Monday.

3. Strong wind gusts are favorable to return to the Mojave
Desert Slopes again today and Saturday.

.DISCUSSION...
Current satellite shows some high clouds rapidly moving to the
northeast, up the windward side of a high pressure ridge parked
over the southwest of the CONUS, while marine clouds shift to
the south ahead of a cold front moving in from the Pacific. This
cold front is associated with a low pressure system located up
in Canada. This cold front will cross our CWA tonight, resulting
in a slight cooling of afternoon highs and cause some breezy
winds along the Mojave Slopes today and again tomorrow as a weak
low passes through the region.

A return to ridging is expected for a short time on Monday,
with highs forecast to be well above average. Soon after, a
trough is expected to come down from the pattern above the
Pacific on Tuesday and be pulled lower by leftover energy above
California. This may result is a cutoff low being formed, and a
small amount of moisture may be pulled in and mountain showers
or thunderstorms with a 10 to 15 percent chance. A ridge may
then build in on top of that cutoff, which would hold it in
place into next Friday, resulting in a slow cooling of
temperatures, though highs are expected to remain in the 80's in
the Valley through the next week. There is also the possibility
that highs in the Valley dip into the high 70's next Friday,
with a 30 to 40 percent chance of highs less than 80 degrees in
the Valley.
