Synopsis for the southern oregon coastal waters.. North winds will increase and seas will steepen today through Wednesday evening as high pressure rebuilds offshore and the thermal trough deepens over california. Warning level seas are expected to develop over a portion of the area south of cape sebastian Wednesday into Thursday. Northerly gales are possible south of cape blanco this weekend as cooler air pushes southeastward from the gulf of alaska.

234 am pdt Tue jun 27 2017

Discussion Current radar scans are showing that the
thunderstorm threat has dissipated completely. This signals the
switch in the overall pattern from a strong ridge and thermal
trough which brought us record or near record temperatures over
the weekend to a more typical end of june pattern.

Meanwhile, current satellite composite imagery is showing a
relatively strong marine layer occurring along the coast which has
already pushed into the umpqua basin past the umpqua divide into
josephine county. At this rate, the marine layer could bring some
clouds all the way to grants pass before the night concludes and
the marine layer breaks up and moves back out to sea this morning.

With this marine layer, extremely light drizzle will be possible
along the coast. At this point, the drizzle is not expected to
produce measurable precipitation. Tomorrow evening and overnight,
however, the marine layer will come back; and the NAM and GFS are
indicating that some more light drizzle will be possible across
the coast and coastal mountains. This drizzle, although light,
could produce measurable precipitation; and have introduced a 10%
chance for it in a swath from a few miles south of port orford
northeast to the douglas and lane county border.

Elsewhere around southern oregon and northern california, the
water vapor and infrared satellite imagery suggests that the
clouds have moved out of our area and clear skies remain. The
forecast today will include a slight chance for showers and
thunderstorms this afternoon across portions of siskiyou county.

The moisture profiles are expected to be somewhat less than they
were the last two days which could very well be the limiting
factor for the cascades and the siskiyous. As a result, have
dropped the mention of thunderstorms over the cascades and
siskiyous from the previous forecast. A few models want to
produce a few showers and storms in lake county. Although moisture
will be somewhat higher than over the cascades, the lifted
indices and instability look to be stronger over the cascades
instead of lake county and this may be the limiting factor there.

Have left the mention of showers and storms out of the forecast
from lake county for now.

Beyond tomorrow, the forecast calls for drier weather and normal
temperatures across the board as our next ridge builds into place.

Although this could allow for the next thermal trough to build,
models are showing relatively stable 850 millibar temperatures
and have kept the forecast quite similar to the previous forecast
with only slight changes with a slight favoring toward the gfs
here and there. -schaaf

Aviation 27 06z TAF cycle... Along the coast and into the
umpqua valley, expect MVFR ifr CIGS throughout the night, but
clearing toVFR is likely in the morning as the marine layer moves
offshore. Elsewhere,VFR conditions are expected with breezy
north winds occurring in the afternoon for the rogue valley and
the cascades eastward. -schaaf

Marine Updated 1000 pm Monday, 26 june 2017... South to
southwest winds and light seas will persist through tonight. The
thermal trough is expected to develop along the coast Tuesday and
strengthen into Wednesday. This will result in the return of gusty
north winds and steep to very steep wind driven seas. The
strongest winds and seas are forecast from CAPE blanco south,
where gales and very steep and hazardous seas are possible, but
all areas will experience at least small craft advisory level
seas. These conditions are likely to persist through the remainder
of the week. -sven

Fire weather Updated 130 pm Monday, 26 june 2017... Unstable
conditions will combine with an upper level disturbance moving in
from the west to generate isolated to scattered storms over much of
the forecast area this afternoon. Lightning amounts should be less
than yesterday as moisture is less and there should be a quick
decrease in storms from west to east as even drier air moves in and
solar heating is lost. Also of concern is the potential for erratic
and gusty winds near storms today. Gusts of 40 to 50 mph are
possible near thunderstorms this afternoon and evening, especially
for storms that develop east of the cascades. Outside of
thunderstorms, gusty general west winds and continued low humidity
may fan any new fire starts. A red flag warning continues for much
of modoc county due to expected wind gusts of 30 mph and humidity 15
percent or less.

Red flag warnings remain in effect for the potential of increased
initial attack activity. Tomorrow there is a slight chance for
thunderstorms over siskiyou county with some lingering instability
and midlevel moisture. The rest of the week should be quieter as
cooler and more stable conditions dominate. -cc sk
