Synopsis High pressure will result in dry and warm afternoons
accompanied by chilly nights persisting into the weekend across
the interior. Meanwhile, periods of low clouds and cool temperatures
are expected along the coast. A weak front will bring a chance of
light rain late Tuesday.

Discussion A blocking upper level pattern, with a ridge over
the pacific northwest and a trough over california, will slowly
break down and transition eastward this weekend. Sensible weather
will not change much over the weekend, with generally warm
afternoons and chilly early mornings expected for the interior.

A shallow marine layer, around 1000 to 1500 ft deep, will persist
near the coastline today. Early morning satellite imagery showed
an expansive low cloud deck offshore. This is not a good sign
for substantial clearing along the coast. Expect stratus to burn
back to the shoreline this afternoon, then advance back onto the
coast and into the adjacent river valleys again this afternoon and
evening. The stratus forecast has been based largely on persistence
for the weekend.

Dry weather will likely persist across NW california on Monday. A
weak front will approach on Tuesday and may bring light rain to
the area by Tuesday night. The best chances for light rain appear
to be in del norte and northern humboldt counties. Models indicate
moist westerly flow and additional perturbations moving over the
top of a northeastern pacific ridge mid to late next week. We may
receive another bout of rain mid to late next week. The timing
appears to be centered on Thursday, though it could speed up and
arrive as early as Wednesday night. Conditions should start to dry
out on Friday as the offshore ridge amplifies over the forecast
area.

Aviation Stratus continues over the coastal waters of NW ca and
extends inland up the adjacent valleys. Inland stratus penetration
and the acv profiler indicate that the marine layer is about 1500
feet thick. Low clouds are forecast to erode from the land side with
daytime heating, scattering out by afternoon along the redwood coast.

Low clouds are expected to expand once again this evening. However,
models are indicating that some drier offshore flow may develop
after midnight Saturday morning, with improving conditions prior to
sunrise. Kuki is expected to remainVFR through the period. Winds
across the area will be light. Sec

Marine N winds will increase a bit over the area today, with
the strongest winds in the NW corner of zone 470. This will be
enough to generate some marginal small craft advisory seas in the
outer waters from around mid-afternoon today through mid-morning
Saturday. W-nw swell at around a 13 second period will persist
into early next week, with a fresh batch of NW well arriving
thereafter. Longer period SW swell will continue through much of
the forecast cycle as well. Sec

Fire weather Issued 338 pm pdt Thu oct 18 2018. Warm
temperatures and low humidity values will persist across the
interior through the weekend. Winds will be largely light and
terrain-driven, but will tend east- northeasterly over the exposed
ridges and upper slopes in the thermal belt. This will be
especially true Friday night into Saturday morning, with some
local gusts up to 25 mph. Do not anticipate red flag conditions,
but will headline in the fwf. In the extended range, rain chances
will increase later Tuesday, especially north of mendocino county.

Eka watches warnings advisories
Ca... Frost advisory until 9 am pdt this morning for caz102-104-106-
110-111.

Northwest california coastal waters... Small craft advisory from 3
pm this afternoon to 9 am pdt Saturday for pzz470-475.

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.
