  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.
