Updated fire weather discussion...
An upper level trough off the california coast will weaken high
pressure aloft starting this afternoon and bring a cooling trend
as onshore flow strengthens. One more day of very warm
temperatures expected inland before cooling down to more normal
highs for this time of year by midweek. Expect low clouds and fog
to redevelop after today and continue through the week.
Short term (tdy-wed)
given yesterday's unexpected major heat up in the la valleys due
to the west northwest winds and that we're still expecting at
least some westerly flow again today it looks like those same
areas are in for a similar though likely less intense warm up
today. Light sundowners expected again this evening in SRN sb
county that will drive the temps up there as well. Could see some
temps near 90 close to the beach as the winds start kicking up. So
overall a pretty warm day on tap.
Tonight low clouds will again struggle to form south of pt
conception but we should see a return of a more solid stratus
layer along the central coast.
***from previous discussion***
tue and Wed the upper ridge lingers over the region, but it
weakens as an upper trough moves across much of the west coast
both days. The combination of stronger onshore gradients, cooling
boundary layer temps and a deeper marine layer, will bring
widespread cooling across the entire forecast area with best
cooling across la vtu counties. High temps will be just above
normal for this time of year, with the antelope valley finally
going below 100 after a number of days well into triple digit
heat. Valleys will be in the 80s for the most part, with a few
lower 90s across warmest locations. Wednesday should be the
coolest day of the week with high temps right where they should be
for most areas. Night through morning low clouds will continue and
likely reach the coastal valleys from Tue night through much of
Long term (thu-sun)
looking fairly uneventful through the long term. Both the GFS and
ecmwf are in good agreement with large scale features through the
long term period. Overall, there will be weak troughing across
much of california with a building ridge off to the sw. It looks
like it will have enough strength to throw a 591 dm high over
socal briefly Friday before it weakens and NW flow aloft persists
into the weekend. So expect similar conditions Thursday from
Wednesday with minor temperature fluctuations, then a brief modest
warming for Friday, with a modest cooling trend into the weekend.
Overall, not much change. Expect night through morning low clouds
to continue across coast and likely some coastal valleys into late
this week and weekend.
Aviation 26 12z.
At 08z at klax... The inversion was around 1050 feet. The top of
the inversion was around 2150 feet with a temperature of near 33
Overall... Moderate confidence in the current coastal tafs and
high confidence in the interior tafs. Patchy low clouds and fog
will develop along the coast 11z-16z... Primarily along the
central coast. There is a twenty percent chance of mfr conditions
developing at some locations near daybreak. Any reduced
conditions will improve toVFR by 18z. Otherwise and elsewhereVFR
conditions will prevail.
Klax... Moderate confidence in the current tafs. Patchy low clouds
and fog will develop 11z-16z. There is a less than ten percent
chance of mfr conditions developing near daybreak. Any reduced
conditions will improve toVFR by 17z. OtherwiseVFR conditions
will prevail. No east winds greater than seven knots are expected
during the forecast period.
Kbur... High confidence in the current tafs.VFR conditions will|
prevail throughout the period.
Marine 26 900 am.
High confidence in small craft advisory (sca) conditions from the
central coast to san nicolas island through at least Thursday.
The strongest winds of the period will be today and tonight.
Moderate confidence in low end scy conditions over the santa
barbara channel and santa monica basin through tonight... With
similar but slightly weaker winds on Tuesday. The stronger winds
will generally be over the western portions of these areas, but
the winds should be fairly widespread this afternoon and evening.
There will be lulls each morning within 10 miles from the coast,
but the scy will extend through those lulls to highlight the
extended period of gusty afternoon and night winds.
Two distinct wave types will be observable over the waters, with a
long period (13-15 seconds) south to southwest swell through
Tuesday, and a short period (6-8 second) west swell mixing well
with any wind waves. The buoys will likely highlight the long
period swell, but the short period swell will be most noticeable
and will be highlighted in the forecast. By the middle to end of
the week, the short- period west swell will dominate as the south
Fire weather 26 930 am.
Relative humidity readings are noticeably lower this morning
across much of the area with a broad area of values of 15 percent
or lower across a good portion of the los angeles county
mountains, the antelope valley and even westward over a portion of
the ventura county mountains. West and southwest winds with this
very dry area are currently gusting between 20 and 30 mph and are
expected to increase later this afternoon and be fairly similar to
yesterday's value as pressure gradients are very similar to
yesterday, the difference today being the drier air that's now in
place. Red flag conditions are still possible this afternoon and
early this evening across the los angeles county mountains, the
antelope valley, but to a lesser extent in the santa clarita
valley. The continued hot temperatures will continue to bring an
enhanced threat of plume- influenced fires. Winds are expected to
subside later this evening with enough increase in moisture to
reduce the threat of fire weather conditions. Fire weather
conditions are expected to be improved on Tuesday, although an
elevated threat is expected to remain over mainly the los angeles
Another area to monitor the next couple of evenings is across
western portions of the santa yznez range and the south coast from
mainly from gaviota to goleta, with gusts of 30 to 40 mph this
evening and Tuesday evening. In addition, localized humidities
falling to between 15 and 25 percent can be expected in the santa
ynez mountains and adjacent canyons where the moderate downslope
sundowner winds develop.
