Area forecast discussion 
National Weather Service Spokane Washington

Synopsis...
breezy with light showers will decrease early evening across the
inland northwest. Another weather system will arrive by early
Wednesday morning and bring some light accumulating snow in the
mountains. The best chance for widespread rain is expected
Thursday afternoon into Thursday night. At this time the Easter
weekend looks to be mild and dry.

Discussion...
quick update to remove most of the evening shower wording.
Isolated showers remain across portions of Shoshone and eastern
Kootenai, Benewah and Latah counties. They will be ending in the
next hour or so. Also increased cloud cover overnight. High clouds
over the area now will thicken and lower overnight ahead of the
next weather disturbance to move into the area. Tweaked slightly
the chance of precip overnight. Models agree that any precip that
falls in the overnight hours should be restricted to the Moses
Lake area westward. So took out precip chances across the blue
mtns and Camas Prairie /Nisbet

Aviation...
00z tafs: light showers through 03z with the highest
concentration over the higher terrain of Idaho. Gusty westerly winds
will prevail with speeds of 10-20kts and gusts to 30kts. The
strongest winds will stretch from keat-kmwh-kpuw_klws. Wind gusts
and convective clouds will decrease after 03z. The next weather
system is already spreading high clouds, which will thicken and
lower through the night. A broad overcast deck and a chance of
light showers will start aft 08z across the central part of Washington and
spread east through the early morning hours. Rain showers will be
a good bet across most of eastern Washington and north Idaho aft 18z.
