Area Forecast Discussion
National Weather Service Spokane WA
1241 PM PST Sat Jan 20 2018

.SYNOPSIS...
A cool and moist westerly flow will bring snow showers to the
mountains and northern valleys today. A stronger system looks to
bring another round of snow Sunday. An active weather pattern
should continue into next week with moderate snow possible
Tuesday into Wednesday.

&&

.DISCUSSION...
Minor update to high temperatures today mainly over Central
Washington. Compact upper low early this afternoon has shifted
towards the Spokane/Coeur d`Alene area and will continue to move
east and weaken into this evening. Behind this wave sun breaks
have allowed temperatures to warm slightly warmer than previously
though and temperatures were increased for places such as
Wenatchee, Moses Lake, Ritzville, and Pullman. A few other minor
temperature adjustments as well.  JW

.AVIATION...
18Z TAFS: A compact but vigorous short wave trough over Central WA
will pass through the region through this afternoon promoting
scattered snow showers with generally MVFR ceilings and
visibilities mainly over the eastern TAF sites while the western
sites will benefit from some downslope off the Cascades. A shallow
area of fog over KEAT should be completely gone by 1930z as area
web cams show this to be a narrow patchy of fog with clearing over
much of the city. A break period is expected tonight ahead of the
next storm system, which will spread -SN and MVFR conditions into
KEAT Sunday morning. JW
