Discussion A frost advisory and freeze warning are in effect
for the klamath basin early this morning... With a majority of the
east side valleys which have already had a killing freeze also
near or below freezing.

The main change to the forecast was to include a slight chance of
light rain this afternoon along the douglas county and coos
county coast as a shortwave trough moves south over the coastal
waters. A similar scenario is also expected for Monday afternoon
and evening, but have introduced just a 5 to 10% probability of
light rain for coos and douglas counties. This may be raised
pending support from another model run. Both of these disturbances
will bring an increase of mid and high level clouds for much of
the area... This afternoon and again Monday into early Tuesday.

Model agreement has been good and increased further with the 00z
gfs and ECMWF quite similar through Thursday.

A broad ridge currently over the eastern pacific ocean will be
the main driver of our weather through Thursday. High temperatures
will have a gradual, steady warming trend with a persistent
pattern of light to moderate night-time northeast winds at 5 to 15
mph. These winds will be strongest over the ridges of western
siskiyou, josephine, and curry counties. This will include
downslope warming at brookings with highs in the 70s through the
weekend, peaking around 80 on Tuesday and then nearly as warm on
Wednesday. Elsewhere, highs will trend to near normal by Sunday
with mid 70s to lower 80s in west side valleys and mid 60s on the
east side... Then above normal through the week with a peak in the
mid to upper 80s in west side valleys and near 80 on the east
side.

There is still a modest though impactful model difference
regarding the late week forecast. The ridge is expected to move
east to the rockies with a trough moving into the pacific
northwest. The GFS has trended slightly weaker and keeps rain
well north of our area. But, this should at least bring several
degrees of cooling and an onshore westerly flow next weekend.

Aviation 23 00z TAF cycle... Areas of ifr CIGS and ifr MVFR
visibilities in patchy fog are expected to develop tonight and early
Saturday morning west of the coastal ranges. Also isolated patchy
fog with MVFR visibilities and MVFR ifr CIGS is expected in the
umpqua valley late tonight and early Saturday morning. Brief patchy
fog and MVFR vis CIGS is possible in the lower rogue and illinois
valley but confidence is low on how much may develop. Fog is
expected to clear between 16-18z Saturday morning. Elsewhere,
generallyVFR conditions are expected through the next 24 hours.

Marine Updated 300 am pdt Saturday, 23 september 2017... Short
period northwest swell will gradually subside today while a thermal
trough maintains gusty north winds and steep seas south of cape
blanco. Winds and seas will peak each afternoon and evening through
the middle of next week, and small craft advisory conditions will
spread north Sunday to cover a broader area south of CAPE blanco.

North winds may increase even further late Tuesday afternoon into
Tuesday evening with strong north winds and a mix of steep to very
steep seas possible across a wider area, to include some areas north
of CAPE blanco. There is some potential for gales south of cape
blanco during this time period. North winds will diminish Wednesday
into Wednesday night. Sk cc

Fire weather Updated 300 am pdt Saturday, 23 september 2017... .

A warming and drying trend is expected through the middle of the
week. Temperatures are expected to peak, and humidity values are
expected to be at their lowest, around Thursday as the thermal
trough moves inland. Breezy and dry is a fair characterization of
the fire weather environment towards the coast south of CAPE blanco
and in western siskiyou county. Additionally, those favored north to
south oriented valleys like the umpqua and illinois, will see breezy
conditions during the afternoons. One thing we've noted when
perusing the data is that the high haines index never really gets
above 3 or 4, even when the thermal trough moves inland. This is
indicative of the changing of the seasons, and the lack of a very
dry air mass or the instability needed to create critical fire
weather conditions.

Looking further out, the mostly dry and warmer than normal
conditions should generally persist through week 2. This is
supported by the operational models, CPC outlooks, and cfsv2 model.
