Synopsis Temperatures will cool slightly throughout the week as
an upper-level trough impacts the area. Otherwise, smoke will
persist across most of the area through the work week.

Discussion An upper-level trough continues to churn over the
northern great basin, which is aiding in cooler temperatures
across the interior. As the trough exits the region, another
disturbance is forecast to move through the western u.S. Thursday
night. Temperatures will continue to be seasonable through the
rest of the week as the the first trough exits and the second
trough enters the area. Highs should be in the mid 80s to low 90s
across the interior and 60s along the coast.

Near the coast, stratus will be likely during the night, followed
by partial afternoon clearing. Stratus may form near ukiah as
well. Otherwise, current visible satellite imagery shows smoke
continuing to drift south from wildfires in british columbia,
washington, and oregon. This area of smoke is forecast to linger
across the CWA through mid to late week.

Aviation A sustained marine layer continued along the north
coast and into nearby coastal locations today. The ongoing result
has been an enveloping stratus layer extending from 100 feet to
an average top of 1500 feet. By early afternoon, CIGS had somewhat
lifted but remained ifr lifr as onshore flow kept clouds (as seen
on satellite) pushed up along coast, therefore limiting probable
clearing at the coastal terminals. Similar conditions expected to
continued into Wednesday. Inland areas continued to be inundated
with widespread smoke due to wildfires. The smoke has impacted
local airfields with various degrees of lower vis and cig. No
change is expected through Wednesday. Ta

Marine Northerly winds and seas continue to decrease today. Light
to moderate southerly to southwesterly winds have developed along
the entire coast this afternoon and will spread across all of the
waters by tomorrow. These conditions will persist until Thursday
when north winds and steep wind waves will increase with small craft
conditions possible by late Thursday night across the outer waters.

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.
