.DISCUSSION...
Very dry conditions under increasing high pressure will bring 
well above normal temperatures the next few days. Minimum 
humidities into the 10-15 percent range are expected each day 
with fair overnight recoveries. 
The high pressure system across the southern Rockies will also 
produce breezy to windy conditions today. The strongest winds are 
expected in the gaps and channels of the higher terrain east of 
Phoenix where gusts could reach 35 to 40 mph through early this 
afternoon. Critical fire weather thresholds may be reached early 
this afternoon in a few spots, though winds will generally subside
as conditions dry out. 
Note...Additional Fire Weather Forecast information can be found
in the Area Forecast Discussion. See product PHXAFDPSR.
