Area Forecast Discussion
National Weather Service Spokane WA
1006 PM PST MON NOV 24 2014
.SYNOPSIS...
A wet and mild storm system will arrive tonight and persist
through Tuesday night. Rain and mountain snow is expected to
develop this evening. Minor snow accumulations are expected in the
valleys near the Canadian border this evening, meanwhile
significant mountain can be expected across northeast Washington
and much of north Idaho. 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...
A shortwave disturbance is pushing over the eastern Pacific ridge
of higher pressure. Current satellite imagery shows this shortwave
crossing into central and southern Alberta late this evening. Good
moist isentropic ascent out ahead of this feature is producing
widespread precip across much of the ID Panhandle and the
Northeast mountains this evening. There has been enough drier air
at low levels to prevent much of this precip from expanding out
into eastern WA. Latest radar scans indicates that not too far
weest from Spokane and Pullman into the basin that much of this
area is dry. The flow pattern begin to veer overnight into Tuesday
morning. This will shift the focus for precip into southeast WA
and into the ID Panhandle.
The main changes made to the forecast for tonight was to lower sow
levels across the Northeast Mtns and into the ID Panhandle. Most
locations above 2500 feet closer to the Canadian border are
seeing snowfall tonight; this includes: Lauier, Northport,
Metaline Falls, Bonners Ferry, Priest Lake area, and Sandpoint. We
have received one report of around an inch of snow near Metaline
Falls through this evening. This compares well with what is
mentioned in the Winter Weather Advisory. Widespread valley
snowfall of more than 2 inches is not anticipated; although,
locations near the Canadian border will see the best chances.
Roads will likely see a layer of wet snow and will result in some
difficult travel across these areas. The heaviest accumulations
are still expected to occur above 4000 feet in elevation. Mountain
locations are expected to see between 3 to 6 inches of snow
through tonight with the first round of precip. More snow is
expected tomorrow tonight with a second round. Snow levels by this
time will be on the increase with less in the way of valley
accumulations expected.

.AVIATION...
06Z TAFS: A steady amount of stratiform precip will continue
across extreme eastern WA and into the ID Panhandle through
tonight. This precip will begin to shift more into southeast WA
and into the Central Panhandle through Tuesday morning before
swinging back up north along a warm front. Cigs and vis will lower
into MVFR/IFR category through tonight. There may be some
improvement across the Spokane/Coeur d'Alene corridor in the
afternoon before the second round of rainfall picks up in the
evening. /SVH
