.SYNOPSIS...
Areas of low clouds and fog will persist across portions of
Inland Northwest as high pressure remains in place. The ridge of
high pressure will begin breaking down Sunday. This will result in
in a good chance for rain and snow through much of the upcoming
week.

.DISCUSSION...
Evening update to downplay impacts from fog tonight. I do expect
there will continue to be some patchy fog around the region,
especially between 2,000 and 4,000 feet in elevation. There will
also be some spots between these elevations that may see some
dense fog at times. However, much of the low clouds across the
valleys around the region has lifted into a low stratus deck. This
is in large part due to the shortwave trough of lower pressure
that is skirting across southern BC. This disturbance is also
producing a lot of high clouds across the central and northern
portion of the region, which is not allowing the lower levels of
the atmosphere to radiate out as well.

There has also been some very light precip falling out of the
stratus cover this evening. Much of this precip has varied from
drizzle (below 2,000 feet) to flurries between Deer Park to
Spokane. A mix of drizzle and flurries is expected to continue to
be a possibility through tonight. Road temperatures are beginning
to drop to below freezing as well, so the possibility for some
slick spots is expected through Saturday morning. Main concern
for any black ice will be on the side streets that receive less
traffic volume or may not be treated. /SVH

.AVIATION...
06Z TAFS: An expansive deck of low stratus has dug in over the
Inland Northwest below 4000 feet agl. There is a weak upper level
disturbance pushing northwest to southeast just north of the
Canadian border. This is producing some high level clouds east of
a line from CYYF to KHMS. The stratus cover is deep enough that
off and on flurries are expected across extreme eastern WA and
into the ID Panhandle through Saturday morning. High level clouds
will begin to clear the region early Saturday morning, which may
result in a slight lowering of the stratus deck. Expect mainly cig
restrictions and varying between IFR and MVFR category. /SVH
