.KEY MESSAGES...
* A drying trend is expected this week as flow becomes more
  westerly. Relatively cooler temperatures will also overspread the
  region by mid week.
* Periods of breezy southwest winds through mid week.

.DISCUSSION...Through next Saturday.
Isolated thunderstorms have been developing this afternoon over the
higher terrain of Mohave County as residual monsoon moisture and
decent CAPE remains. Due to the lack of any upper support, these
storms will continue to mainly develop over the terrain and propagate
northeast. Even with the overall decrease in PWAT, the threat of
localized isolated flash flooding will still exist through sunset.
Storms that are able to form west of the Colorado River will have
higher DCAPEs to work with, so the threat of gusty outflow winds are
possible this afternoon.
An area of low pressure will move into the Pacific Northwest Monday
bringing a drier southwest flow to the region. Most of the area will
remain dry, but some isolated storms will still be possible across
far eastern Mohave County. The remainder of the area will see sunny
skies along with some breezy winds. As the trough continues to moved
inland, temperatures become 5-10 degrees below seasonal normals by
midweek. This means highs in the low 90s to upper 80s for Las Vegas.
The drier air will also bring more relief overnight with cool
morning lows, including temperatures in the low 70s in Las Vegas by
midweek. Temperatures may start to increase again towards next
weekend as the low exits east and heights aloft begin to rise.

.AVIATION...For Harry Reid...For the 06Z Forecast
Package...Southwest winds tonight will generally remain around 8KT,
with lighter winds possible early Monday morning. Breezy south to
southwest winds are expected again Monday late morning through the
afternoon, with gusts to around 20KT expected. The strongest gusts
should be after 20Z. Winds are expected to diminish after sunset
Monday, but will remain elevated around 10KT. VFR conditions with
temperatures under 100F expected through the TAF period.
For the rest of southern Nevada, northwest Arizona and southeast

confidence in the BIH TAF as visibility restrictions and occasional
low CIGs due to smoke continue through the night. Improvement in
conditions is possible Monday morning, but more likely in the
afternoon after 18Z when southeast winds return. Smoke and impacts
may return Monday evening as winds turn west then north and push
smoke back into the area. Otherwise, VFR conditions expected
