.DISCUSSION...An upper low off the southern British Columbia
coastline continues to bring unsettled weather to the area. The
upper low is forecast to shift slowly south along the Pacific
Northwest coastline...bringing rounds of steady precipitation
mixed with showers through at least the first part of next week.

The first round of steady precipitation will begin impacting
southern Siskiyou county Sunday morning...impacting the west side
by Sunday afternoon. The activity will spread east through the
day. Another round of precipitation spreads from west to east
early Monday morning into the afternoon hours.

Snowfall along the southern Siskiyou passes will be the biggest
impact of the storm...and a Winter Storm Warning was issued to
account for this hazard. Please see the warning for additional
information.

Scattered showers linger through much of Tuesday before the upper
low moves southeast into northern California allowing for upper
level ridging to set up over the area Wednesday into Thanksgiving.

Unfortunately with high pressure building over the area...there is
the possibility of dense fog over the valley locations...so
warm days aren`t expected.

One thing we do have confidence in regarding this pattern change
mid next week...dry weather through at least the holiday weekend.
In fact...only 1 ensemble member...so about 3% of the models...are
showing any precipitation from Saturday through the following
Tuesday after Thanksgiving.

.AVIATION...23/18Z TAFS...Shower activity will continue into the
afternoon hours as an upper level disturbance moves through the
region. MVFR and IFR ceilings more likely closer to the coast with
VFR ceilings more likely farther inland. The atmosphere will become
unstable later this afternoon along the coast with some isolated
thunderstorms. The chance of any cloud to ground lightning is about
15%.

Valleys will likely see some fog later tonight with partial
clearing. Medford(MFR) is the most at risk here, although
Roseburg(RBG) could see also see a few hours of fog later tonight.
LIFR and IFR visibilities will be possible in these fogs.
