NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
230 PM MST THU JUN 21 2001

SYNOPSIS...HIGH PRESSURE WILL REMAIN OVER THE REGION FOR THE NEXT
SEVERAL DAYS. INCREASING MOISTURE WILL BRING A CHANCE OF AFTERNOON
SHOWERS AND THUNDERSTORMS MAINLY TO AREAS ALONG AND SOUTH OF THE
MOGOLLON RIM AND WHITE MOUNTAINS INTO NEXT WEEK. EXPECT TEMPERATURES
TO AT OR NEAR NORMAL LEVELS.

DISCUSSION...CONVECTION ONCE AGAIN FIRING OVER THE HIGHER TERRAIN OF
CENTRAL AND SOUTHEAST ARIZONA. AS EXPECTED...CONVECTION HAS FORMED
FARTHER WEST AND NORTH AS COMPARED TO WEDNESDAY. MAIN AREAS ARE OVER
THE WHITE MOUNTAINS AND THE WESTERN MOGOLLON RIM. DUE TO THE
CIRCULATION OVER THE STATE...THE STORMS OVER THE EAST-CENTRAL
MOUNTAINS WILL DROP OFF THE RIM AND INTO THE DESERTS. THE STORMS TO
THE WEST ARE SLOW MOVERS...OR DRIFTING TO THE NORTH. EXPECT MORE
OUTFLOWS THIS AFTERNOON AND EVENING...ALONG WITH GENERAL MOISTURE
TRANSPORT FROM THE MID-LEVEL CIRCULATION. THIS PATTERN WILL CONTINUE
FOR AT LEAST TWO OR THREE MORE DAYS...SO THE FORECAST WILL FOLLOW
THE SAME ROUTE.

BY THE END OF THE WEEKEND AND INTO NEXT WEEK...EXTENDED MODELS ARE
STILL SHOWING INCREASED SOUTHWEST FLOW AND SOME TROUGHING MOVING
INTO THE GREAT BASIN. WILL LEAVE A CHANCE OVER THE RIM AND WHITE
MOUNTAIN ZONES THROUGH THE EXTENDED. OTHER ZONES WILL PROBABLY FALL
INTO SLIGHT CHANCE CATEGORIES...SO WILL JUST WORD AS PARTLY CLOUDY
FOR NOW. WEAK TROUGH LATE IN THE EXTENDED MAY ACTUALLY SERVE TO DRAW
UP DEEPER MOISTURE FROM THE SOUTH BEFORE DRYING US OUT...SO FEEL
THAT MENTIONING PRECIPITATION ALL THE WAY THROUGH IS THE BEST WAY TO
GO FOR NOW. PETERSON.*

.FGZ...NONE.
