Area Forecast Discussion
National Weather Service Spokane WA
746 AM PDT THU OCT 23 2014

.SYNOPSIS...
Breezy and unsettled conditions will continue today...followed by
some light rain Friday. A strong cold front passage Saturday
Night and Sunday will produce very windy conditions with gusts
in excess of 40 mph. The pattern will continue to be active into
early next week. This includes the potential for widespread rain
into early next week as moisture associated with former typhoons
makes its way toward the Pacific Northwest.

.DISCUSSION...
Forecast updated to increase pops and qpf based on how filled the
radar is with returns this morning along with many surface
obseration sites reporting some measurable rainfall this morning.
The chance of thunderstorms this afternoon remains in the forecast
as the atmosphere becomes conditionally unstable north of the
large baroclinic band associated with the jet stream which is to
passing to the south through Oregon and bending up and exiting
through parts of North Idaho and into Northwest Montana. May go
back and increase surface wind gusts this afternoon as the upper
level winds near 700mb at KOTX were near 50kts and around 35kts at
800mb and convection in this conditionally unstable airmass is
likely to mix these robust upper level winds down to the surface
as wind gusts. /Pelatti

.AVIATION...
12Z TAFS: Moist occluded front will continue to cover the SE
forecast sites through most of the day. This will equate to
periodic or at least vicinity showers through 00z for LWS and
PUW. The shower threat will increase for all locations as a
shortwave trough crosses the Cascades around 18z...and heads into
eastern WA/north Idaho between 21-00z. Thunderstorms are a
possibility across the eastern third of Washington and the Idaho
Panhandle...as well as the threat of wind gusts from 30-40kts.
Despite the unsettled weather...cigs will generally remain in the
VFR category. Weather will dry at all sites overnight as shortwave
ridging moves in. Fog and stratus will be a possibility...but
too small to place in forecasts for now. fx
