.DISCUSSION...Southeast Arizona will return to a more quiet
weather regime with clear skies and below normal afternoon
high temperatures expected across the majority of the area
today. A building ridge of high pressure over the Desert
Southwest will warm temperatures west of Tucson this weekend.
However, a dry backdoor front will move into the area from the
east, keep afternoon reading below normal east of Tucson into
early next week. This front will result in breezy to locally
windy east to southeast winds Friday into Monday of next week.
Minimum RH values 35-45 percent in valley locations and 50-75
percent in the mountains today, generally lowering to 15-25
percent the second half of next week as drier air moves into
the region. 20-foot winds will be less than 15 mph today,with
gusty east to southeast winds Friday through early next week.
