Fire Weather Planning Forecast for Western Washington
National Weather Service Seattle WA
524 AM PST Thu Feb 23 2017

Current warnings/watches...none.

.DISCUSSION....Cooler than normal temperatures are expected to
persist over Western Washington for the next several days. Systems
embedded in northwesterly flow aloft, along with an unstable air
mass, will result in showers at times. Temperatures aloft will be
cold enough that any showers in the lowlands that fall during the
late night and morning hours may fall as snow, or mixed rain or
snow. Brief accumulations in the lowlands, if they occur, will be
light over the next few days. Temperatures will begin to moderate
to near normal toward the middle of next week.

 Forecast for 20 foot wind speed (valleys and ridge tops) are 10
 minute averages reflecting RAWS winds.
