NORTHERN ARIZONA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
230 PM MST FRI SEP 06 2002
.SYNOPSIS...TROPICAL MOISTURE CONTINUES TO STREAM NORTHWARD OVER
ARIZONA IN ADVANCE OF A STRONG EASTERN PACIFIC TROUGH OF LOW
PRESSURE. EXPECT MOSTLY CLOUDY SKIES WITH NUMEROUS HEAVY SHOWERS AND
THUNDERSTORMS TONIGHT AND SATURDAY...CONTINUING INTO MONDAY.
.DISCUSSION...THE EASTERN PACIFIC TROUGH CONTINUES TO APPROACH THE
WEST COAST. THIS HAS LED TO A TIGHTENING OF THE GRADIENT BETWEEN
THIS SYSTEM AND THE SUBTROPICAL HIGH OVER NORTHERN MEXICO. TROPICAL
MOISTURE CONTINUES TO STREAM NORTHWARD OVER ARIZONA THIS AFTERNOON
IN THE CONFLUENCE REGION BETWEEN THESE TWO SYSTEMS. THERE HAS BEEN A
PERSISTENT BAND OF SHOWERS AND THUNDERSTORMS IN THIS AREA MOST OF
THE DAY TODAY. TO THE EAST...NUMEROUS SHOWERS AND THUNDERSTORMS HAVE
DEVELOPED OVER THE HIGHER TERRAIN AND ARE MOVING TO THE NORTHEAST.
EXPECT AREAL COVERAGE TO CONTINUE TO INCREASE DURING THE AFTERNOON
AND TONIGHT. MAV MOS HAS SOME OF THE HIGHEST POP NUMBERS SEEN ALL
SUMMER...AND BOTH THE AVN AND ETA SHOW SIGNIFICANT PRECIPITATION
AMOUNTS THROUGH SUNDAY...SO WILL GO WITH SOME STRONG WORDING IN THE
ZONE FORECAST PACKAGE. IF SUFFICIENT RAIN FALLS OVERNIGHT WE MAY
NEED TO ISSUE A FFA FOR PORTIONS OF THE CWFA TOMORROW. THIS WILL
NEED TO BE CONSIDERED BY THE MIDNIGHT SHIFT. WET WEATHER SHOULD
CONTINUE INTO MONDAY WITH ONLY SLIGHT DECREASES IN POPS.
.EXTENDED...DRYING TREND THAT WAS SEEN IN PREVIOUS MODEL RUNS IS NO
LONGER THERE. WITH SUFFICIENT RESIDUAL LOW LEVEL MOISTURE WOULD
EXPECT SCATTERED SHOWERS EACH DAY...ESPECIALLY OVER THE HIGHER
TERRAIN. TEMPS NEAR SEASONABLE FOR THE ENTIRE EXTENDED PERIOD. DB
.FGZ...NONE.
