Synopsis...
a strong and wet Pacific weather system passage has resulted in
widespread rain this Thursday night, with windy conditions late
this Thursday night into Friday. A weaker front will bring mainly
windy conditions Saturday afternoon and night with some showers
across the north. Easter Sunday should be mild and mainly dry.
Active and occasionally showery conditions will continue through
the new work week.

Discussion...
updates primarily to delay slightly the wind increase
tonight...still expecting substaintial Post frontal wind gusts
tomorrow but delayed onset tonight by a few hours. Otherwise the
decreasing pop trend continues on into tomorrow and that may be
adjusted as well if the radar and model data merrit the
adjustment, because right now there is just enough activity on the
radar to leave it alone. /Pelatti

Aviation...
06z tafs: a cold front and the cold conditionally unstable
airmass behind it will support showers off and on during the
overnight hours with a general decreasing trend going into
tomorrow. The expectation is however that wind will increase
overnight and peak Friday morning with wind gusts as high as 40
mph or so before decrease again in the afternoon. Some of the
clutter rain showers could result in brief IFR ceilings at times.
