Discussion A warming and drying trend started today and is
expected to continue through most of next week. At the
coast the thermal trough is expected to build to around cape
blanco with dry offshore flow for curry county. However to the
north it will be mainly onshore flow into coos and douglas
counties and low clouds can be expected with occasional drizzle at
night along the immediate coast. Inland temperatures will
approach season normal Sunday and Monday, then rise 5 to 10
degrees above normal Tuesday and Wednesday as the thermal trough
shifts inland.

The ridge is expected to shift east Thursday. Both the ECMWF and
gfs are consistent on this feature and bring a weak cold front
inland around Thursday night. Aside from increasing low clouds and
drizzle at the coast, this front is expected to be dry elsewhere
but with an uptick in west to southwest winds. The cooler air mass
behind this front will only be enough to bring high temperatures
to seasonal norms, but could bring much cooler overnight low
temperatures next weekend. Fb

Aviation 24 18z TAF cycle... Patchy ifr to lifr fog and low
ceilings are beginning to clear along and near the coast north of
cape blanco, but should make a return this evening and tonight.

Elsewhere,VFR will prevail. -bpn

Marine Updated 230 pm pdt Sunday, 24 september 2017... High
pressure offshore and a thermal trough along the coast will maintain
gusty north winds and steep from CAPE blanco south through Tuesday.

Winds and seas will peak each afternoon and evening today through
Tuesday. North winds may increase further and peak late Tuesday
afternoon into Tuesday evening with gusts to 35 kt possible for
areas south of gold beach. These increased winds may bring a mix of
steep to very steep seas to the waters with very steep seas possible
mainly beyond 10 nm from shore south of gold beach. Additionally,
steep seas and small craft advisory winds and seas may expand north
of CAPE blanco in the late afternoon and evening on Tuesday. Gusty
north winds will diminish late Wednesday morning but steep seas may
linger through late Wednesday afternoon. On Thursday, light
southerly winds and light seas are expected across the waters. -cc

Fire weather Updated 200 pm pdt Sunday, 24 september 2017... .

A warming and drying trend is expected over the next several days,
with breezy north winds in the afternoon, and light east winds
overnight. Of note is the recent GFS model trend showing a solidly
dry air mass Wednesday through Friday, to include potential for poor
to moderate humidity recoveries each night during that period.

Temperatures are expected to peak, and humidity values are expected
to be at their lowest, around Thursday as the thermal trough moves
inland. With dry and unstable conditions expected by that point, if
there is a period of time where fire activity picks up, then that
would be it.

At no time during the next week do we expect critical fire weather
conditions. There will be periods of breezy and dry conditions, but
winds and humidity aren't expected to align enough to warrant any
fire weather watches or red flag warnings.

Looking further out and considering the past several days of model
data, the mostly dry and warmer than normal conditions should
generally persist into week 2. However, there are very recent trends
in the long range models that suggest some wetting rains are
possible roughly beyond day 10. Bpn

Mfr watches warnings advisories
Or... None.

Ca... None.

Pacific coastal waters... Small craft advisory until 5 am pdt Wednesday for pzz356-376.

Hazardous seas watch from Tuesday afternoon through late Tuesday
night for pzz376.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
