.KEY MESSAGES...

* Dry and pleasant weather conditions are expected through the
  weekend, with cool temperatures gradually returning to seasonal
  normals.

&&

.DISCUSSION...through early next week.

Broad troughing will persist today across the region keeping
temperatures well below normal but otherwise dry and pleasant.
High pressure will gradually begin to build in Friday and into
the Weekend which will allow for a warm up trend, with
temperatures returning to near normal levels by Sunday. A modest
enhancement in northerly winds is expected Friday as the trough
axis shifts east with the strongest winds favored along the
Colorado River Valley.

Guidance has trended to favor stronger ridging early next week
across the Southwest, with a fairly strong shortwave dropping
through the PacNW and into the Northern Rockies Monday, mainly
resulting in a slight cooling and enhanced surface winds Monday
and Tuesday in our region. Meanwhile, a fairly deep cut off low
will be meandering off the west coast of Southern California, and
is poised to eject inland by the middle of the week. This may
spread increased cloud cover and some shower activity into the
Mojave Desert by Wednesday and slightly cooler conditions, but
uncertainty remains fairly high this far out.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Clear
skies are expected through the TAF period. Winds today will
remain light and generally less than 10 knots, favoring north to
northeast directions through the afternoon and evening hours.
Winds overnight will shift more to the north-northwest with speeds
of 8-10 knots through daybreak Friday.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Clear skies with
northerly winds are favored for the regional TAF sites. Surface
winds of 5-10 knots will be common outside of the Colorado River
Valley, while stronger winds with gusts of 15-25 knots are more
likely near KIFP and KEED.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
