Synopsis 21 630 pm.
Record breaking heat is possible during the early to middle part
of next week in response to a strong ridge of high pressure
building over the desert southwest.
Short term (tdy-tue) 22 303 am.
The marine layer is 900 feet deep and is capped by a strong and
strengthening inversion. Low clouds have formed nicely over the
central coast but there are only a few patches of clouds south of
pt conception. The low cloud development has been stymied by some
cirrus and weak offshore flow. There will be a little more stratus
formation now that the cirrus is moving out there will be a little
more stratus formation but still think skies will be on the
clearer side of things. Hgts bump up to 594 dm today as the upper
level begins its march to the west. The higher hgts and weaker
onshore flow will allow for decent 3 to 6 degree bump up in temps
everywhere except the central coast where the marine layer will
still hold sway.
Just enough residual monsoonal moisture over the area to warrant a
slight chc of a shower or thunderstorm across the higher peaks of
the la and vta mtns in the afternoon.
The east pac sfc high strengthens tonight and this will increase
the NW to SE sfc flow over sba county. The mdl have been
consistently increasing the forecast smx-sba gradient. It seems
likely that there will be advisory level winds across the sba
south coast this evening and overnight west of goleta. These
southerly winds will keep many overnight lows across the sba south
coast well above normal.
The upper high will move over nm az on Monday and Tuesday. Hgts
will rise to 595 dm Mon and 597 dm tue. The W to E gradients weak
but more importantly the N to S grads turn offshore in the
morning (unlike the last heat wave these gradients do return to
onshore in the afternoon) this will really drive up the temps. Max
temps will generally be 5 to 10 degrees above normal on Monday and
then 10 to 15 degrees above normal on Tuesday.
Another sundown will take place on Monday night and it will be a
little stronger than tonight's. The offshore flow might even
bring advisory level winds to the interstate 5 corridor.
The offshore flow will keep the overnight lows well above normal.
The combination of much above normal daytime highs and overnight
lows (which will give people no respite from the heat) will result
in dangerous heat conditions and excessive heat warnings will go
into effect Monday morning for much of the area. The warm up will
hold off for a day across the central coast and a heat watch is in
effect for that area starting Tuesday.
Hot and dry conditions developing will bring elevated fire
weather concerns the next several days. Critical fire weather
conditions are possible for areas with sundowner winds. A fire
weather watch is in effect from late Tuesday afternoon through
Long term (wed-sat) 22 306 am.
Potential for record breaking heat continues into the long term
with excessive heat watches warnings continuing through Thursday
(again see npwlox for the latest). Both the GFS and the ec
forecast the upper high to gradually break down while moving
directly over socal Wednesday and Thursday before shifting
northeast into the interior Friday and sat. 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
Monsoon flow will once again become possible starting Friday and
Aviation 22 1208z.
At 0816z at klax... The inversion was near 1000 feet. The top of
the inversion was around 1600 feet with a temperature of about 24
Overall... Low to moderate confidence in the coastal tafs and high
confidence elsewhere. Coastal low clouds are slow to develop this
morning in part due to a persistent higher cloud deck. Some
coastal locations have had occasional lapses into lifr ifr MVFR
cigs overnight and most should have a period of CIGS from shortly
prior to daybreak to up to a few hours afterwards. These conditions
are not expected to last for long, though that higher cloud deck
could slow dissipation. Otherwise and elsewhereVFR conditions
Klax... Low to moderate confidence in the current taf. Coastal
low clouds are slow to develop this morning in part due to a
persistent higher cloud deck. However there will be a period of
ifr MVFR CIGS from near daybreak to up to a few hours afterwards.
These conditions are not expected to last for long, though that
higher cloud deck could slow dissipation. OtherwiseVFR conditions
will prevail. East winds greater than 8 knots are not expected
during the forecast period.
Kbur... High confidence in the current taf.VFR conditions will
prevail throughout the forecast period.
Marine 22 307 am.
For the outer waters... West to northwest winds will increase to
small craft advisory (sca) level by this afternoon across the
central and southern outer waters. The elevated winds will
continue through at least late Tuesday and may increase to gales
at times. There is a forty percent chance of the winds in the
northern outer waters reaching SCA level on Monday.
For the inner waters north of point conception... SCA conditions
are not expected through Monday morning then become more likely
during the afternoon and evening hours of Monday through Thursday.
For the inner waters south of point conception... SCA level winds
will develop this afternoon through late tonight across the santa
barbara channel then have a forty percent chance of developing each
afternoon and evening through Wednesday. There is a 30 percent
chance of similar conditions across the nearshore waters south of
Beaches 22 215 am.
A long-period southerly swell will be moving through the coastal waters
this weekend producing strong rip currents and high surf conditions at
southern california beaches Monday through Wednesday

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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
