257 pm pdt Sun aug 18 2019

Short term The high pressure ridge centered offshore, is
weaker today due to a shortwave upper level trough moving down
from the north. This trough will remain well north of the area, so
expect little change in the weather pattern for inland areas. Very
warm and dry conditions have continued today over inland areas. Of
note, gusty southwest winds are expected this afternoon through
early this evening east of the cascades as well as gusty south
winds in the shasta valley. Winds have already picked up in the
shasta valley and east side areas with gusts of around 25 to 30
mph. These winds will continue through the early evening, before
lowering. At the coast, the surface thermal trough has weakened
today. As a result, winds have trended lower compared to
yesterday. Also areas of fog and low clouds have persisted
through the day along the curry coast. Areas of low clouds or
patchy fog may also develop this evening and tonight along the
coast north of CAPE blanco and into the coquille and portions of
the umpqua valley.

The upper level ridge will build inland over the region late
Monday and Tuesday. This will bring continued very warm and dry
conditions to inland areas. Expect mild weather along the coast
with areas of low cloud possible during the overnight and morning
hours.

A weak front will approach the area Tuesday and models continue to
show that this front will gradually move into the oregon coast
late Wednesday. Although the front is expected to weaken as it
moves inland and into the ridge, there remains a chance for rain
along the coast and inland into douglas county. Model and ensemble
forecasts have trended slightly stronger with this front. So have
increased the chances for rain over northwest portions of the
area late Wednesday and Wednesday night. South of the umpqua
divide and east of the cascades, expect continued warm and dry
weather on Wednesday and Thursday.

Long term Friday through Sunday... Models continue to show
another weak front moving towards the area Friday night and
Saturday. However, this front is expected to be weaker and move
inland north of the area. So have kept dry conditions in the
forecast through the period and above normal temperature for
inland areas. On Sunday, ensemble forecasts show the upper level
ridge strengthening offshore and extending into the area. At the
surface, a thermal trough may develop along the coast and
strengthen late Sunday. This may bring gusty north winds to the
coastal waters and coast along the potential for gusty northeast
winds over the coastal mountains Sunday night.

Aviation For the 18 18z tafs... Areas of MVFR ifr along the
coast south of gold beach may clear late afternoon. Ceilings could
return to the coast and coquille again this evening into tonight,
but confidence is moderate due to tricky interactions between the
marine layer and light offshore winds.

Elsewhere,VFR conditions will continue through the TAF period with
seasonably gusty winds late in the afternoon and evening hours for
most inland areas, including medford, klamath falls and roseburg.

Marine Updated 230 pm pdt Sunday 18 august 2019... Mostly light
winds and low seas will prevail over the waters tonight through
Tuesday morning. A cold front will bring a period of south winds
Tuesday afternoon into Wednesday with building swells late Tuesday
night through Thursday. Model data continues to suggest waves
peaking at 8 or 9 feet at 12 seconds, just below small craft
advisory levels. Northerly winds and shorter period seas will return
late this week into the weekend, highest south of CAPE blanco. -

Fire weather Updated 200 pm pdt Sunday 18 august 2019... Warm
and dry conditions are expected across the area for the next
several days. Temperatures will remain stable through Monday before
becoming slightly warmer than normal by Tuesday into Friday. Gusty
winds with low humidities will be seen for a short period Sunday
afternoon in the shasta valley and east of the cascades, but are
expected to remain below red flag criteria. One particular area of
concern is the southeast corner of zone 624, roughly south of a line
running east from bly to the warner mountains, where critical
conditions are possible fora brief time this afternoon and early
evening. Humidities are expected to rise slightly beginning Monday,
and with afternoon winds weakening, a return to more typical
conditions for this time of year is expected for the first part of
the week.

Confidence in the long term forecast remains low, but models are
showing a distinct trend towards continuing dry and warm conditions
for next week, with above normal temperatures resulting from a
building ridge aloft. There are a few indications that a weak
impulse could pass through the region Thursday, producing breezy to
gusty winds and enough instability for an increased risk of
lightning Thursday, but mid level moisture is too low for any
confidence in thunderstorm development at this time. Otherwise,
there is no significant chance for precipitation, other than some
light rain or drizzle along the coast. -bpn
