.DISCUSSION...Today through Saturday.

The northwest flow aloft continues through the forecast period.
Today and Monday, this northwest flow will allow for the passage of
a shortwave trough, which will drop temperatures by 4 to 6 degrees
between this afternoon and Monday afternoon and will increase
northerly afternoon breezes (10-20 mph areawide, with 25-35 mph in
the Colorado River Valley) Monday afternoon. There is a 30% chance
of an isolated gust at or above 40 mph near Laughlin-Bullhead City,
but those speeds are not expected to be widespread in space or time,
so no wind-related headline is necessary. 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. As mentioned in the previous
forecast discussion, Tuesday morning will be the coolest point in
the forecast period, with an 80% chance of freezing temperatures in
lower elevations of eastern Inyo County (particularly near Shoshone-
Tecopa); as such, issued a Freeze Watch from 1am through 8am Tuesday
morning marking their first freeze of the season. Other areas to
consider include the lower elevations of the Mojave National
Preserve and lower elevations of southern Mohave County, where there
exists a 30-40% chance of reaching freezing temperatures Tuesday
morning. No freeze headline issued for these zones at this time, but
will continue to assess with future shifts.

Another shortwave will drop through the southern Great Basin and
Mojave Desert on Wednesday. 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.
Precipitation chances have decreased areawide, with slight chances
of measurable rainfall (10-20%) confined to the higher elevations of
the southern Great Basin. Accumulations, if any, will be negligible.
Expect a return of gusty north winds (15-25 mph) Wednesday and
Thursday as the associated cold front passes through the forecast
area. Temperatures moderate heading into next weekend.
