NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
900 AM MST FRI AUG 15 2003
.SYNOPSIS...A STRONG WEATHER DISTURBANCE WILL CONTINUE TO BRING
WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY TO THE REGION THROUGH AT
LEAST SATURDAY. MOSTLY CLOUDY CONDITIONS AND FREQUENT SHOWERS WILL
KEEP TEMPERATURES BELOW NORMAL FOR THE NEXT FEW DAYS.
.DISCUSSION...UPPER TROUGH WAS CENTERED OVER SOUTHWEST NEW MEXICO
THIS MORNING. THE TROUGH WILL MOVE SLOWLY TO THE NORTHWEST DURING
THE DAY KEEPING MUCH OF NORTHERN ARIZONA UNDER A NORTHEAST FLOW. THE
AIR MASS WAS RAIN COOLED AND SOMEWHAT STABLE THIS MORNING.
HOWEVER...LOOKS LIKE THERE WILL BE PLENTY OF DAYTIME HEATING FOR
ANOTHER ROUND OF THUNDERSTORMS BUT DOUBTFUL IT WILL BECOME NEARLY AS
UNSTABLE AS THURSDAY AFTERNOON. IN ADDITION...SOME DRY AIR IS
ADVECTING IN FROM COLORADO AND NEW MEXICO SO THIS SHOULD PUT SOME
LIMIT ON ACTIVITY FROM THE MOGOLLON RIM NORTHWARD. ALONG...SOUTH AND
WEST OF THE MOGOLLON RIM DEEPER MOISTURE WILL REMAIN AND STORMS THAT
FORM ON THE RIM WILL MOVE SOUTHWEST INTO THIS DEEPER MOISTURE. AS A
RESULT...A FLASH FLOOD WATCH IS IN EFFECT UNTIL MIDNIGHT TONIGHT FOR
PORTIONS OF YAVAPAI...GILA AND COCONINO COUNTIES. FOR SATURDAY AND
SUNDAY THE UPPER LOW PARKS RIGHT OVER ARIZONA WITH A
DEEP...MOIST...COOL AIR MASS. EXPECT ROUNDS OF ISOLATED TO SCATTERED
THUNDERSTORMS EACH DAY WITH A MORE NORMAL DIURNAL TREND IN
PRECIPITATION.
