.SYNOPSIS...Warm and dry conditions will continue into the upcoming
weekend, with high temperature 4 to 8 degrees above normal. Strong
and gusty easterly winds are expected Wednesday and Thursday.

&&

.DISCUSSION...The models are in good agreement through Thursday,
as high pressure aloft builds across central California today,
moving east across the Great Basin through Thursday. This will
result in continued dry conditions, with high temperatures warming
to 4-8 degrees above normal. On Wednesday and Thursday, strong
surface high pressure builds down the front range of the Rockies
into west Texas, resulting in strong and gusty easterly winds across
southeast Arizona. Sustained wind speeds of 20-25 mph and gusts to
35-45 mph are expected in locations exposed to easterly winds.
Forecasted wind speeds continue to remain below advisory criteria.
High temperatures will cool 2-4 degrees across eastern areas on
Wednesday as the east winds begin to kick in, with highs lowering an
additional 3-5 degrees areawide on Thursday.

Late Thursday into Saturday, the models continue to show a cut off
low moving into the Baja Peninsula. Although model solutions diverge
in regards to the amount of mid-level moisture this feature spreads
across the forecast area, any precipitation looks to be very light.
Our current forecast reflects PoPs of 10 percent or less. High
temperatures continue to be 4-8 degrees above normal, with Thursday
being the `coolest` day.

Sunday into the middle of next week, the models point to a more
progressive pattern developing across the western United States. The
models differ on the exact evolution of this pattern and track of
the synoptic scale features, which is expected this far out. Outside
of cooler temperatures over this period, the exact timing of the
precipitation chances remain uncertain until the models come into
better consensus. Right now, the forecast for Sunday afternoon
through Tuesday reflects a slight chance/chance of precipitation
(PoPs of 15-30 percent) across mainly the eastern half of the
forecast area.

25 mph and gusts to 35-45 mph in locations exposed to east winds.
Min RH levels at all elevation will be in the 12-22 percent range
