.SYNOPSIS...High pressure will continue to strengthen over Arizona
through this holiday weekend. Daytime temperatures will warm
enough today through Saturday to challenge long-standing high
temperature records. Cooler and breezy conditions are expected

and near-record high temps will continue to be 15-20 degrees above
normal values through Sunday. Winds look to be light during this
period as well.

From Monday into early Tuesday, low pressure will move eastward
across the region. This will lead to much cooler temps and a
slight chance of showers, mainly along the UT/AZ border. Gusty
southwest winds ahead of the front Monday should become north to
northeast Monday night into Tuesday.


.AVIATION...For the 00Z package...Expect VFR conditions under
mostly clear skies and light winds. Aviation discussion not

high pressure remains over the southwest. Expect daytime highs of 15
to 20 degrees above average. Wind speeds will generally remain light.

increasing southwest wind speeds. As the trough moves through the
region Monday and Monday night, it will push a mostly dry cold front
through northern Arizona, along with a slight chance of showers.
Expect breezy conditions Monday into Tuesday with the frontal
