Grandview, Washington

... Light freezing rain possible this morning and tonight...

The leading edge of warm frontal precipitation will persist over
the Cascades this morning and continue to impact the area for the
next two nights and mornings. There will be a marginal warm layer
setting up over the Cascades with cold air possibly trapped in
the valleys along the east slopes. This combination has a slight
potential to produce very light freezing rain during the morning
hours. Precipitation amounts are expected to be a few hundredths
of an inch or less... thus the main impact is expected to be black
ice on roadways and especially on overpasses during the night
time and early morning hours. There is only moderate confidence
that this event will occur. Please continue to monitor the latest
forecasts and statements from the National Weather Service or
your local media outlets should additional statements be issued.
