Synopsis 21 1243 pm.
Hot temperatures are expected through much of next week as high
pressure builds over the area. Night to morning low clouds and fog
is expected across coastal areas, helping temperatures to remain

a thunderstorm has formed over the vta mountains west of lockwood
valley. As a result, have added a slight chance of thunderstorms
to this region as well as the typical eastern san gabriel
mountains with steering currents possibly carrying any storms that
develop into the antelope valley.
***from previous discussion***
latest satellite imagery continued to show the mesoscale
convective system falling apart as it moves into southern nevada
early this afternoon. Outflow from this disturbance has sent a
fairly solid shield of high level cirrus clouds over la county
this afternoon. There also have been some buildups across the
typical la and ventura county mountain locations, however with
limited available moisture, showers and thunderstorms are not
anticipated. Low clouds are parked just offshore of the central
coast with better clearing south of point conception. The high
clouds associated with the disturbance are expected to push out of
the region this evening and give way to mostly clear skies. The
one exception being a return of night to morning low clouds to the
The main story through Tuesday continues to be the building heat.
A very strong 600 dm ridge of high pressure is still expected to
park itself over arizona Monday and stick around through
Wednesday. This combined with offshore flow from the north and
only weak onshore flow to the east will support significant
warming to the region. Sunday is expected to be a transition day
with areas above and inland from the marine layer kicking off the
warming trend with highs already into the 90s to around 100. By
Tuesday 597 dm 500 mb heights overhead will likely squash the
marine layer to the immediate coast at best, with significant
warming just about everywhere. High temperatures Tuesday will
likely be a dangerous 100 to locally 110 coastal valleys and
further inland. Highs in the 90s to near 100 are likely across
inland coastal sections, hottest south of point conception. A heat
warning continues, in effect Monday through Thursday for areas
south of point conception due to the extended heat wave with a
watch to the north of point conception due to lower uncertainty
(see npwlox for the latest).
Advisory sundowner winds are possible as early as Sunday evening
and likely by Monday and Tuesday evenings (sba-smx gradient
peaking near -5 or stronger) focused from gaviota to goleta.
Breezy but likely sub- advisory northerly winds are also likely in
the mountains of la and vta counties near the i-5 corridor by
Tuesday evening. The hot and dry conditions will lead to
widespread elevated fire weather concerns with critical fire
weather conditions possible for areas with sundowner winds where a
fire weather watch is now in effect for Tuesday late afternoon
through Thursday morning (see rfwlox for the latest). The offshore
flow will likely remove low clouds south of point conception by
Long term (wed-sat) 21 200 pm.
Potential for record breaking heat continues into the long term
with excessive heat watches warnings continuing through Thursday
(again see npwlox for the latest). The aforementioned ridge of
high pressure is expected to gradually break down while shifting
nearly overhead through Thursday before shifting northeast into
the interior. This will support continued hot conditions for
interior areas through Thursday before gradual cooling commences
heading into next weekend. Closer to the surface, gusty and
possibly advisory level sundowner winds may continue for western
portions of the sba south coast into Wednesday or Thursday evening
with breezy but sub- advisory winds also possibly continuing in
the la and vta mountains near the i-5 corridor. Once these winds
relax, models are indicating the development of a moderate eddy
circulation by Thursday or Friday which could bring significant
cooling and moistening of the lower atmosphere to the coastal
plain, especially south of point conception. It may also mark the
return of more widespread night to morning low clouds to these
If the ridge of high pressure does reposition near the great basin
in nevada, it would open the door for a potential return of
monsoonal moisture to the region.

At 00z, the marine layer depth was around 900 feet deep at klax.
The top of the marine inversion was around 1300 feet with a
temperature near 21 degrees celsius. There was another inversion
up to around 4000 feet.

Highest chance of lifr conditions expected between 07z and 15z.
Conditions will improve toVFR between 15z and 17z, possibly
lingering along the shoreline into the afternoon on Sunday.
Klax... There is an 80 percent chance of MVFR conditions spreading
into klax between 04z and 09z. There is a 10 percent chance of ifr
conditions between 04z and 07z. There is a 20 percent chance that
vfr conditions could delay until as late as 20z.
Kbur...VFR conditions are expected throughout the period.
Marine 21 123 pm.
Generally good confidence in the current forecast. For the
southern two outer waters zones (pzz673 pzz676), small craft
advisory (sca) winds are not forecast thru sun, then there is a
60%-70% chance of at least SCA winds Sun night thru thu, with a
30% chance of gale force winds at times. For the northern outer
waters zone pzz670, SCA conds are not expected thru Sun night,
then these conditions are likely (60%-70% chance) for Mon thru
thu, with a 20%-30% chance of gale force winds at times Wed and
For the inner waters N of point conception, SCA conditions are
not expected thru Mon morning, then SCA conds are likely mainly
for each afternoon and evening Mon through thu.
For the inner waters S of pt conception, SCA winds are not expected
for pzz655 thru wed, except for a 40% chance of these winds sun
night for western portions. In the sba channel, pzz650, SCA winds
are not expected through mon, then there is a 40%-50% chance of
sca conds across western portions Mon night thru thu, especially
afternoon and evening hours.
Choppy short-period seas will persist across much of the waters
at least through sun.
A long-period south swell from the southern hemisphere is expected
to move into the waters early next week, with 3-4 ft swell possible.
Fire weather 21 336 pm.
Some residual monsoonal moisture with instability will bring isolated
thunderstorm activity to the mountains of los angeles and ventura
counties and antelope valley through early evening. A strong upper level high
pressure system building over southwest california will bring a long
duration heat wave Sunday through at least Friday, peaking in
strength from Monday through Thursday. High temperatures between 100
and 110 degrees will be common in the valleys, lower mountains, and
deserts during the peak, with humidities likely falling to between
10 and 20 percent by Tuesday. Several nights of gusty sundowner
winds are expected across southern santa barbara county from
Sunday night through Wednesday night when gusts between 30 and 45
mph will be common across western portions, with isolated gusts as
high as 50 mph near gaviota and refugio hills. These persistent
gusty sundowner winds will add to the fire weather threat across
southern santa barbara county, with conditions potentially
reaching critical levels by late Tuesday when humidities fall
between 10 and 20 percent and temperatures potentially climb to
around 100 degrees. The projected sba-smx gradient for Sunday
night is -4.6 mb, and could reach or exceed -5 mb on Monday night,
Tuesday night, and Wednesday night. A fire weather watch has been
issued for the santa barbara south coast and mountains. Breezy
northwest to north conditions are also expected across the
interstate 5 corridor in the los angeles county mountains.
The long duration of hot and dry conditions coupled with dry fuels
will bring an increased risk of large vertical plume growth across
interior sections next week, especially in the foothills and
mountains. Widespread elevated fire weather conditions will occur
next week across southwest california due to the long duration heat
wave. Very warm overnight low temperatures and poor humidity recoveries
in the foothills and mountains will add to the fire weather threat
in those areas.
Lox watches warnings advisories
Ca... Excessive heat watch in effect from Tuesday morning through
Thursday evening for zones 34>38-51. (see laxnpwlox).
Excessive heat warning in effect from 10 am Monday to 8 pm
pdt Thursday for zones 39>41-44>46-52>54-59-88-547. (see laxnpwlox).
Fire weather watch in effect from Tuesday afternoon through
Thursday morning for zones 239-252. (see laxrfwlox).
Hazard potential outlook (tue-sat)
An extended heat wave is expected Monday through at least
Thursday of next week, especially for inland areas. Widespread
elevated fire weather conditions are expected to develop during
this time. Elevated to high surf is likely Monday through
Wednesday, focused across south facing beaches.
