Updated aviation discussion
Discussion Current satellite is indicating a widespread marine
layer pushing across the entirety of coos county, northern curry
county, and filling into douglas county from the coast and
from the north. Expect this marine layer to make it to roseburg
by daybreak. Meanwhile, some marine fog and stratus are building
in from brookings and moving both north and south off the coast.

It remains to be seen if the push will move onto the coast, but it
wouldn't surprise me in the slightest. The rest of southern oregon
and northern california continue to experience clear skies.

The thermal trough has weakened a bit, but our overall area of
high pressure remains over the area. Our warm and dry weather
pattern will continue through Tuesday before a front moves over
the area. Models have come into great agreement regarding this
frontal system, so have blended them, and introduced at least a
slight chance for precipitation across the entirety of the west
side, with the better chances of measureable precipitation
occurring at the coast and along the coastal range. The other
major change to the forecast was to drop high temperatures on
Wednesday. We no longer look like we're going to get into the
upper 80s to mid 90s with this system. Model guidance is showing
considerable lower temperatures (down to the mid 70s west side and
upper 60s to low 70s east side). Have trended the forecast down to
better match guidance. That being said, we're still on the high
end of guidance, and further trending may be needed.

Have taken a look at thunderstorm parameters, and they don't seem
to really be lining up for this event. This means that this front
is more typically like what one might see in the mid to late fall,
rather than late summer. That being said, we aren't expecting
thunderstorms, but we are also not expecting wetting rains. Still,
any precipitation can help keep our fire season rather light (as
compared to previous years).

After this front moves through, the area of high pressure returns,
and we return to a more typical august warm and dry pattern with
light breezy winds in the afternoons. -schaaf

Aviation For the 19 12z tafs... Along the coast and just
inland... A deep marine layer has resulted in MVFR ceilings and these
will continue through early afternoon then clear toVFR. MVFR
conditions are expected to return this evening and possibly lower to
ifr early Tuesday morning. Further inland over the umpqua basin near
krbg, MVFR ceilings should continue through mid to late morning
before clearing toVFR. Ceilings are less likely to return tonight
as the marine layer is expected to compress some. Elsewhere,VFR
conditions will continue through the TAF period. Keene

Marine Updated 230 am pdt Monday 19 august 2019... Mostly light
winds and low seas will prevail over the waters through Tuesday
morning. A cold front will bring a period of increasing south
winds Tuesday afternoon into Wednesday with building swells late
Tuesday night through Thursday. Latest model data suggests
southerly winds and mixed seas nearing small craft advisory levels
north of CAPE blanco on Wednesday. Northerly winds and shorter
period seas will return late this week into the weekend, highest
south of CAPE blanco -spilde keene

Fire weather Updated 200 am pdt Monday 19 august 2019... Warm
and dry conditions are expected across the area for the next couple
of days. Temperatures will become slightly warmer on Tuesday with
typical humidity values and winds on Monday and Tuesday.

Then, a front will move across the area on Wednesday. This front
will not bring increased cloud cover and higher humidities to the
entire area, and some light drizzle or rain will be possible for
areas west of the cascades on Wednesday. The best chance for
precipitation, however, will be at the coast and west of the coast
range. That being said, this front is not going to bring wetting
rains anywhere. This front is also not expected to bring
thunderstorms to the area, but a few cumulus build-ups could be
possible east of the cascades on Wednesday.

The breeziest days will be Wednesday and Thursday this week, but the
higher humidity values (Thursday trending toward typical, dry,
august humidities) should preclude any need for headlines or other
products. After Wednesday, a return to more typical conditions for
this time of year is expected for the rest of the forecast. -schaaf
