.DISCUSSION...Today through Sunday.

Ridging continues through much of the work week, resulting in quiet
weather, dry conditions, and generally light winds. The exception
will be along the Colorado River Valley where gusty north winds will
elevate as a result of a weak shortwave passage along the flow
aloft. These gusty winds will occur on Tuesday and Wednesday
afternoons with speeds between 25 and 35 mph, which will increase
wave heights on Lake Mohave and Lake Havasu to 1 to 3 feet.
Otherwise, temperatures will remain well-above normal through the
forecast period, with afternoon highs 10 to 15 degrees above
seasonal normals.

Through the week, ensemble means continue to show a closed low off
the coast of Baja California slowly moving northward along the
shoreline. Late-week, this low will weaken into an open wave, phase
with another incoming system from the eastern Pacific, and will push
into the Desert Southwest. Details remain uncertain at this time,
with ensemble ECMWF means favoring a swath of light rain across the
Mojave Desert and ensemble GFS means favoring hit-or-miss sprinkles.
This pattern change continues into the start of next week as
troughing returns to the western CONUS.
