AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
945 AM MST TUE AUG 8 2006

.SYNOPSIS...HIGH PRESSURE OVER THE SOUTHERN PLAINS WILL BUILD
WESTWARD...WITH AN EASTERLY TO SOUTHEASTERLY FLOW RETURNING TO
SOUTHEAST ARIZONA. EXPECT A CHANCE OF MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS THROUGH THE WEEK.
&&

.DISCUSSION...UPPER AIR CHARTS THIS MORNING SHOWED UPPER HIGH OVER
NORTHERN NEW MEXICO WITH EAST TO SOUTHEAST FLOW ACROSS SOUTHEAST
ARIZONA. FURTHER WEST THE FLOW IS SOUTH TO SOUTHWEST WITH UPPER LOW
IN SOUTHWEST OREGON. CLOSER LOOK AT WATER VAPOR IMAGERY AND THE
UPPER AIR DATA SHOWS THAT THERE IS A VERY WEAK DISTURBANCE BETWEEN
EL PASO AND MIDLAND MOVING WEST AROUND 15 MPH. 12Z TUCSON SOUNDING
SHOWED BETTER FLOW THAN YESTERDAY WITH EL PASO A SMIDGE STRONGER.
GOES PRECIPITABLE WATER IMAGERY THIS MORNING SHOWED VALUES
APPROACHING 2 INCHES IN THE LOWER DESERTS WHILE A WEDGE OF DRIER
WITH VALUES DOWN NEAR AN INCH IN FAR SOUTHEAST ARIZONA/SOUTHWEST NEW
MEXICO. HOWEVER THIS WEDGE HAS BEEN DECREASING AS HIGH VALUES
ASSOCIATED WITH AFOREMENTIONED DISTURBANCE IS OVER SOUTHERN NEW
MEXICO AND THE TEXAS BIG BEND. SO WHAT DOES THIS ALL MEAN FOR
SOUTHEAST ARIZONA? WELL THE MODELS ARE PAINTING THAT THE LOWER
DESERTS WEST OF TUCSON MAY BE THE FOCUS POINT LATER THIS EVENING
WHERE FLASH FLOODING WILL BE AN ISSUE. THE DRY AIR EAST OF TUCSON
MAY INHIBIT CONVECTION TODAY. THIS PUT TUCSON RIGHT IN THE MIDDLE.
FOR NOW CURRENT FORECAST FOR THIS AFTERNOON LOOKS ON TRACK BUT WILL
LIKELY MAKE SOME CHANGES FOR TONIGHT IN THE AFTERNOON PACKAGE AND
FOCUS ON AREAS IN WESTERN/CENTRAL PIMA COUNTY.
