Area Forecast Discussion
National Weather Service Seattle WA
925 AM PDT Sat Oct 16 2021

.SYNOPSIS...A front stalled near the north Washington coast will
move ashore later tonight and Sunday. Weak high pressure will shift
over the area Monday and Tuesday. Another front will arrive
Wednesday.

&&

.SHORT TERM /TODAY THROUGH MONDAY/...It is raining over Vancouver
Island where the front has stalled at 930am. There are areas of
blustery southerly winds ahead of the front from around Whidbey
Island northward between Haro Strait and east to around Lummi
Island. Those winds ought to ease through this evening and peter out
overnight as the front weakens/the plume of 850mb winds eases. From
about Mount Rainier southward over the Cascades it is mostly sunny--
and that sunshine extends westward to about I-5 from about Toledo
south. As we head into the afternoon some of that drier air will
probably shift north into the Puget Sound area. There are also some
sunny breaks in the clouds in the lee of the Olympics From Port
Angeles to Port Ludlow so it doesn't look like too bad a day today.

The frontal system stalled just off the north coast and over
Vancouver Island will weaken and move ashore later tonight and
Sunday. The front is oriented SW-NE and it becomes more N-S oriented
through tonight and splits somewhat. The precip that is forecast to
fall over Western Washington on Sunday is disorganized, less
widespread, and fairly light. There will probably be a few showers
behind the front Sunday night and perhaps a little PSCZ activity for
a few hours before the air dries into Monday and we get a break
between weather systems. 19

.LONG TERM /TUESDAY THROUGH FRIDAY/...On Tuesday, the upper level
pattern will feature a weakening ridge of high pressure over the
Pacific Northwest, with a highly amplified, deep longwave trough
over the Pacific. Substantial moisture is noted on the trough's
upstream side, tho will reside far enough offshore to keep the
area dry for one more day.

By Tuesday night and into Wednesday, the next frontal system will
approach the area as a strong shortwave rounds the base of the
broader scale trough. This will also help push the longwave
troughing closer to the region, welcoming us to the next round of
active fall weather. The front looks to weaken as it moves across
the area, but will still likely be associated with more rain and
breezy conditions.

As mentioned in yesterday's afternoon discussion, the overall
pattern continues to look potentially active through the end of
the week, however, there remains some discrepancy in both the
deterministic and ensemble guidance. Most of the uncertainty lies
in the positions of both the mean troughing over the Pacific and
the mean ridging over the Western and Central US. The NBM
continues to portray a very wet extended forecast period but it
does remain possible that much of this moisture will remain to our
west. This would come into fruition if both large scale features
trend a tad westward in future model updates. Will monitor, but
for now will maintain the idea of a continued wet pattern
unless/until model guidance shows a true and convincing westward
trend in the upper level pattern.
