Synopsis High pressure building into the area will bring
clearing skies and dry conditions through the week. Temperatures
will warm well above seasonal normals by Tuesday and continue
through much of the work week.

Discussion High pressure continues to build into the area this
afternoon. North to northeast offshore flow helped to clear skies
this morning. Breezy northwest winds continue this afternoon,
especially along the coast. These will diminish slightly tonight
and will become northeast again overnight keeping skies mostly
clear. Some patchy fog is possible around humboldt bay, but
coverage should be limited and any that does form should quickly
dissipate in the morning. The coldest inland areas of trinity
county could see some frost, but currently am not confident in it,
so have have the forecast at 37 degrees for hayfork. This will
need to be watched tonight.

Inland temperatures are expected to warm back into the 90s on
Monday. At the coast clear skies and breezy conditions are
expected once again Monday afternoon. Temperatures will warm into
the middle to upper 60s along the coast.

Tuesday and Wednesday high pressure moves overhead. Inland
temperatures will be in the mid to upper 90s. The light offshore
flow is expected to continue to on Tuesday and Wednesday. This
will likely allow the coast to warm up. High temperatures in the
70s are likely along the coast with warmer temperatures a few
miles inland. Winds will diminish along the coast and only be
around 5 to 10 mph each afternoon.

The models are continue to bring an upper level low towards the
coast late in the week and into the weekend. This brings the
potential for stratus and possible some mid level clouds on
Friday or possibly as early as Thursday. Current models continue
to show some light rain on Saturday, so have introduced a slight
chance for rain into the forecast. Confidence remains low on this,
especially the timing of the potential precip. Amounts look
fairly light at this point. Mkk

Aviation Clear skies and breezy conditions will continue
through the evening. Gusts of 25 to 30kt are possible along the
coast this afternoon. Tonight offshore flow is expected to keep
most areas clear, but there could be some patchy ground fog in the
near coastal valleys. This should clear up quickly for Monday and
winds are expected to be somewhat lighter on Monday although gusts
to 20 kt are possible along the coast in the afternoon. Mkk

Marine Northerlies will continue to increase through this
evening, with gale force gusts over the outer waters and occasional
gale force gusts downwind from prominent capes and points. Adjusted
the gale warning for the S outer waters (zone pzz475) to end Monday
afternoon (a bit earlier than the previous forecast). Otherwise,
headlines and the overall forecast remain generally unchanged. The
strong northerlies decrease by Tuesday as the tight gradient shifts
nw. Winds will remain fairly light through the remainder of the
forecast period with the direction backing to SW by Friday
afternoon.

N short period wind waves will persist mid to late in the coming
week with heights gradually decreasing after Monday night. In
addition, a NW swell currently at a period of around 8 seconds will
continue through this evening. A very small, periodic SW swell at
around 16 seconds will continue through the period. Sec

Fire weather A warming and drying trend will commence tonight
and Monday as offshore flow increases. Gusty northeast and east
winds with low rh's are expected tonight over the exposed ridges
of zones 203 and 204. Have issued a red flag warning to further
highlight the potential significant offshore winds and low rh. The
worst conditions are expected to be tonight above 1,500 feet. The
nam shows a fairly big area of 20 to 25 kt winds at 850 mb in
eastern del norte county and western siskiyou county. Breezy
winds will continue through Monday with low rh. Monday night into
early Tuesday winds will start to diminish, but rh recoveries will
be lower than on Monday morning. Local areas of increased gusty
winds and low rh are expected on Monday and Monday night across
humboldt and trinity counties.

Above normal temperatures and low rh's are expected each day
through much of the week before a cooling trend arrives toward
the end of the week into next 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.
