132 AM PST Mon Dec 11 2023

.SYNOPSIS...Partly to mostly cloudy skies expected through Tuesday
morning as high-level moisture moves through a ridge. Midweek, a
trough will push through the southwestern United States, returning
northerly wind gusts to the area. Otherwise, temperatures will
remain above average for mid-December through the forecast period.

.SHORT TERM...Today and tonight.

Fair weather will continue as a broad swath of high clouds streams
over our region today and tonight underneath a weak trough digging
down from the Pacific Northwest. Light winds and filtered sunshine
will be observed today with temps climbing slightly from Sunday's
values leading to highs in the 60s across the Mojave Desert Region.
The base of the digging trough will drop over much of CA/NV tonight
but will not be noticeable in sensible weather. Winds will remain
light and variable with little variation in overnight lows.

.LONG TERM...Tuesday through Sunday.

Little change in the upcoming pattern as ensemble simulations
remain consistent from yesterday.

Evolving trough across California/Nevada Tuesday will eventually
develop into a closed low over Arizona/Four Corners region Wednesday
and Thursday. Main impact on backside of exiting trough will be a
round of gusty north winds developing Tuesday night into Wednesday.
Winds stay elevated through Thursday within the lower CRV, but
elsewhere they will be subsiding. A wind headline may be needed from
Lake Mohave south to Needles/Mohave Valley Wednesday.

The mid-week system will be dry with little fluctuation in
temperatures through the period.

Harry Reid terminal. Light and variable winds may briefly become
