.SYNOPSIS...For today, steady northwest winds and cooler
temperatures than yesterday north of the Mogollon Rim. Similar
temperatures and lighter winds tomorrow. By Tuesday onward,
unprecedented heat takes over with temperatures more typical of
summer. Take the appropriate precautions if you are planning on
any outdoor activity through the week.

.DISCUSSION...A departing shortwave trough coupled with a strong
east Pacific ridge is reinforcing breezy northwesterly winds
across northern AZ today. Daytime temperatures are 5-15 degrees
cooler than yesterday for sites north of the Mogollon Rim
following a dry cold front that clipped far northeastern AZ. For
tomorrow, expect relatively minimal temperature change from today
with lighter north to northwest winds as the gradient aloft
relaxes slightly.

Starting Tuesday, we enter a period of light winds, mostly clear
skies, and record breaking heat as the anomalous ridge begins to
propagate eastward. Several daily and possibly monthly temperature
records will be broken Tuesday, but the warming doesn`t stop there.
Daytime highs are forecast to reach 20-30 degrees above normal as
the high pressure centers overhead by the end of the week. These are
temperatures that would be more typical of June. Do not be caught
off guard by the unseasonable heat if you are planning on any
outdoor activity over the week.

There is some indication that the ridge will weaken early next
week and temperatures will cool some, but still no strong signal
for precipitation at this time.
