Synopsis Hot and dry conditions will continue today, followed
by a cooler pattern during the remainder of the week. Otherwise,
smokey conditions will persist across mainly in the interior areas
of the region through the work week.

Discussion A weak upper level trough has moved over the pacific
northwest. This has brought a deeper marine layer and inland
temperatures may cool by a degree or two today. This has also
brought fairly extensive stratus to the coastal areas. Tonight
into Tuesday this moves to the south over the area as an inside
slider type system. Model sounding profiles show conditions fairly
dry and the dynamics look to mainly through in the morning. The
lapse rates above 600 mb are quite poor. So have removed the
slight chance for thunderstorms over interior del norte county.

More significant cooling is expected across the interior as the
trough sets up over the west coast.

Wednesday through Friday a fairly weak upper low flow pattern sets
up over the area. This should bring near normal temperatures which
will be cooler than what we have been seeing. Temperatures will be
around 90 in the inland areas. Stratus is expected to be fairly
widespread in this pattern with a fairly deep marine layer.

For the weekend the upper level trough continues to deepen over
the area. This will continue to cool off inland temperatures. At
the coast stratus and drizzle is expected. Early next week there
is the potential for some light rain as the upper level low tries
to cut off and move onshore. For now confidence is very low on
this, although have added a slight chance for showers on Monday.

Aviation Stratus has been covering the north coast and adjacent
river valleys through the night. The layer appeared to be slightly
deeper early this morning with ceilings around 500 feet as of 4am.

Ceilings should continue to fall by daybreak with perhaps brief vsby
obscuration due to mist. Ifr conditions this morning are expected to
improve toVFR this afternoon. Stratus will most likely redevelop by
mid to late this evening with ifr conditions expected to last
through the morning hours on Tuesday at both kcec and kacv. Also,
smoke from nearby wild fires may briefly impact kuki with MVFR or
ifr conditions by mid to late morning. Otherwise,VFR conditions are
expected to prevail at kuki through the forecast period.

Marine Brisk northerly winds and steep hazardous seas will
continue across the outer waters today. For the inner waters, winds
will generally be lighter except around and downwind of cape
mendocino. In any case, seas will be rough and uncomfortable across
the inner waters. Winds and seas will ease up Tue and Wed as broad
low pressure develops over the area. North winds and steep wind
waves will increase Thu through fri.

Fire weather Nocturnal offshore flow is expected to continue
through Monday night across interior del norte county. Gusts to 25
mph are possible along the ridge tops. Otherwise, hot and dry
conditions, with temperatures in the 90s, will continue through
Monday. Temperatures will start to cool on Tuesday and the marine
layer is expected to deepen. The rh recoveries will improve
overnight as well.

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.
