.KEY MESSAGES...

* Strong upper ridging will build into the Western U.S. into early
  next. This will result in a rapid increase in temperatures,
  especially this weekend into next week.

&&

.DISCUSSION...
Shortwave trough that brought some unsettled weather and cooler
temperatures to the region has shifted east as high pressure begins
to build in from the west. There is still one piece of energy
trailing this exiting shortwave located over the Rocky Mountain
states that will bring some enhanced northerly winds to portions of
northern Mohave, Lincoln, and northeast Clark counties this
afternoon and evening, but overall winds will be trending lighter
across the area.

High pressure will build over the region into next week with rapidly
rising temperatures and dry conditions. Highs today will generally
be about 10 degrees warmer than Tuesday with temperatures increasing
through the weekend before likely peaking Monday and Tuesday with
temperatures some 10-20 degrees above normal for mid-May. In fact,
many areas may see their first triple- digit temperatures this year
as we enter the workweek with Las Vegas sitting at a 40% chance on
Sunday, rising to 90% by Monday and Tuesday. Moderate to Major Heat
Risk also looks to increase in coverage, especially across Death
Valley and the Colorado River Valley. As confidence increases we may
need Extreme Heat Watches and/or Warnings.

.AVIATION...For Harry Reid...For the 12Z Forecast
Package...For most of the time today and tonight, winds will follow
typical directional patterns and remain under 8KT. The exception is
this evening between 03Z-06Z when there is a low chance for
northeast winds to 10KT to push into the valley. If this did occur,
winds would switch back to the typical light southwest by 09Z. VFR
clouds this morning over 15kft will clear with mostly clear skies
expected through the period.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Typical wind patterns
below 10KT are generally expected across the region today and
tonight. KBIH into the Owens Valley will see north winds around 10KT
occasionally gusting 15-20KT this afternoon which will wane after
sunset. Low chance for a push of west wind at KBIH this evening
around 00Z, but by 03Z typical north to northwest winds below 10KT
will return. Skies will be mostly clear through the period.
