Synopsis Dry conditions and seasonably warm daytime
temperatures will continue through the weekend with marine air
keeping conditions cooler near the coast. A more robust warming
trend is then expected later next week, especially across inland
areas, as as strong ridge of high pressure builds over the region.

Discussion As of 10:07 am pdt Saturday... Typical july cloud
pattern with widespread coastal clouds spreading across the inland
valleys. As of 10 am... Clouds have pretty much rolled back to the
immediate coast with mostly sunny skies inland. The visible
satellite also show a decent amount of mid to high level cumulus
clouds stream in from the se. These clouds are associated with
some lingering monsoonal moisture. Interesting item of note is the
oak sounding recorded a new daily record for precipitable water.

The new record value is 1.57". Simply put, there is a ton of
moisture in the mid and upper levels of the atmosphere. The
sounding also reveal over 500 j kg of mu cape, which explains some
of the cumulus clouds. However, the sounding also showed a decent
amount of cinh - over 300 j kg. Therefore, no convection is
expected. The latest hrrr did show a possible build up over the
terrain in san benito county. Will have to watch closely, but not
adding any precip storms to the forecast at this time.

The main potential weather impact over the next few days will be
the building heat across the interior, especially southern
monterey san benito counties. Issued a hazardous weather outlook
to address this potential. Will need to take a closer look to see
if a heat advisory is needed.

Prev discussion As of 3:18 am pdt Saturday... Current satellite
imagery is nearly a carbon copy of yesterday at this time with
coastal stratus extending into the bays and inland valleys. The
marine layer depth is currently 1600 feet per the fort ord
profiler and the surface pressure gradient remains onshore with
2.4 mb from sfo to sac. Expect high temperatures today to be
similar to those on Friday with 60s to mid 70s at the coast, to
the 70s and 80s inland, with warmest well-inland areas in the
lower to mid 90s. Similar conditions are expected on Sunday with
coastal stratus fog in the morning, clearing by afternoon.

High pressure is forecast to rebuild into southern california from
the desert southwest. This will usher in a warming trend for
california by the middle of the week with high temperatures once
again exceeding the century mark in the hottest well-inland
locations in southern monterey and san benito counties,
especially after midweek. Near-coastal locations are expected to
stay cooler thanks to a continued onshore flow. The hottest areas
will be farther to the east and south, closer to the ridge axis,
thus for now, no heat products are in effect. Heat advisories may
be needed as we get closer to the event.

Aviation As of 10:16 am pdt Saturday... For 18z tafs. Almost a
repeat of the last few mornings, all terminals have becomeVFR.

ExpectingVFR this afternoon with a few high clouds overhead. Some
gusty winds will be possible this afternoon with onshore flow.

Expect CIGS to move in again overnight with lower confidence for
ksfo and ksjc.

Vicinity of ksfo...VFR. Some patchy CIGS will likely develop again
around the terminal, but conf is too low to add to taf. Light
ne winds this morning increasing to westerly around 15 kt this
afternoon.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals...VFR through this afternoon. Low cigs
return early this evening.

Marine As of 10:07 am pdt Saturday... A weak disturbance will
continue to produce light to moderate winds over the coastal
waters this weekend. Northwesterly winds are then forecast to
increase through much of the coming week. Long period southerly
swell will arrive early next week.
