Synopsis
A low will bring an overnight coastal marine layer, otherwise mostly
clear skies into next week. The temperatures will be around normal
into midweek. Then a high will move in for a warming trend from
Friday into next week, with Monday and Tuesday the peak heat days.

Short term (tdy-fri)
very minimal marine lyr this morning but it's starting to make a
return along the central coast this afternoon. Models also show
moisture filling in below the inversion base south of pt
conception tonight as well so better coverage overall is expected
by Wednesday morning. Along with this there is a 1-2mb onshore
trend. So in addition to an increase in low clouds tomorrow most
coast valleys should be a degree or two cooler as well for highs.

After that we should begin a slow warming trend through the rest
of the work week. Gradients trends weakly offshore each day
leading to a weaker onshore flow.

Long term (sat-tue)
little change or slight warming Saturday, then more significant
warming as we get into Sunday, Monday, and especially Tuesday
where light offshore flow could finally bring some of that inland
heat to the coast. Warmer valley spots should see triple digits by
Sunday and likely 105 or higher by Tuesday. Inland coastal areas
like downtown la probably won't see 90 until Monday or Tuesday but
still above normal by Sunday. Temps expected to keep on climbing
through most of next week as well, possibly leading to some heat
advisories and or excessive heat warnings by as early as Tuesday.

Models still so far not showing any monsoon moisture with this
heat wave so thunderstorms remain out of the forecast.

Aviation
22 0000z
at 2345z, the marine layer at klax was near 1500 feet deep. The
top of the inversion was 3600 feet with a temperature of 26 degrees
celsius.

Good confidence in tafs ksba and south through 08z. Then fairly
low confidence from 08z to 13z as timing of low cloud arrival
could be off by 2 hours. Lower confidence for coastal TAF sites
cloud dissipation as well with a 30 percent chc of no clearing.

Moderate confidence in central coast tafs timing may be off by + -
1 hour.

Klax... Good confidence through 08z then low confidence. Ifr cigs
could arrive any time from 08z to 11z. There is a 30 percent chc
of no afternoon clearing.

Kbur... High confidence through 08z then low confidence. Ifr cigs
could arrive any time between 10z and 13z. There is a 20 percent
chc of no CIGS at all.

Marine
22 100 pm
for the outer waters, good confidence in current forecast. Rather
smooth conditions through Wednesday, then northwest winds increase
Thursday and Friday before decreasing late Saturday. Small craft
advisory (sca) levels will likely develop Thursday afternoon with
building seas to around 7 ft into Saturday morning. There will be
a small S swell mixed with the w-nw swell at times.

For the inner waters, good confidence in the current forecast.

For the waters north of point sal, winds and seas will remain
below SCA levels through Wednesday. On Thursday and Friday, sca
level winds are likely each afternoon and evening with winds
diminishing below SCA levels on Saturday and Sunday. For the
waters south of point conception, winds and seas are expected to
remain below SCA levels through the weekend.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (fri-tue)

continue into early next week.
