Synopsis Warming trend for NW california through next week,
with above normal temperatures and dry conditions expected for the
next seven days.

Discussion A chilly start to your Saturday
morning, but not as cold as Friday morning. Some areas in trinity
county and interior mendocino county saw temperatures dropped into
the mid 30s overnight. Hayfork is the cold spot, with overnight lows
in the low 30s. The frost advisory would be in effect through 8 am
this morning for those areas. With abundant sunshine today,
temperatures will rise to near 80 degrees for interior locations, in
the 60s for coastal locations.

The big weather story for the next week will be warming trend and
persistent dry weather. Currently, there is a broad large scale
trough set up shop over the western us. This trough will be taking
its time moving to the east. NW california will be on the western
side of this upper level trough, so we will see northerly upper
level flow. This means that we will be seeing an elongated period of
dry weather. As the trough shifts to the east, the height will rise
and we will see a warming trend through middle of next week. Do
expect above normal temperatures to persist through the end of the
work week.

Aviation High pressure building into the area will continue to
bring mainly clear skies andVFR conditions. A few local areas of
patchy fog are possible along the coast in the morning, but these
should be limited in coverage and duration. Breezy northwest winds
are expected along the coast in the afternoon and early evening. Mkk

Marine High pressure building in has increased the northerly
winds, mainly over the outer waters this morning. Yesterday
evening's ascat pass showed winds of 20 to 30 kt across much of the
outer waters. Seas at the buoys remain around 7 to 10 feet.

This afternoon and evening these stronger winds will push closer to
the coast. So have extended the small craft advisory for the
northern inner waters through late this evening and added one for
the southern inner waters for this evening.

Winds and seas will remain elevated through Tuesday with high
pressure in place. Widespread gales are not expected, although
occasional gale force gusts are possible here and there. Tuesday
night into Wednesday winds will diminish rapidly as an upper level
low drops into the desert southwest and disrupts the pressure
gradient. Winds are expected to remain light through the end of the
work week. There may be some light southerly winds in this period,
but models are struggling on the details of this. Next weekend
northerly winds are expected to return.

No significant swells are expected through the week, although the
northwest swell is expected to linger around 3 or 4 feet at 10 to 12
seconds. Mkk

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.
