Synopsis Inland temperatures will continue to warm over the
next few days as a ridge of high pressure builds aloft. Weak
onshore flow will maintain a fair amount of marine influence
with coastal low clouds persisting each day. Isolated
thunderstorms may develop across the interior through much of the
upcoming week, especially for trinity county.

Discussion The summer-like pattern continues with warming
temperatures inland and a stubborn marine influence at the coast.

The upper level pattern doesn't change much until early next week
with the approach of an upper low. Forecast models continue to
show a high pressure ridge axis to the east, with warm
temperatures and isolated convection developing across portions of
the interior... And plenty of coastal low clouds. For Sunday and
memorial day, the tail end of an upper- level trough will begin to
approach the region from the northwest. A few vort maxes are seen
in the data (especially the gfs) crossing the region during peak
heating Sunday and more so on Monday. This, combined with a
favorably southeast to south low- level flow, may allow a few
storms to develop across the interior as convective temperatures
are breached. The best chance of seeing a storm or two would be
east of an orleans - willow creek - covelo line. But the most
robust storm development will likely occur over sisikou county and
across southern oregon. Soundings show mid- level lapse rates a
little above 7 deg. C km with a nearly super- adiabatic low- level
environment. Freezing levels near ten thousand feet will make
some hail a possibility if these storms develop, with gusty winds
also possible given the inverted-v signature seen in the
forecasts. Any storm will be slow moving though given the weak
wind fields throughout the column, with storms likely being
terrain anchored or outflow dominant. Tuesday and Wednesday has
become more interesting, as the GFS drops the base of the trough
across the outer waters now, with a low in the base nearby. Strong
vort maxes ejecting across the region ahead of the low could aid
in convective potential if this forecast verifies. The ECMWF shows
a similar, albeit weaker solution. An increased extent of cloud
cover on Tuesday may inhibit vertical growth and may just end up
being a rainy showery cooler day. In any event, confidence in
potential foci for convection has increased, with increased
spatial and temporal periods for such added to the zones. By
Wednesday flow becomes a little more zonal but at this point
cannot rule out a continued threat of some convective activity as
it passes by to the north. Pd jt

Aviation Marine influence continues along and near the coast
in the form of a low stratus deck. Coastal terminals can expect ifr
conditions during the night and morning hours before CIGS rise in
the late morning hours and mixing begins in the early afternoon.

This pattern should continue to improve as the marine layer begins
to be suppressed as ridging builds over the area through the
weekend. Interior sites should remainVFR except the coastal valleys
where some stratus may creep in from the west and fill the valleys
during the late night and early morning hours.

Marine The period of light winds is expected to continue through
he weekend over the coastal waters as the upper level trough
continues to move over the area. A short period locally generated
north waves will develop again Monday through Tuesday as the north
wind increases. Generally favorable marine conditions are expected
to persist through at least Wednesday next week as the winds and
waves remain moderate.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... None.

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.
