EAST OF THE TERMINAL THIS EVENING. AN OUTFLOW BOUNDARY MOVED THROUGH
THE TERMINAL FROM THE SOUTHEAST ABOUT AN HOUR AGO AND WILL KEEP
WINDS BLOWING FROM 160 FOR A COUPLE MORE HOURS. AFTERWARD A RETURN
TO SOUTHWESTLY WINDS IS EXPECTED. SATURDAY WILL SEE A SLIGHTLY
HIGHER CHANCE OF A STORM AT THE TERMINAL...WITH HIGHER CHANCES IN
THE MORMON MESA...PEACH SPRINGS...AND DAGGETT CORRIDORS. ANY
