Area Forecast Discussion
National Weather Service Spokane WA
1238 PM PST Mon Feb 20 2017

.SYNOPSIS...
The weather pattern will remain unsettled and stormy through 
early this week. A pair of mild and wetter weather systems are 
expected Today and Tuesday, leading to moderate precipitation, 
higher snow levels and renewed concerns of flooding. Cooler and 
showery weather is forecast for Wednesday and continuing for the 
rest of the work.

.DISCUSSION...

Okanogan, Douglas, Ferry, and Boundary counties have been removed
from the Flood Watch. Northern portions of Stevens and Pend
Oreille counties have also been cleared from the watch. These
areas will largely remain in the cold sector of today and into
tomorrow. Rapid runoff is not anticipated during the next 24 to 48
hours. Precipitation for the remainder of today and tonight over 
these areas will largely fall as light rain or a rain/snow mix.
For Tuesday, the lion's share of precipitation on the GFS, NAM and
Canadian models is expected along and south of the Interstate 90
corridor. Temperatures over southeast Washington and the
central/southern Idaho Panhandle will also be warm enough to
contribute runoff through snow melt. If the track of Tuesday's low
pressure system follows the GFS/NAM/Canadian track we can expect a
quarter to half inch of precipitation for the Spokane and Coeur
d'Alene areas. Precipitaiton amounts of a half to three quarters
of an inch will be likely for the Palouse, the Blue Mountains and
the Central and southern Idaho Panhandle. Rises on creeks and
small streams are expected along with field flooding in areas 
with poor drainage. /GKoch

quiet evening. The next Pacific system starts to move in aft 12Z
