.DISCUSSION...Today through Next Wednesday

Hot temperatures remain across the region as high pressure
continues through today. The Extreme Heat Warning out for much of
the area will continue through tomorrow with temperatures about
5-10 degrees above normal. These high temps coupled with little
relief at night make the heat much more dangerous and has
contributed to major HeatRisk aross the lower elevations of the
Mojave Desert.

As the ridge of high pressure breaks down a bit on Thursday
afternoon, a shortwave will move into the area. This will bring
increased winds, causing dangerous fire weather conditions. A Red
Flag Warning is in effect for Thursday and Friday for much of
southern Nevada and Mohave County. Dangerous fire weather
conditions will continue through Saturday over a smaller area.

As the Pacific trough moves in over the weekend, winds will
decrease on Sunday and much cooler temperatures will bring some
well needed relief from the extreme heat. Below normal
temperatures will make a brief appearance Sunday and Monday before
they return to near normal by Tuesday across the area.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...
winds will be light and northeasterly through early afternoon though
intermittent higher gusts will be possible during peak heating, with
winds favoring a southeasterly direction through early evening when
diurnal winds resume. Temperatures today will exceed 100F between
19Z-05Z, peaking at 109F around 23Z-01Z. VFR conditions with clear
skies prevail.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...VFR conditions and clear
skies will continue through Thursday. Winds will largely follow
typical diurnal patterns, and while speeds are expected to be 10KT
or less across the area, intermittent thermally-induced gusts are
possible this afternoon during peak heating. The exception will be
across the Western Mojave Desert, where westerly winds become light
and variable this afternoon, returning to the west and increasing to
12-15KT after sunset. Winds will increase from the south on Thursday
during the late morning hours.

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