.SYNOPSIS...04/746 PM.

Onshore flow will continue to bring low clouds to the coasts and
coastal valleys each night through morning. Onshore flow will
start to weaken Monday and cause decreasing clouds in the valleys
and gradually warming temperatures. Expect a return to above
normal temperatures early next week.

.SHORT TERM (SAT-TUE)...04/813 PM.

***UPDATE***

There is around a 5 to 10 percent chance of brief showers or
thunderstorms this evening and overnight, mainly over areas north
of Point Conception. However, there are non-zero chances over
northern LA County and the Ventura Mountains as well. This is in
response to subtropical moisture moving northward over the area,
along with a weak disturbance aloft. Wetting rain (0.10 inch or
more) is not expected, however there is a low risk of dry
lightning and/or gusty erratic outflow winds.

The high clouds streaming over the area helped to disrupt the
marine layer earlier today resulting in fewer coastal low clouds
for Ventura and LA Counties. While a similar low cloud pattern is
expected tonight into early Sunday, there is a chance that the
upper disturbance will prevent any organized low cloud formation
along the Central Coast.

As for temperatures, expecting a slight cool-down Sunday due to
slightly lower heights aloft and increasing onshore flow. This
will be followed by warming Monday and especially Tuesday through
Thursday with strong high pressure building aloft and onshore
flow weakening considerably. Heat Advisories will likely be needed
for much of the area, especially Wednesday and Thursday. Highs in
the 80s to mid 90s are expected away from the coast Sunday,
rising into the 90s to above 100 degrees starting Tuesday.

Through Monday, onshore winds gusting up to 35 mph are expected
for the Antelope Valley and Foothills, along with Sundowner winds
Sunday through Wednesday, with peak gusts up to 40 mph.

.LONG TERM (WED-SAT)...04/1224 PM.

Above normal temperatures and dry weather are anticipated through
the extended periods as high pressure strengthens aloft helping
to aid in a continued warming trend across the region.

At this point, the upper level ridge looks to be centered across
southern California over the Wednesday/Thursday time period, when
afternoon temperatures should peak. The ridge is then expected to
shift north and east by the end of the week and over next
weekend, providing some minor relief to end the week. That said,
temperatures are still expected to remain well above average to
end the current forecast period, and likely beyond - with CPC
outlooks continuing to favor above normal temperatures through at
least week 2.

Given the anticipated warm up, there will be at least a minor to
moderate heat risk each day, with about a 70% chance that heat
advisories will eventually become necessary Tuesday-Thursday
across mainly inland areas including the San Fernando and Santa
Clarita valleys.

Finally, an increased surface pressure gradient early next week
will also likely result in a return to modest sundowner winds
both Tuesday and Wednesday nights.
