Synopsis Light rain will taper off across portions of del norte
county this evening. Otherwise, mild and dry conditions are expected
to prevail across the region through early next week.

Discussion A weak upper level disturbance moving through the top
of the NE pacific ridge has been sufficient to generate a few
sprinkles over del norte county today, however the primary impact
for most of the area has been an increase in cloud cover helping
to hold afternoon high temperatures down in the low to mid 50s.

The exception has been farther south into mendocino county where
sunnier skies and slightly warmer temperatures prevail. Any light
rain will quickly come to an end this evening as the upper wave
drops south through the area. The ridge will then continue to
amplify during the end of the work week as the ridge axis nudges
eastward to the coast, promoting mostly clear skies and slightly
warmer daytime temperatures heading into the weekend. The
combination of clear skies and large scale subsidence will
continue to support potential fog formation in the typically
favored areas for the next several nights. A potent shortwave
trough progged to dig southward across the intermountain west
early next week will bring more robust offshore flow and colder
temperatures aloft to the area, however sensible weather impacts
look to be negligible as high pressure continues to dominate the
ne pacific and west coast for the foreseeable future. Cb

Aviation MVFR ceilings have spread into acv and cec as a weak
storm system arrives from the northwest. Some light drizzle will be
possible late this afternoon and evening at both sites, with some
improvement in ceilings and visibility expected after midnight,
followed byVFR conditions during the day Thursday.

At uki, some patchy shallow fog will be possible overnight tonight,
but any that manages to develop should dissipate by late morning.

Confidence is low regarding this. Brc

Marine Very little change is expected through the end of the week
as the waters will remain within a regime of moderate to fresh
northerlies. As is often the case in northerly flow regimes, the
strongest winds are expected to occur from CAPE mendocino
southwards, where winds of between 15 and 25 kt are expected to
generate some moderately steep seas. Otherwise, ocean conditions
will generally remain dominated by a series of long period westerly
swells, the first of which will continue to build through the
evening today. While small in comparison to some of the larger
swells we've seen this season, these swells will likely bring
significant wave heights to near and even slightly above 10 feet,
and while seas have not quite reached these heights as of 2 pm
Wednesday, small craft advisories will be allowed to continue
given the expected upward trend later today.

Winds are expected to weaken later in the weekend and early next
week, and eventually turn primarily offshore easterly. Meanwhile,
moderate westerly swells will continue to move through the
waters. Brc

Beach hazards A series of moderate long period westerly
swells will impact area beaches this week, which may result in an
elevated risk of sneaker waves at various times. Beachgoers are
urged to use caution on area beaches, and maintain a safe distance
from the surf line at all times. Brc

Eka watches warnings advisories

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
