IS AROUND 20 TO 40 PERCENT OVER THE MOUNTAINS, CLOSER TO 15 TO
25 PERCENT WEST OF THE MOUNTAINS.
..DISCUSSION FROM PHXFWFPSR
ABOVE NORMAL TEMPERATURES TODAY WILL BE FOLLOWED BY A SIGNIFICANT
COOLDOWN TO BELOW NORMAL LEVELS DURING THE FIRST PART OF THE WEEK.
EASTERN DISTRICTS WILL LIKELY OBSERVE EASTERLY WIND GUSTS UPWARDS
