.SYNOPSIS...Other than isolated showers this afternoon in Lincoln
County, dry conditions will persist through much of next week.
Breezy winds are possible a times, with the strongest winds
expected Monday. Temperatures will remain above normal and slowly
climb each day through the week.

&&

.SHORT TERM...Today through Tuesday.

The upper level low currently over southeast Nevada will lift into
Utah today, weaken as it does so. In addition, 500mb temperatures
will warm at the low`s center, which will limit any instability
today. There is a low (20%) chance for isolated showers in eastern
Lincoln County this afternoon, but impacts are not expected. Further
west, ridging will build into the region which will result in dry
condition. High temperatures today will be 3-5 degrees warmer than
yesterday, with the most significant warm up expected in Inyo and
San Bernardino counties where the greatest height rises are expected.

The ridging will be short lived as another upper level trough is
expected to move into the region on Monday. This system will have no
moisture and limited forcing, so precipitation is not likely.
Increasing winds are expected Monday afternoon as the pressure
gradient increases ahead of the trough axis. Probabilities remain
very low (10% or less) for gusts over 40 MPH across the region on
Monday, so widespread wind impacts are not expected. The Western
Mojave Desert and Morongo Basin will see the strongest winds with
widespread gusts of 30-35 MPH likely. HREF DESI does show pockets of
higher probabilities for gusts over 40 MPH between 5 PM and 11 PM
Monday evening which corresponds with an increase in the low level
jet, but it is should be isolated and brief so impacts would be
marginal and sporadic if they did occur. In general, most areas will
see southwest winds gusting 20-30 MPH Monday, mainly in the
afternoon. The trough will continue to move east on Tuesday thus
weaker winds and no impacts are expected on Tuesday.

Despite the trough moving through Monday and Tuesday, temperatures
will remain warm. High temperatures each day will warm 1-2 degrees
compared to the previous day, with temperatures running 3-5 degrees
above normal by Tuesday afternoon.


.LONG TERM...Wednesday through Sunday.

A cut-off low will approach the southern Californian coast on
Wednesday, settling somewhere off the coast of southern California/
the Baja Peninsula during the second half of the week. While this
system approaches and settles off the coast, a ridge of high
pressure will build over the western US, resulting in an upper-level
pattern resembling a Rex Block. Confidence is high regarding hotter
than normal temperatures during the second half of the week, as even
the 10th percentile of the maximum temperature distribution is
sitting at or above normal through the end of the week. However,
just how hot we end up getting will be dependent on the amplitude of
the upper-level ridge. The exact location of the cut-off low and
when the cut-off low moves inland also contribute to forecast
uncertainty in the long term.
