Synopsis Hot afternoon interior temperatures will occur through
Thursday... While the coast sees a return of the marine layer
influence. Cooler weather with scattered showers will then
spread across the area this weekend.

Discussion Offshore flow continues to diminish across the
region in terms of wind speed's. This flow regime is favoring
very warm and dry conditions that will support hot afternoon
temperatures as well as fire weather concerns due to a pool of
very dry air above about 2000 ft in elevation. Hot inland
temperatures will continue through Thursday, with highs in the 90s
expected across most of the interior, ranging to 70s along the
coast. Coastal locations will begin to see a return of the marine
influence as stratus surges up the coast. An upper low positioned
well offshore this morning is forecast to drift eastward through
Friday as an upper high shifts northward. By Saturday, model
guidance shows the upper low moving onshore, though large
positional differences exist between various deterministic
solutions. Nevertheless, showers and cooler temperatures appear
probable during Saturday, and thunderstorms can't be ruled out if
the GFS verifies. Thereafter, the ECMWF maintains a showery regime
going into next week, while the GFS favors a dry environment.

Aviation Mostly clear skies andVFR conditions prevailed across the region
today with a few exceptions: stratus continued to surge up the
mendocino coast to just south of CAPE mendocino until 10 am... Then
stratus rounded the cape. By 1 pm clouds had approached humboldt bay.

The other exception was wildfire smoke in del norte that advected
west to cec through mid-late morning, bringing MVFR-ifr cig vis to
the airport. Smoke (fu) CIGS continued into afternoon becomingVFR.

Therefore, the afternoon's 24 hour outlook for the coastal stations
will be continued smoke at cec. Stratus may reach the acv airport at
least briefly in the mid-late afternoon. However, offshore flow may
not weaken until Wednesday... Hindering widespread stratus north of
humboldt bay tonight. Inland areas will remainVFR, although local
stratus could possibly move northward to the mendocino sonoma county
line. Ta

Marine Northerly winds will continue to diminish as we go
through the day. The one exception will be across the northwest
potion of the northern outer waters where near gale force gusts
and small craft seas will remain through this evening. The winds
will remain fairly light through the remainder of the forecast
period with winds becoming southerly late this week. A periodic sw
swell at around 16 seconds will move through the waters beginning
later today and persisting through this weekend. Wci jt

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
