.DISCUSSION...
THE PACIFIC TROUGH REMAINS POSITIONED TO OUR WEST OFF THE
SOUTHERN CA COAST AND HAS BEEN REINFORCED BY UPSTREAM ENERGY THIS
MORNING. A WEAK DISTURBANCE AHEAD OF THE TROUGH APPEARS TO BE
GENERATING ENOUGH LIFT IN OUR SATURATED ENVIRONMENT TO CONTINUE
SHOWER ACTIVITY ACROSS NORTH CENTRAL ARIZONA WHERE SCATTERED LIGHT
PRECIPITATION HAS FALLEN WITH SOME LIGHT SNOW AROUND THE FLAGSTAFF
AREA. EXPECT THIS ACTIVITY TO CONTINUE THIS MORNING FAVORING
SOUTHERN COCONINO AND YAVAPAI COUNTIES. A SHORTWAVE APPROACHING
FROM UTAH BY THIS AFTERNOON ENHANCES INSTABILITY AND WILL LIKELY
BRING AN INCREASE IN SHOWER COVERAGE AND INTENSITY. SHOWERS
SHOULD CONTINUE THIS EVENING AND TONIGHT AS THE WAVE PUSHES A FAST
MOVING COLD FRONT SOUTH ACROSS THE AREA THROUGH WEDNESDAY MORNING.

THE BOTTOM LINE IS THAT PRECIPITATION HAS NOT ENDED FOR NORTHERN
ARIZONA AND SHOWERS WILL CONTINUE TO AFFECT THE AREA TODAY THROUGH
WEDNESDAY MORNING. PRECIPITATION AMOUNTS WILL GENERALLY BE LIGHT
AND SPOTTY WITH UP TO 1 TO 3 ADDITIONAL INCHES OF SNOWFALL
POSSIBLE IN HIGHER TERRAIN AREAS. SNOW LEVELS WILL GENERALLY HOVER
FROM 4500-5500 FEET...SLIGHTLY HIGHER TOWARDS THE WHITE MOUNTAINS.

COOL TEMPERATURES WILL CONTINUE TODAY AND WEDNESDAY BEFORE WARMING
UP THURSDAY INTO THE WEEKEND. HIGH PRESSURE RETURNS TO THE WEST
COAST THROUGH THE WEEKEND WITH NO SIGN OF ADDITIONAL PRECIPITATION
THROUGH AT LEAST MONDAY OF NEXT WEEK.

.AVIATION...
FOR THE 12Z PACKAGE...AREAS OF MAINLY MVFR CIGS THIS MORNING...WITH

COVERAGE THROUGH 18Z THEN INCREASING COVERAGE AS A WEATHER

CONDITIONS WITH THE STRONGER CELLS. AVIATION DISCUSSION NOT UPDATED
