Synopsis A cooling trend will continue today as an upper level
trough and deep marine layer impacts the region. Temperatures will
then rebound to near seasonal averages late in the week. Coastal
clouds will likely persist and penetrate inland each night.

Discussion As of 03:36 am pdt Tuesday... A 2,000+ foot marine
layer continues to result in widespread cloud cover over the
region this morning. Most inland valley locations and just about
all urban areas are now under a solid cloud deck with temperatures
holding in the 50s. Should see these clouds mix out over the
interior late this morning into the early with lingering cloud
possible near the coast. All of this is a result of a mid upper
level low center over idaho and associated trough stretched across
northern california. Thus, expecting additional cooling region-
wide today compared to yesterday with upper 50s to lower 60s at
the coast to 80s inland. Only a few of the warmest interior
locations will reach into the lower 90s this afternoon. Smoke in
the atmosphere from ongoing wildfires across the state will also
impact portions of the region again today, especially over the san
francisco bay area and locations northward.

Expect temperatures to rebound a bit by Wednesday and through late
week as the aforementioned trough lifts to the northeast. This will
allow for high pressure over the desert southwest to strengthen
slightly as well. However, a broad mid upper level trough is
forecast to linger over british columbia and prevent the ridge from
strengthening too much over our region. Thus, look for temperatures
to remain near seasonal averages through late week and potentially
even into the upcoming weekend. With this, do expect the marine
layer to hold steady around 1,500 feet or so through the forecast
period with night morning coastal clouds penetrating inland each
night.

At this time, medium range guidance as well as the cpc's 6-10 and 8-
14 day outlooks continue to show no significant changes in the upper
level pattern through the end of the month. Thus, look for near
normal temperatures to persist along with generally dry weather
conditions.

Aviation As of 4:53 am pdt Tuesday... Low clouds have
infiltrated well inland this morning under a deep 2700 ft marine
layer. Confidence is low with respect to clearing times as the
marine layer has deepened significantly overnight. Will likely
have to push back clearing times at some terminals. Also of
concern will be the smoke. The latest hrrr model run depicts smoke
across the bay area today which will lead to reduced slant range
and horizontal vsbys. Otherwise light winds will prevail through
the morning with moderate onshore flow expected through the
afternoon.

Vicinity of ksfo... Ifr CIGS will persist through the morning
hours. Stratus is expected to clear to the coast this afternoon
however confidence is low. There is a chance that this may be an
all day stratus event as the marine layer continues to deepen.

Smoke may reduced slant range and horizontal vsbys over area
terminals this week.

Sfo bridge approach... Moderate to poor slant range visibility for
the period. Otherwise similar to ksfo.

Monterey bay terminals... Ifr CIGS will persist through the morning
hours. Stratus is expected to clear to the coast around 18z this
morning however confidence is low. Any clearing this afternoon
may be short-lived with CIGS expected to return once again by 03z.

Smoke may reduced slant range and horizontal vsbys over area
terminals this week.

Marine As of 2:53 am pdt Tuesday... A weak pressure gradient
across the region will maintain generally light west to
northwesterly winds over the coastal waters through much of the
week. Winds will increase over the northern waters late in the
week and into the weekend.

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.
