Area Forecast Discussion
National Weather Service Spokane WA
1040 AM PST Fri Jan 20 2017

.SYNOPSIS...
Periods of light snow are expected today and into the weekend for
the East Slopes of the Cascades. For the remainder of the Inland
Northwest the best opportunity of accumulating snow will be on
Sunday. A drier and colder weather pattern is expected next week.


&&

.DISCUSSION...
Current 12Z KOTX sounding shows that atmosphere over Eastern
Washington and Northern Idaho is overall slightly cooler than it
was 24 hours ago...and this is quite evident in the slower start
to thawing of ice and snow at lower elevations in the area. Still
the expectation is disturbances pivoting around an area of low
pressure just off the coast will move southwest to northeast
and have the biggest impact on the western half of the forecast
area...thus highest pops of the day remain over the western half
of the forecast area. Have adjusted temperatures slightly with a
morning update...primarily to warm some locations up a few
degrees. /Pelatti

.AVIATION...
18Z TAFS: Some of the weather disturbances rotating around an
area of low pressure just off the coast will move over the
aviation area during the next 24 hours. The resulting snow and
mixed wintry mix of precipitation will bring about MVFR/IFR
ceilings and visibilities at times. /Pelatti
