.SHORT TERM...Tonight and Saturday...A small cold front is moving
across western Washington this evening which is triggering some
convective instability ahead of it. Radars are showing convective
showers and a few thunderstorms over the Washington Cascades and
eastern slopes at this time. Kittitas county stands the best chance
of seeing some thunderstorms this evening, otherwise the convective
threat will shift east across Washington mainly north of I-90
overnight ahead of the cold front. The cold front will have a narrow
band of precipitation associated with it as it passes over the
northern portion of the forecast area overnight before exiting into
Idaho early Saturday morning with just light amounts of
precipitation on the order of a couple hundreths. Forecast was
updated with adjust some precipitation chances overnight.
