NORTHERN AND CENTRAL ARIZONA TODAY. ONLY A FEW AREAS WILL SEE ANY
ADDITIONAL SNOW ACCUMULATIONS...MAINLY ABOVE 5500 FEET AND IN
HEAVIER SHOWERS. DRY WEATHER WILL RETURN BY THE WEEKEND. EXPECT

.DISCUSSION...ANOTHER FAST MOVING WEATHER DISTURBANCE WAS ENTERING
ARIZONA FROM THE WEST DURING THE EARLY MORNING. THE CIRCULATION
CENTER OVER THE CALIFORNIA/ARIZONA BORDER WAS APPARENT ON RADAR AND
INFRARED SATELLITE IMAGERY AT 3:00 AM. FOR THE REMAINDER OF THE DAY
THIS SYSTEM WILL TREK EASTWARD ACROSS THE STATE. SHOWERS WILL BE
MOST NUMEROUS ALONG AND SOUTH OF THE MOGOLLON RIM INTO THE WHITE
