.SYNOPSIS...06/850 AM.

Night through morning low clouds and fog will continue for the
next several days over the coast and valleys with slow, if any,
clearing at the coast. Cooler than normal temperatures are
expected today, then a warming trend will develop for the weekend
and through next week, especially away from the beaches.

&&

.SHORT TERM (TDY-MON)...06/137 PM.

An upper low over the Bay Area is expected to be nudged a few
hundred miles over the Pacific which will allow heights and
thicknesses to rise over the weekend into Monday, leading to a
decreasing marine layer depth and 1-3 degrees of warming each
day, especially inland. High temps expected to reach the low to
mid 90s in the warmest valleys while coastal areas are in the
upper 60s and 70s. No impactful weather expected except possibly
some dense fog along the Central Coast and some of the LA/Ventura
valleys and some breezy afternoon/evening winds across the deserts
and southwest Santa Barbara County.

.LONG TERM (TUE-FRI)...06/201 PM.

One additional day of warming is expected on Tuesday as the upper
low moves into AZ while a little ridge pops up over CA. Highs
will top out around the mid 90s for coastal valleys and around
100 in the Antelope Valley. Not expecting temperatures to be high
enough for heat advisories.

Then a slow cooling trend the rest of the week as a trough
develops over the Pac NW.

.AVIATION...06/1850Z.

At 18Z at KLAX, the marine layer was 2500 feet deep. The top of
the inversion was at 3900 feet with a temperature of 21 C.

High confidence in VFR TAFs for KPMD and KWJF.

Moderate confidence in all remaining TAFs with timing of flight
category changes possibly off by 2 hours and 1 flight category at
times. Except for KPRB, which has a 20-30 percent chance of
IFR/LIFR cigs/vsbys between 10-16Z. There is a 10-20 percent
chance that VFR conds prevail at KVNY and KBUR.

KLAX...Moderate confidence in TAF. No significant east wind
component expected.

KBUR...Moderate confidence in TAF. There is a 10 percent chance
that VFR conds prevail.

&&

.MARINE...06/150 PM.

Typical northwest to west winds are expected this weekend,
especially across the waters south of Point Conception. There is a
20% chance of Small Craft Advisory (SCA) winds across western
portions of the Santa Barbara Channel this afternoon and evening.

There is increasing chances for SCA winds across the waters
around Pt. Conception, Northern Channel islands, and down to San
Nicolas Saturday (40%) into Sunday (60%). Short period choppy seas
are likely nearshore.

Next week will be characterized by increasing chances and coverage
for SCA winds across the outer waters, pushing into the western
portion of the southern inner waters at times, and seas building
towards SCA levels mid- week and beyond. Confidence is low (seas)
to moderate (winds).

Dense fog may become more common this weekend into early next week
focused north of Point Conception and especially during the
evening to morning hours.
