AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
930 AM MST FRI JUL 23 2004

.SYNOPSIS...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
DEVELOP EACH DAY INTO EARLY NEXT WEEK. THE BEST CHANCE FOR STORMS
THE NEXT FEW DAYS WILL BE ACROSS THE MOGOLLON RIM AND WHITE
MOUNTAINS AREAS. TEMPERATURES WILL REMAIN NEAR SEASONABLE LEVELS.
&&

.DISCUSSION...MID LEVEL RIDGE AXIS LOCATED JUST SOUTH OF THE
FLAGSTAFF AREA THIS MORNING. THIS IS RESULTING IN A SOUTHWESTERLY
FLOW OVER THE AREA NORTH OF FLAGSTAFF WITH SOME EASTERLY FLOW TO OUR
SOUTH. LOW LEVEL MOISTURE IS HIGHEST OVER SOUTHERN ARIZONA WITH
ANOTHER AREA OF HIGHER DEWPOINTS OVER WESTERN NEW MEXICO. AFTERNOON
UPSLOPE FLOW OVER YAVAPAI COUNTY MAY DRAW BETTER MOISTURE INTO THAT
AREA. ALSO...SOUTHEASTERLY SURFACE WINDS WILL DEVELOP OVER EAST
CENTRAL AND NORTHEAST ARIZONA AS AN AREA OF COOL SURFACE HIGH
PRESSURE MOVING DOWN THE FRONT RANGE SLIDES INTO THE AREA. THIS
SHOULD PUSH HIGHER DEWPOINTS INTO EXTREME EASTERN PORTIONS OF THE
CWA TODAY. UPPER JET WILL ALSO BE ALIGNED OVER THE NE PART OF THE
STATE TODAY...LENDING SUPPORT TO STORMS THERE. FOR THESE
REASONS...WILL UPDATE THE FORECAST TO INCREASE POPS OVER EASTERN
SECTIONS THROUGH THIS EVENING. SATURDAY THROUGH MONDAY...UPPER HIGH
FORECAST TO MOVE WESTWARD PUTTING OUR AREA IN A GENERAL NORTH TO
NORTHEAST FLOW ALOFT. POPS WILL BE BELOW AVERAGE FOR THIS TIME OF YEAR
ALONG AND NORTH OF THE MOGOLLON RIM. HOWEVER...ANY STORMS THAT
DEVELOP OVER THE RIM WILL PUSH SOUTHWARD INTO YAVAPAI AND NRN GILA
COUNTIES WHERE BETTER LOW LEVEL MOISTURE WILL BE LOCATED. THE RIDGE
IS FORECAST TO MOVE SOUTH TOWARD THE MIDDLE OF NEXT WEEK WHICH WOULD
PUT NORTHERN AZ IN A DRIER PATTERN.

.FGZ WATCHES/WARNINGS/ADVISORIES...NONE.
