.DISCUSSION...through Tuesday.

Breezy north winds will linger down the Colorado River Valley for
one more day before the pressure gradient relaxes as a ridge of high
pressure settles over the area. These northerly winds will peak
between Laughlin/Bullhead City and Needles, where 15 to 20 mph
sustained winds gusting to 25 to 30 mph are expected. While the
magnitude of these winds remains well below Wind Advisory criteria,
they will be enough to produce 1 to 2 foot waves on Lake Mohave this
afternoon resulting in hazardous boating conditions for small water
craft. Outside of these breezy north winds in the Colorado River
Valley, dry, mild, and warm weather will continue across the region
through Friday.

A shortwave will begin to erode at the upper-level ridge on Thursday
and Friday as it moves through the Pacific Northwest before digging
southeast into the Four-Corners Region and ejecting into the Central
Plains. This shortwave will open the door for more systems to drop
into the area as we find ourselves under northwestern flow aloft.
Another system will drop into the area over the weekend, bringing
cooler temperatures to the area. Over the past 24 to 36 hours, this
system has trended drier and drier as global ensembles converge on a
more inland track. The way things currently sit, the most impactful
weather phenomena associated with this system will be the 8 to 12
degree cool down from Friday to Sunday. Northwesterly flow aloft
will persist through early next week, leaving the door open for
additional low pressure systems to move through the area.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will remain under 10 knots, following typical daily directional
trends. VFR conditions will persist through the TAF period with high

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds across most of
the region remain light, following typical daily directional
patterns. The exception is the lower Colorado River Valley where
northerly winds gusting to 15-30 knots are expected, primarily
during the daytime hours. VFR conditions will persist through the
TAF period with high clouds AOA 20 kft filtering through the area.
