NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
230 PM MST SAT JUL 14 2001

.SYNOPSIS...EXPECT SHOWER AND THUNDERSTORM ACTIVITY TO PERSIST
THROUGH THE COMING WEEK. A SLIGHT SHIFT IN THE UPPER WIND PATTERNS
WILL RESULT IN A MINOR DECREASE IN SHOWER AND THUNDERSTORM ACTIVITY
OVER THE WEST SUNDAY THROUGH TUESDAY. VERY LITTLE CHANGE IN ACTIVITY
IS EXPECTED FROM FLAGSTAFF EASTWARD. BY WEDNESDAY...MOISTURE LEVELS
WILL BEGIN TO SLOWLY INCREASE...WITH SHOWER AND THUNDERSTORM
ACTIVITY RETURNING TO MUCH OF THE REGION.

.DISCUSSION...STRONG HEATING COMBINED WITH SOME MID TO UPPER LEVEL
FORCING AND A BIT OF SHEAR HAS MADE FOR AN ACTIVE DAY TODAY. EXPECT
THIS FORCING TO END THIS AFTERNOON OR EVENING AS THE SHORTWAVES
RESPONSIBLE MOVE AWAY FROM THE AREA. TROUGH OFF THE WEST COAST WILL
STRENGTHEN A BIT THROUGH AT LEAST MONDAY...PROVIDING SEVERAL DAYS OF
SOUTHWEST FLOW. WILL NOT DRY THINGS OUT AS FAST AS MODELS WOULD
LIKE...BUT WILL SHOW A DRYING TREND NEXT FEW DAYS OVER THE WESTERN
ZONES. BY DAY FOUR...WEST COAST TROUGH WILL RELAX A BIT AND EXPECT
THE MOISTURE BOUNDARY TO MOVE BACK WESTWARD. THE WESTWARD PUSH WILL
NOT BE ANYTHING GREAT...BUT JUST ENOUGH TO MENTION CHANCE POPS AGAIN
IN THE WESTERN ZONES. THE EASTERN ZONES ARE NOT LIKELY TO HAVE A
DRYING TREND AT ALL DURING THIS FORECAST PERIOD. PETERSON.

.FGZ...NONE.
