.KEY MESSAGES...

* Cooling temperatures and gusty north winds expected for the
  latter half of the weekend. Cooling, breeziness, and
  precipitation chances return midweek.

.DISCUSSION...Today through Friday.

The Desert Southwest will sit beneath a northwest flow through the
forecast period. The latter half of this weekend, this northwest
flow will allow for the passage of a shortwave trough, which will
drop temperatures by 4 to 6 degrees between Sunday and Monday and
will increase northerly afternoon breezes (10-20 mph areawide, with
25-35 mph in the Colorado River Valley) Monday afternoon. These
northerly winds will result in wave heights in excess of 2 feet on
Lake Mohave, particularly near Katherine Landing, which will result
in hazardous boating conditions for small craft. Otherwise, expect
additional shortwave passages to return breezy afternoons to the
region through the week. The most robust shortwave looks to drop
through the southern Great Basin and Mojave Desert midweek. The
current trajectory indicates that the system will pick up meager
amounts of moisture, which will increase cloud cover and relative
humidity across the region Wednesday and Thursday. Though slight
precipitation chances exist for the region midweek (20-30%),
accumulations will be negligible, with impacts being slick roads
from very light rain and ruined car washes. That said, slight
changes in the trajectory could result in greater precipitation
amounts, so stay tuned to the forecast if traveling or planning
outdoor activities. Expect a return of gusty north winds (15-25 mph)
Wednesday and Thursday as the associated cold front passes through
the forecast area.
