Synopsis for the southern oregon coastal waters..Winds and seas will remain below advisory levels into Tuesday morning. The thermal trough will strengthen Tuesday afternoon and more so on Wednesday. This will bring stronger north winds and choppy wind driven seas back to the area, especially south of cape blanco. Winds may reach gale force Wednesday afternoon through Thursday night south of cape sebastian. The thermal trough will weaken Friday and winds and seas will diminish at that time, but small craft advisory winds and seas will persist south of cape blanco.

Discussion An upper trough off the pacnw coast will be nudging
inland today and this will produce an increasing onshore surface
pressure gradient over western oregon. This gradient, combined
with a well-mixed afternoon boundary layer and southwest 700
millibar winds around 30 kts will result in gusty afternoon winds
across many areas. In general, the airmass will be fairly dry, but
by later in the afternoon some mid level moisture should
contribute to a slight thunderstorm threat over northern klamath
and far eastern douglas counties. There has been a deck of mid
clouds dancing around the cascades from jackson county northward
earlier tonight but those have shifted north. Those clouds may be
signaling where the moisture will be of greatest for afternoon
thunderstorms. Threat area looks reasonable.

The upper trough swings through overnight with any evening
convection quickly dying off followed by dry and warming weather
wed-fri. Another short wave trough looks likely to pass through
just to the north around Friday night. Some breezy south winds
and perhaps a subtle thunderstorm threat could accompany this
trough as well. Currently the pops are not high enough in the
forecast grids to bring a mentionable thunder threat in the
forecast, but these could increase over time so keep this in mind
for the east side. Stavish

Aviation For the 23 06z tafs... MVFR and areas of ifr ceilings
will persist all night into Tuesday north of CAPE blanco, including
at north bend. Expect ifr lifr stratus fog to fill into areas south
of CAPE blanco, mainly south of gold beach after 07z. MVFR ceilings
will push farther inland into the umpqua basin Tuesday morning,
impacting roseburg. These should mostly dissipate by Tuesday
afternoon, but MVFR ceilings could linger at some beaches and around
north bend.

Over the remainder of the area...VFR conditions will persist
tonight through Tuesday, with the exception of isolated
thunderstorms late Tuesday afternoon evening mainly from the
cascades north of crater lake across highway 97 near
chemult crescent to around fort rock. Gusty breezes will
develop again Tuesday afternoon. Gusts of 20-25 kt will be common in
many locations, with gusts occasionally more than 30 kt in the
shasta valley, modoc county and east of the cascades. -spilde

Marine Updated 230 am pdt Tuesday 23 july 2019... Winds and seas
will remain below advisory levels into Tuesday morning. The thermal
trough will strengthen Tuesday afternoon and more so on Wednesday.

This will bring stronger north winds and choppy wind driven seas
back to the area, especially south of CAPE blanco. Winds may reach
gale force Wednesday afternoon through Thursday night south of cape
sebastian. The thermal trough will weaken Friday and winds and seas
will diminish at that time, but small craft advisory winds and seas
will persist south of CAPE blanco. Jrs

Fire weather Updated 300 am pdt Tuesday 23 july 2019... No
change to previous thinking this morning. Breezy afternoon on tap
for most areas. Driest air will be east of the cascades. High
confidence remains with critical winds and gusts in the warning
area within fire weather zones 624 and 285. Dry afternoon
humidity will continue through the week with not much else too
exciting. However, there is another trough passage to keep an eye
on later Friday. Stavish

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