200 pm pdt Tue apr 24 2018

Synopsis 24 130 pm.

High pressure over the great basin will bring another mild day
Wednesday, then drift east Thursday and Friday. A trough of low
pressure over the pacific will bring minor cooling through Friday as
it moves across northern california. This trough will stall and
deepen along the coast over the weekend bringing further cooling and
increasing night and morning low clouds.

Short term (ton-fri) 24 130 pm.

The overall weather trend through Friday is for gradual cooling and
a deepening marine layer as a trough of low pressure over the
pacific moves inland across northern california. Wednesday will be a
lot like today, mild inland with scattered high clouds, with a high
amplitude ridge over the great basin. Closer to the coast, the
morning low clouds and fog will retreat back to the coast through
midday but like today they may not completely clear from the
beaches. Highs tomorrow will be a few degrees lower than yesterday
for most areas, except for the antelope valley where it will
probably be just as warm tomorrow as it was today.

Inland surface pressures gradually lower from 1018 mb today to 1013
mb Wednesday to 1008 mb Thursday resulting in stronger onshore flow
and stronger winds each day. The winds will strengthen each day with
gusty west winds across the foothills, mountains and the antelope
valley. Advisory level sundowner winds are likely for western
portions of the sba south coast Thursday evening, before becoming
more widespread across the region Thursday night into Friday
morning. The marine layer will deepen with night and morning low
clouds spreading farther inland each night.

Rain chances remain low. The trough axis moves across
northern central ca Thursday night and Friday with PVA and modest
instability, but the moisture fields will be the limiting factor in
any precip potential over the higher terrain. Will keep the forecast
dry at this time.

Long term (sat-tue) 24 130 pm.

Pulses of shortwave energy will deepen the trough down the west
coast for continued cooling through Monday. Temperatures will fall
below average, and gusty winds will impact the mountains and
deserts. Monday looks to be the coldest and most unstable day as the
cold core 500 mb low settles over the region. This looks to be our
best day to see scattered showers, but will wait for more model
consistency before committing.

Aviation 24 2030z.

At 2000z at klax, the marine layer inversion base was at around 1200
ft and the top was near 2200 ft with a temperature around 19 c.

Moderate confidence in tafs this afternoon. There is a good chance
sba will temporarily clear this afternoon. Stratus bases and tops
tonight should be similar to this morning, with low vis where
clouds near higher elevations.

Klax... Moderate confidence in taf. Stratus development may occur
earlier than forecast this evening.

Kbur... Good confidence in taf. There is a 30 percent chance of
vfr conds Wednesday morning.

Marine 24 115 pm.

Winds will likely increase to small craft advisory criteria Thursday
through Saturday, along with building short period seas as upper-
level low pressure approaches the region. Otherwise, no hazardous
marine weather conditions expected through Wednesday.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (fri-tue)
No significant hazards expected.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
