Synopsis A warming and drying trend will begin today and continue
into the weekend. The next chance for rain will be Sunday across del
norte and northern humboldt county.

Discussion Rain showers have come to an end across northwest
california this morning as a deep upper level trough exits into the
great basin, leaving the north coast in broad northerly flow between
the departing trough and a stout ridge over the eastern pacific.

Skies have begun to clear out across the area, which has lead to
patchy ground fog development aided by ample residual low level
moisture stemming from the rainfall of the past few days.

Temperatures can be expected to run several degrees warmer across
the area today given more abundant sunshine and warming
temperatures aloft, however the warming trend will really begin to
ramp up on Friday as high pressure begins to build into the
region from the pacific. This will support generally warm and dry
conditions through Saturday night before the next trough and an
associated cold front approach the region on Sunday. This trough
should be a bit weaker than the systems of the past few days, with
rainfall looking to remain lighter and mainly confined to areas
from humboldt bay north to the or border. This will also
temporarily halt the warming trend before another ridge builds in
for the beginning of next week. Cb

Aviation An upper level trough is exiting the region while
increasing subsidence behind the trough will result in improving
conditions through the day. However areas of shallow moist air will
likely result in ifr lifr conditions around the coast and for the
interior valleys early this morning. Conditions should improve
across the board later today in response to a drier brisk n-nw
flow and daytime mixing.

Marine Northerly winds and steeper waves will increase today
as a low pressure trough moves into the great basin. Also, a mid
period NW swell near 10 ft will decay today. Small craft advisories
are in effect for all waters. Northerly winds and seas will ease up
slightly over the weekend, primarily north of CAPE mendocino, as
another trough moves toward the pacnw. Conditions will deteriorate
again after trough passage late Sunday into Monday.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory from 2
pm this afternoon to 3 am pdt Friday for pzz450-455.

Small craft advisory until 9 pm pdt Friday for pzz470.

Small craft advisory until 9 pm pdt Saturday for pzz475.

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.
