Synopsis Hot and dry weather will generally prevail across
northwest california through the weekend, with inland temperatures
warming 10 to 20 degrees above normal today. A slight chance of
showers and thunderstorms exists Sunday afternoon and evening over
trinity and mendocino counties.

Discussion Hot temperatures will persist through Saturday with
triple digit heat expected in many of the interior valleys. Offshore
flow will also aid in warm temperatures over the northern half of
coastal del norte county. The inherited heat advisory includes
that potential... Thus no changes were made to the headline. The
offshore flow is also supporting locally gusty ridge top
winds and a slightly elevated fire weather threat. A headline
continues to address these conditions in the fire weather
forecast.

Marine stratus is forecast to aggressively spread north along the
coast Saturday and Sunday, and could be accompanied by drizzle.

Otherwise, model guidance shows an upper ridge beginning to break
down over the wrn CONUS during Sunday as a minor impulse,
accompanied by slightly cooler midlevel temperatures, spreads
north downstream from a nern pacific trough. This impulse will
aid in shower and thunderstorm development over portions of
mendocino and trinity counties Sunday afternoon evening.

Thereafter, the ridge further deamplifies on Monday as the trough
located offshore moves inland. However, the environment during
Monday is forecast to be too dry for the development of
showers thunderstorms.

Aviation Winds have continued to remain gusty at kcec
overnight and into the early morning hours, and the latest model
guidance suggests this trend will continue into the late evening
tonight, before calming down for Friday morning. Here, wind gusts
in the 25 to 30 knot range will persist.

Moving on down the redwood coast, things have been relatively
quiet at kacv, with light winds and just some localized stratus
occasionally playing tag with the airfield. This looks to continue
through sunrise, and we opted to carry a scattered cloud group at
1200 feet to cover this. Should any MVFR ceilings develop, it
looks to be marginal enough both a spatial and temporal standpoint
to preclude inclusion in the tafs for now.

Finally, look for great flight conditions to continue at kuki,
where conditions will remainVFR with calm winds becoming light
and variable during the afternoon. Pd

Marine We're starting to round the corner somewhat as far as
the winds and waves are concerned. Although a few gusts near storm
force remain possible across the western half of our northern
outer waters, by in large, look for sustained gales to continue
for both the northern and southern outer waters through Friday.

Waves will generally be in the 14 to 18 foot range, with a period
around 10 or 11 seconds.

For the inner waters, small craft conditions will continue with
sustained winds near 20 knots and gusts to near 30 knots, with waves
running in the 10 to 15 foot range. Here, a similar wave period
of 10 or 11 seconds is expected. Conditions will gradually improve
from south to north for the inner and outer waters during the day
Friday. Pd

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.
