.KEY MESSAGES...

* Breezy south-southwesterly wind gusts will continue through the
  week with dry conditions and near-normal temperatures.

&&

.DISCUSSION...Through Friday

A trough is deepening over the Pacific Northwest is pushing last
week`s high pressure eastward.  The interaction between these two
systems resulted in an pressure gradient and offered strong winds
for much of Saturday. Winds ease into the late night but rebuild
late Sunday morning. Sunday afternoon will offer another batch of
widespread gusty winds peaking around 30 mph for most areas with some
of the higher elevations and favored gaps and passes exceeding 35
mph. The pressure gradient reduces into the work week, but the
influence of the trough will offer breezy afternoons through much of
the week. Temperatures will be moving closer to average due to this
pattern change, with a gradual cooling trend expected into the the
mid-week. High temperatures will fall back to near average (90s to
low 100s). Low temperatures, however, will only see some slight
reduction, staying around 5 degrees above average. Temperatures look
to gradually increase again by the end of the work week as pressure
begins to increase.
