Area Forecast Discussion
National Weather Service Spokane WA
1057 AM PST TUE NOV 25 2014

.SYNOPSIS...
Mild and rainy conditions are expected today with the southern and
central Idaho Panhandle receiving rain for much of the day. Snow
levels will be on the rise tonight into Wednesday bringing a break
in the heavy mountain snow. A breezy and wet but warm
Thanksgiving Day will give way to a colder weather pattern for the
holiday weekend with the mountains receiving several rounds of
snow. Snow levels will fall to valley floors by the weekend.

.DISCUSSION...
Updated were made to the forecast today...chiefly to reduce the
chance of precipitation and amount across the northeast zones and
slightly increase pops and raise amounts for areas further to the
south. A shortwave is moving over the ridge and had effectively
shifted the brunt of the moisture further south than previously
expected. This wave is also allowing cooler air to filter into
the region and temperatures for the northern zones have been
cooled off several degrees for today. Rain fall amounts have been
quite impressive since last night. Amounts range from around a
quarter inch to close to 2 inches for the Cascades and a quarter
inch to just over an inch for the central and north Panhandle
mountains.

The cooler air filtering into the northern valleys may result in
several hours of snow this evening before turning over to rain by
morning. otherwise expect wet conditions tonight and Wednesday.

.AVIATION...
18z TAFS: Little change to the previous forecast discussion as we
expect a pretty steady rain today south of a line from the north
Cascades to near or just south of Mullan Pass. Expectprecipitation
to shift back to the north this evening and overnight. Snow levels
keep precipitation as rain at all TAF sites. The abundance of
moisture will result in stratus and some fog for the TAF sites
with conditions wildly fluctuating between MVFR to VFR/LIFR and
back as bands of heavier precipitation moves through the region.
Southwest winds will be on the increase overnight with gusts
15-25kts.Tobin
