Synopsis
Cooler weather this weekend will turn very hot inland next week
as high pressure builds over the southwest. At the same time,
coastal low clouds making an appearance as far as the valleys
during nights and mornings will retreat to the coast.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

mostly sunny skies and cooler than average weather are with us
this afternoon. A deepened marine layer will again allow low
clouds and fog to push ashore relatively early this evening and
push inland overnight. Clouds could nearly fill the coastal basin
tonight much as they did last night. Low pressure aloft,
responsible for our deeper marine layer, will lift out and high
pressure from the east will gradually press down over the
southwest over the next few days. That will bring us a noticeable
warming trend starting Monday that will peak in a heat wave
Wednesday and Thursday very similar to the heat wave we had this
past week. High temperatures through Monday will come in a little
below average for most areas, but will climb above average inland
by Tuesday and 5-10 degrees above average on Wednesday and
Thursday, the projected hottest days. The high pressure aloft
weakens ever so slightly Thursday into next weekend. Temps will
begin a modest decrease, although it will still be plenty hot
inland. Monsoon moisture begins to show itself toward next
weekend, but nothing to really forecast about yet. You may be
hearing about some model guidance bringing a hurricane up the west
coast of mexico. There is a forming tropical depression south of
guatemala that is shown by some guidance to grow into a hurricane,
then move west and northwest along the mexico coast. It parallels
baja california early the following week (around 26 aug). It's
something interesting to watch, but there's little if any chance
of impact on socal weather.

Aviation
171920z... Coast valleys... Skc with unrestricted vis this afternoon.

Low clouds likely returning to coastal TAF sites between 03z and 06z
with bkn-ovc bases around 1500 ft msl and tops to 2500 ft msl,
spreading up to 30 miles inland overnight. Local vis 1-3 miles where
clouds and terrain intersect. CIGS and reduced vis could reach kont
and ksbd between 12z and 15z Sunday. Clearing at kont and ksbd
expected around 16z and at coastal TAF sites between 17z and 18z
Sunday.

Mountains deserts... Sct clouds at or abv 20000 ft msl and
unrestricted vis through Sunday. W winds gusting 25-35 kt over mtn
crests and through passes, producing weak to mdt up downdrafts and

expected at kpsp and ktrm.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
