Area Forecast Discussion
National Weather Service Spokane WA
1105 PM PDT Tue Oct 17 2017

.SYNOPSIS...
Winds will subside quickly by sunset this evening. A moist frontal
system will bring a good chance of rain and mountain snow to
Washington and north Idaho on Wednesday. A wet and windy weather
pattern is expected to continue through the weekend. A return to
mild and drier conditions is expected early next week.

.DISCUSSION...
We are getting some reports of down trees and power lines in the
valleys of northeast WA. These reports seem to be fairly scattered
about. These kind of reports are typical of an event like this
with good strong winds. We are not expecting these kinds of
impacts through the rest of the night. In fact, we should be
seeing winds calm down rather quickly through the evening and winds
have weakened enough that we decided to drop our Wind Advisory
early. I also removed the fog from the forecast for tonight in the
valleys of northeast WA and in the Northern Panhandle. These is
very dry air moving in behind the cold front with dew points
dropping down into the teens. We should also see high clouds
thicken up ahead of the warm front set to move in tomorrow. /SVH

.AVIATION...

06Z TAFS: The next Pacific storm system will begin to impact the
region today. The effects from this storm system will stretch over
the next few days. The warm front will push across today. Clouds
will thicken over the region tonight. Light rain will pick up in
the afternoon. Strong westerly flow should result in a rain shadow
in the lee of the Cascades with KEAT and KWMH seeing little precip
if any at all. Not much rain is expected at KPUW either and KLWS
will likely be shadowed out by the Blue Mtns. Confidence is high
that the Spokane/Coeur d`Alene corridor will see rain beginning
right around noon then decrease Wednesday evening. VFR conditions
are expected as cigs will remain above 4-6 kft agl and rain
shouldn`t be heavy enough to drop vis below 6 SM. /SVH
