.KEY MESSAGES...

* Mild conditions will continue across the region through the
  upcoming week.

* A disturbance will bring a 15-30% chance for precipitation to
  portions of Inyo and Esmeralda counties late week.

.DISCUSSION...through Sunday.

A ridge over the southwestern United States maintains warm and dry
conditions for most of the area through the end of the week. High
temperatures will be 10 to 15 degrees above average for this time of
year at most locations. Daily temperature records will be in
jeopardy for many regional climate sites - see the CLIMATE section
below for more details. Meanwhile, low sun angles and light surface
winds promote inversions in certain narrow valleys including Death
Valley, which means temperatures will stay relatively cool for those
locations through at least midweek.

Zonal flow develops aloft later this week as a system moves into the
Pacific Northwest and the ridge over the southwest deamplifies. This
pattern allows for improved moisture advection and increasing
precipitation chances this weekend, mostly in Inyo and Esmeralda
counties. The rest of the forecast area should remain dry with an
increase in high clouds.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...Winds
remain light and follow typical, daily patterns throughout the TAF
period. FEW mid and high clouds will filter through the area as
well.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Winds follow typical
daily directional patterns with speeds of less than 10 knots.
Northerly gusts in the Colorado River Valley will decrease after
sunset, but remain elevated at KIFP. These winds should increase
again tomorrow afternoon, but not be as strong as today. VFR
conditions are expected with periods of mid and high clouds.

temperature and/or forecast warm low temperature within 3 degrees of
