

.LONG TERM...
WEDNESDAY NIGHT THROUGH SUNDAY...
LOOK FOR A CONTINUATION OF THE DRY WEATHER ACROSS ENTIRE CWA FOR THE
EXTENDED PERIOD...AS FLOW ALOFT GRADUALLY BECOMES MORE WESTERLY WITH
TIME. THE STRONG UPPER HIGH SHIFTS SOUTH IN RESPONSE TO THE
PROGRESSIVE SHORT WAVE THAT SWEEPS ACROSS ARIZONA. TIMING OF THIS
SYSTEM IS STILL UNCERTAIN...BUT WILL CALL FOR A GENERAL MODERATION
OF TEMPERATURES BY LATE IN THE WEEK. HEIGHTS DO NOT CHANGE
ALL THAT MUCH...AND WILL KEEP HIGH TEMPS WARMER THAN GFS ENSEMBLE
GUIDANCE. LATEST DGEX NOW CALLS FOR A BIGGER HEIGHT RISE BY FRIDAY
AFTERNOON...AND INTO NEXT WEEKEND FOR ANOTHER WARMING TREND.

&&

.FIRE WEATHER...
WINDS WILL BE STRONGER THE NEXT FEW DAYS...PRIMARILY OVER SOUTHEAST
CALIFORNIA AND SOUTHWEST ARIZONA. CRITICAL FIRE WEATHER THRESHOLDS
MAY BE REACHED IN JOSHUA TREE NATIONAL PARK MONDAY. A FIRE WEATHER
WATCH MAY BE NEEDED IN SOUTHEAST CALIFORNIA FOR TUESDAY AS SIMILAR
CONDITIONS ARE APT TO LAST LONGER. WINDS ARE NOT EXPECTED TO BE
QUITE AS STRONG IN ARIZONA...ESPECIALLY IN SOUTH-CENTRAL ARIZONA.
ON WEDNESDAY...BREEZY TO WINDY CONDITIONS ARE ANTICIPATED BUT
CONDITIONS ARE EXPECTED TO REMAIN BELOW CRITICAL FIRE WEATHER
THRESHOLDS.
