.DISCUSSION...
Mostly clear skies and mild to hot temperatures continue this
afternoon, except along portions of the immediate coast south of
Cape Sebastian, where the marine layer has hung on keeping
temperatures in the upper 50s. Southeastern portions of the
forecast area are currently the hottest, with Mount Shasta City
and Alturas at 93 and 94 degrees, respectively. We expect that it
will be hot there, but short of daily records that are 100+
degrees. There is a weak mid-upper level monsoonal impulse
gliding over Modoc and Lake Counties this afternoon that bears
some watching , but we expect any thunderstorm activity that has
a slight chance of getting going will be over Harney County, east
of our area, if it does occurs. There is also a patch of marine
layer stratus over Charleston and Cape Arago at this time, which
is likely a sign of an increase in the marine layer to come
tonight in that area.

The forecast continues to indicate very little change in the
weather across the area during the next 7-10 days. A shortwave
trough moving in on a west-east flow will begin to cool
temperatures Sunday and then, moreso, Monday, for inland areas,
altogether by about 10 degrees for afternoon highs between today
and Monday afternoon. We expect enhanced afternoon and evening
winds at inland locations Sunday and Monday because of this
impulse, and we'll be very close to red flag warning criteria in
Modoc County Sunday afternoon and evening. We also expect a
greater inland push of the marine layer Monday morning, likely
across most of the coastal counties, into central Douglas County,
and, possibly, into portions of Josephine and Jackson Counties.

Otherwise, temperatures will heat back up to 5 to 10 degrees
above normal for Tuesday through next Saturday. With the forecast
area remaining under the axis of high pressure at 500mb during that
time period there will be afternoon and evening low level
instability, but the combination of limited moisture and
subsidence aloft is expected to continue to keep thunderstorms
from forming.

Climatologically speaking, the chance for large fires starting
from thunderstorms in our area peaks mid-July to mid August. Long
term guidance continues to show a more favorable pattern for
thunderstorms as we head toward the end of the month.

Normals for this next week for:
North Bend: Low 52 / High 69
Brookings: Low 52 / High 68
Medford: Low 53 / High 88
Roseburg: Low 54 / High 84
Klamath Falls: Low 48 / High 84
Mount Shasta City: Low 49 / High 84
Alturas: Low 45 / High 88
July Normals for Crater Lake NP Headquarters: Low 41 / High 69

.AVIATION...08/18Z TAF CYCLE...Along the coast and over the
coastal waters...Areas of IFR/MVFR cigs and MVFR vsbys in marine
stratus from Gold Beach south will surge north today. By this
evening there will be stratus along most of the coast. Tonight...the
stratus will surge inland into the lower Umpqua Basin perhaps as far
as Elkton. Meanwhile...the clouds will clear along the south coast
as low level easterly flow develops. The south coast will remain VFR
Sunday while the lower conditions north of Cape Blanco will clear
back to the coast by Sunday afternoon. Inland...VFR conditions will
prevail through Sunday.

&&

.MARINE...Updated 830 AM PDT Saturday 8 July 2017...High pressure
offshore and a thermal trough near the coast will produce strong
north winds and steep choppy seas through next week. Small craft
advisory winds and seas will persist in the waters south of Cape
Blanco through at least Tuesday evening. Winds will peak during the
afternoon and evening hours...strongest south of Gold Beach from 10
to 40 NM from shore. Winds will likely be strongest on Monday
afternoon and evening with gales possible south of Cape Blanco and
small craft advisory conditions north of the Cape.

&&

.FIRE WEATHER...Updated 100 PM Saturday 8 July 2017...The main
concern over the next few days is gusty east side winds combined
with low relative humidities. At this time it appears that
conditions will approach Red Flag Warning criteria over zone 285,
but they will not quite get there except for a few isolated
locations.  Will go with a headline in the Fire Weather Forecast,
but no warning at this time.
