Short term Today through Saturday... The warming and drying trend
has begun. Current temperatures are 10 to 15 degrees warmer than
24 hours ago, and observed precipitation today is only spotty and
generally just a few hundredths of an inch. Showers are focused
east of the cascades, closer to the upper low that's departed to
the east and is currently over southern nevada. One lightning
strikes has been observed over eastern siskiyou county, but we
don't expect much in the way of lightning because instability is
limited. Winds are gusting to 25 mph in much of the forecast area
this afternoon. Winds should diminish this evening and become
gusty again tomorrow. High resolution model output brings a chance
of showers this evening to some west side valleys as showers over
the cascades are transported southwest by deep north-northeast
flow. In addition, stable low clouds along the coast will shift
inland overnight and could bring some light drizzle to coast and
coastal valleys.

Tomorrow, some additional warming and drying is expected as the
exiting low loses influence over the forecast area. Still, there is
a slight chance of showers along and east of the cascades Thursday
afternoon. Given that we've had a lightning strike today, and we
expect similar to slightly more unstable conditions over the
cascades tomorrow, we've kept a slight chance of thunderstorms over
the cascades Thursday afternoon.

On Friday we'll begin to feel in the influence of an approaching
upper low moving south from washington. The first areas affected
will be east of the cascades with increasing chances for showers
there. East of the cascades looks dry on Friday. Models suggest more
of the same Saturday afternoon, though shower chances creep into
areas west of the cascades late Saturday as the low moves overhead.

With all that said, there is a surprising amount of spread amongst
ensemble members in terms of where the upper low center will be
Saturday afternoon. Therefore, we maintain low confidence
for Saturday's precipitation forecast. Our current forecast reflects
the national blend of models (nbm) solution but is subject to change
as ensemble members start to agree more on the evolution of the
low. Keene

Long term Sunday through Wednesday... Not much has
changed with the overall pattern through the holiday weekend.

General troughing will remain over the area which means we could be
dealing with a chance of showers and afternoon and early evening
thunderstorms Sunday through memorial day for most inland locations.

There's been fairly good agreement among the models the past couple
of runs. However the latest ECMWF now shows a stronger upper low
moving south along the oregon coast and has enough over water
trajectory to produce a significant amount of moisture for this time
of the year on Sunday. The GFS and canadian have stayed the course
and show a weaker upper low near or over the area which would result
in a fair amount of dry time in the morning, especially west of the
cascades followed by increasing showers in the afternoon with
isolated thunderstorms possible. It remains to be seen if the latest
ecmwf solution is a one hit wonder or will it revert back to a
solution that's more in line with the GFS canadian. For this reason
and high spread among some of the ensemble members, have decided not
to increase pops much on Sunday, but watch for updates on this
should future runs continue to show the wetter solution.

The upper low is expected to set up southeast of our area Monday and
there is concern we could be caught up in some wraparound moisture.

It this turns out to be the case, then we'll have a higher chance
for showers pretty much all day with the highest chance for showers
in the afternoon and evening. The individual ensemble members show a
pretty good spread with the location of the upper low. Confidence is
higher we'll have frequent showers east of the cascades, but lower
for shower coverage west of the cascades, especially Monday morning.

The upper should finally move far enough away where we could end up
with drier and milder conditions next Tuesday. Wednesday also looks
mostly dry and milder, although isolated showers are possible in the
afternoon east of the cascades. -petrucelli

Aviation Updated 200 pm pdt Wednesday 22 may 2019... Offshore high
pressure coastal thermal trough pattern will continue to strengthen
through tonight, producing gusty north winds with steep to very
steep wind-driven and fresh swell dominated seas. Winds will
approach, but are not expected to exceed, gale force south of gold
beach this afternoon and evening and again Thursday afternoon and
evening. Seas will be very steep and hazardous over a larger area
from around CAPE blanco south and beyond 5 nm of the coast. The
thermal trough will move inland over the weekend, and winds and seas
should gradually diminish, although guidance suggests that
strong north winds could return by the middle of next week. -bpn

Marine For the 22 18z tafs... From the cascades west... CIGS have
been a mix of MVFR andVFR this morning and this is expected to
continue into the morning and afternoon. Isolated showers and
mountain obscuration will occur for the majority of the day. Tonight
ceilings will lower to MVFR or ifr in most valleys west of the
cascades.

East of the cascades... Areas of MVFR CIGS with higher terrain
obscured will clear toVFR by this afternoon with gusty north winds
and increased turbulence. These conditions will persist into this
evening. There will also be isolated showers east of the cascades
throughout the day. Tonight the lowest conditions will occur on
north facing slopes due to northerly wind pushing lower clouds
into these areas. Keene
