Synopsis 15 712 am.

Conditions will be warm and dry today then cooler tomorrow.

Onshore flow returns this weekend and will bring overnight and
morning low clouds and fog to the coast and adjacent valleys into
early next week and near normal temperatures through the week.

Short term (tdy-sun) 15 1235 pm.

Pretty quiet next few days on tap as gradients weaken and
eventually turn lightly onshore Friday. The NAM has been
consistent showing an increase in marine layer stratus from the
south tonight as a weak eddy circulation develops. Mainly just
southern la county tonight with possibly some dense fog as the
inversion is very low. Stratus will spread much farther north by
Saturday as southerly flow pushes it up the coast and around pt
conception. All this will bring a cooling trend to the area,
especially coast and valleys with highs dropping back down into
the 60s and 70s. By Sunday gradients will start flipping back
around to offshore as a trough passes through the northern rockies
and surface pressures rise over the great basin. This should help
warm things up a few degrees for coast valleys but still topping
out in the mid 70s which is pretty close to normal for this time
of year.

Long term (mon-thu) 15 1242 pm.

Next week's forecast still quite a bit uncertain, particularly mid
week on. Monday and Tuesday still quite confident in dry
conditions and a slight return of offshore flow, though quite a
bit weaker than we've seen recently. Gradients are at most half of
what they were with this last event and little if any upper
support so no real concern yet for gusty winds or critical fire
weather conditions. But should be enough to warm temps a few more
degrees Monday then leveling off Tuesday as onshore trends return.

Forecast gets messier after Tuesday as the medium range models
continue to have significant differences.

The ECMWF still has some light precip coming in Wed with a weak
trough while the GFS has a decent ridge over the west coast at
that time. Since none of the GEFS members show anything close to
this solution am discounting the ECMWF in favor of the dry GFS for
Wednesday. After that both models keep it dry until Thursday night
and Friday when the next trough arrives. Though here again there
are significant enough differences to have pretty low confidence
in timing and strength. Odds favor at least a little rain during
that time frame but still too early to get specific.

Aviation 15 1731z.

At 17z at klax, there was no marine layer. There was a surface
based inversion with a top of 1000 ft and a temperature of 20c.

High confidence inVFR everywhere through this evening. Lifr fg
will likely form over the waters late tonight, with a 40 percent
chance of impacting klgb klax ksmo, and 20 percent chance at koxr
kcma ksba. Gusty NE winds will be weakening today.

Klax... High confidence inVFR through this evening. 30 percent of
lifr fg 12-17z Friday. High confidence in any east winds staying
under 7 kt.

Kbur... High confidence inVFR through Friday with light winds.

Marine 15 921 am.

High confidence in winds staying below small craft advisory (sca)
through at least the weekend. Dense fog with very low visibility
is possible late tonight and Friday, especially south of point
conception including the san pedro channel.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (sun-thu)
No significant hazards expected.
