AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
912 PM PST Fri Dec 13 2013

.SYNOPSIS...
A series of weak weather systems will clip the Inland Northwest
through Tuesday bringing a chance for light snow showers at times
for areas mainly near the Canadian border and Idaho Panhandle. On
Wednesday into Thursday a stronger system will bring better
chances for rain and snow. Temperatures are expected climb
slightly above normal through Wednesday before falling back to
below normal for the end of next week. 


&&

.DISCUSSION...
Evening update: stratus has been expanding across the region from
the east/southeast over the past few hours and patchy to locally
dense fog has been noted across the region. The locally dense fog
has been found in the typical locations around the West Plains and
has been noted on web cameras heading toward Spangle. As such
forecast was updated to add this into the forecast now, as opposed
to the prior forecast of it developing largely overnight. This
could produce some slick spots on roads...especially in those
outlying areas...with lows expected to be below freezing. 

Deepening isentropic ascent through the night with the incoming
warm front will have the deepest moisture and best snow chances
tonight remaining toward the ID mountains, expanding through the
northeast WA mountains and surrounding areas by Saturday morning.

Mainly flurries or sprinkles/freezing drizzle will be a threat
across the higher Palouse/Spokane/CdA area west into the northern
Upper Columbia Basin. The threat of more than just flurries will
develop away from the Palouse going into the day Saturday too, but
the threat of more than light accumulations (if any) is low. /J.

.AVIATION...
06Z TAFS: Warm front lifts in Friday night and a weak cold front
sags into the region by late Saturday. Look for primarily IFR 
conditions around the KGEG-KSFF-KCOE area, with LCL LIFR
conditions around KGEG. Brief improvements are possible with any
light snow showers/flurries that may occur with the incoming warm
front during the night. Yet general improvement is not expected
until perhaps later Saturday after 21Z...and greater confidence 
lays around KSFF/KCOE. The southeast flow should keep LWS/PUW VFR 
or lcl MVFR, with drier conditions. Lower confidences lay toward
MWH/EAT, but VFR conditions are expected much of the night, but as 
the southeast flow develops toward morning we could see some
stratus and/or fog and it may persist much of day if it does
develop. /J. Cote
