Synopsis for the southern oregon coastal waters..High pressure remains offshore but a weakening thermal trough along the coast will result in lesser wind and lower seas today versus Sunday, especially south of cape blanco. Then, conditions remain fairly consistent through Wednesday. A cold front moves through late Wednesday followed by a strengthening thermal trough Thursday and Friday.

Update Updates to marine, aviation, and fire discussions. Ms

Discussion The sky condition varies across the area with low
clouds at the coast roughly from CAPE blanco northward and into
the coquille valley, a band of high clouds over south central
oregon and northern california, and variable thickness of wildfire
smoke. The low clouds should thin at least partially before this
morning's solar eclipse reaches its maximum obscuration at 1015 am
at north bend. The high clouds are also expected to thin somewhat
this morning. Smoke is thinnest over lake, modoc, coos, and
western douglas counties. Other times of maximum obscuration
include 1017 am along the i-5 corridor, 1018 am at klamath falls,
and 1020 am at lakeview. After the eclipse, mid and high level
clouds are expected to increase over northern california as a
closed low offshore from southern california spreads increasing
mid-level moisture northward.

Northeast winds at the coast have weakened substantially tonight
compared to last night but they will continue until around 9 am
before a switch to light northwest winds brings a welcome
increase of humidity during the day to the brookings area. While
multiple complexes of wildfires continue in our area, there is a
risk of new fire starts due to lightning Tuesday afternoon through
Wednesday evening. A fire weather watch pdxrfwmfr has been
issued with continued very good model agreement in the highest
risk during Tuesday afternoon and evening. A slight chance to
chance of thunderstorms is forecast roughly from the cascade and
siskiyou mountains of southwest oregon eastward and southward.

Southwest to west steering flow is likely to bring a slightly
higher risk to siskiyou county and southern klamath county compared
to the remainder of the aforementioned area. Storms will be
relatively slow moving at around 5 to 15 mph.

The risk of thunderstorms will diminish but not altogether end
late Tuesday night with the possibility of embedded shortwaves
continuing convection.

The scenario for Wednesday will be a bit different and leads to
diminished confidence in the forecast. A trough approaching
british columbia will bring a stronger southwest to west 700 mb
steering flow of 10 to 20 mph and also the possibility of a focus
for thunderstorms east of our area... In eastern oregon. The
probability of thunderstorms in our area will be higher east of
the cascades. The approach of the trough and an associated cold
front will bring gusty afternoon westerly winds... Strongest on the
east side. A slight chance of late night and early Thursday
morning drizzle or very light showers exists for coos and western
douglas counties with the push inland of a relatively deep marine
layer.

The trough will push into the pacific northwest on Thursday and
bring a stable air mass into the region. High pressure building
will bring a strong warming and drying trend Friday through the
weekend into early next week. -dw\

Aviation 21 12z TAF cycle... High pressure prevails with primarily
vfr conditions over the region. Ifr CIGS and visibility in fog along
the coast will erode some but may last all day in some areas as an
onshore wind prevails in the afternoon. Inland,VFR weather will be
the rule except for possible ifr vsby in smoke. Upper flow
transition to south today presents different possibilities versus
Sunday. SomeVFR vsby in smoke is again possible at kmfr and perhaps
later afternoon at klmt, but uncertainty is considerable. Stavish

Marine Weaker northerlies on tap today as thermal trough has
weakened and will shift inland this afternoon. Remaining hazardous
seas for a while however. Similar winds Tuesday and Wednesday but
lower seas. Thermal trough strengthens for Thursday and Friday with
north gales looking likely. Stavish

Fire weather Thermal trough shifting inland today normally
signals the hottest inland day of the stretch and expect
temperatures to be up several degrees where smoke isn't a limiting
factor. Broad onshore gradient in the late day will produce
west to northwest flow all west side areas with gustiness peaking
5-6pm. Haines 4-5 also signals good atmospheric support for active
fire development. Historically, inland fires have become more
active as the thermal trough moves inland from the coast.

Thunderstorm chances look appreciable Tuesday afternoon and night
and fire weather watch for lal3 coverage has been issued. Zones
622 and 617 have minimal areas in the watch. Higher pw arriving
suggest west storms but the transition should produce a mix of wet
and dry. Storm wetness not a factor in watch warning decisions
here however, just lal fuels. Look for increased gustiness
Wednesday as upper trough approaches from the northwest and cold
front pushes through. With drier air arriving from the west, this
potential storm trigger may not produce as many storms as
previously envisioned on wed. Stavish
