Short term A strong upper level ridge is over the region and a
closed low is positioned under the ridge well off the coast near
40n and 137w. At the surface, a thermal trough is centered
inland along the cascades. This thermal trough will persist over
the area through Thursday. With the surface thermal trough and
ridge remaining in place, expect another day of very warm
temperatures across inland areas. Along the coast areas of low
stratus and fog will continue tonight into tomorrow.

Models show good agreement that the upper low will gradually
moving near the southern oregon and northern california coast on
Thursday. Southerly mid level moisture will move into the area and
with daytime heating expect adequate instability and CAPE for
thunderstorms as well as showers to develop. A cap is expected to
inhibit convection until late afternoon when temperatures reach
peak heating. So, thunderstorms and showers are expected develop
starting in the late afternoon and into the evening. SPC indicates
the risk for severe storms over the area has lowered given that
instability is not sufficient. Any thunderstorms that develop may
bring gusty winds though, especially for storms near and in the
southern oregon cascades. Small hail is also possible. The area
for thunderstorms to develop is mainly from the western slopes of
the cascades eastward and from the siskiyous southeastward.

However, western locations in eastern douglas, eastern josephine
and jackson counties may see isolated thunderstorms late Thursday
afternoon and Thursday evening due to southeast transport winds
allowing storms to move into these areas.

Isolated to scattered showers area also expected to develop
across western portions of the area from the coast and coastal
mountains into the western valleys late Thursday. As the low nears
the coast, showers are expected to continue Thursday night then
increase beginning Friday morning across the area. Shower
coverage is expected to be greatest over the southern oregon
cascades and to the west Thursday night and Friday with more
isolated to scattered activity to the east. Given the upper level
dynamics and lingering weak instability, have kept a slight risk
for thunderstorms in the forecast on Thursday night for areas over
the southern oregon cascades into klamath county on Thursday
night.

Friday afternoon and evening, the low will become positioned along
the extreme southern oregon and northern california coast. This
will send additional moisture into the region and bring additional
showers to the area. Cool temperatures are also likely on Friday.

Models continue to show weak instability and CAPE over northern
california and from the cascades east. So have continued the
slight risk for thunderstorms on Friday for these areas. Strong
storms are not expected. Then, Friday night into Saturday,
numerous to widespread showers are likely across the area as the
low moves inland and becomes centered over the cwa.

Long term Saturday through Sunday night... The extended period
will continue the showery weather. The low pressure system will be
centered across oregon on Saturday and will slowly move eastward
through the weekend into next week. CAPE and lis are indicating that
a few thunderstorms will be possible during this time, particularly
for the cascades and east. The overall showers are not expected to
drop significant rain or snow amounts, but heavier rainfall will be
possible in any thunderstorms. Snow levels will be 4000 feet, but
accumulating snow should only pose minimal impact this weekend.

-schaaf
Monday through Wednesday night... The region will be on the back side
of the trough on Monday with residual low level moisture in a cool
to cold northerly flow. Very light lingering showers and mountain
snow showers Monday will be diminishing and mainly west and north of
the rogue valley. The next ridge will build in from the west Tuesday
into Wednesday with a strong warming and drying trend. -dw

Aviation 25 18z TAF cycle... Over the coastal waters and along
the coast... Ifr CIGS will clear to the coast very soon, but they
will persist over the coastal waters. The lower conditions will
return to the coast this evening with higher terrain becoming
obscured, clearing back to the coast by Thursday afternoon. Over
the umpqua basin...VFR conditions will prevail through this evening,
but ifr CIGS will spread inland late tonight at least as far as
krbg with higher terrain becoming obscured. The lower conditions
will clear toVFR by late Thursday morning. Over the remainder of
the area,VFR conditions will prevail through Thursday morning.

Marine Updated 230 pm pdt Wednesday 25 april 2018... Conditions
will be relatively calm through Friday with weak low pressure over
the waters. High pressure will build in from the west Saturday into
Sunday, and small craft conditions are possible Sunday night into
Monday as northwest swell builds.
