area forecast discussion

910 am pdt Thu jun 20 2019

Synopsis A few lingering showers today as an upper level
low pushes east of the area. Dry weather expected for Friday and
Saturday as weak high pressure builds in. Another trough will
approach the area late Saturday and settle over the region through
early next week.

Short term today through Saturday Radar is generally
quiet... Although there are some lingering showers from a convergence
zone over southwestern portions of snohomish county. While the
chance for showers will fizzle out through the day... Except for over
the cascades... It does look like clouds will linger today and
tonight as the upper level low responsible continues to slowly move
eastward... Lessening its impact over the area. High temps today
should be a little bit warmer than yesterday... Although still
comparably cool compared to what has been seen for most of
june... With interior lowland temps in the lower to mid 60s and right
around 60 along the coast.

A weak upper level ridge will start to affect the area Friday with
dry conditions and diminishing cloud cover. Afternoon highs will
also climb back into the upper 60s to lower 70s for the interior.

The ridge axis will push inland on Saturday... Allowing for these dry
conditions to persist and temperatures remaining steady. This ridge
flattens out by Saturday evening as an upper level low starts to
approach from the gulf of alaska.

Inherited forecast covers the short term fairly well with no morning
updates planned. Smr

Long term Sunday through Wednesday From previous
discussion... Another upper trough will slide southwards along the
british columbia coast Sunday into Monday. Showers will likely be
around both days as the upper level low pushes south just offshore.

Both GFS and ECMWF are in decent agreement on the track of the upper
low with it positioned off the oregon coast on Tuesday. Pops kept
for Tuesday, though guidance suggests precipitation may be limited
given the location of the low well to the southwest. The upper low
then looks to swing back into the area for Wednesday with an
increase in shower activity. Temperatures will generally be in the
60s with low 70s possible in places for Tuesday and Wednesday. Jd

Aviation Moist northerly flow aloft will continue today, with
some drying of the air mass likely this afternoon and evening. At
the surface, moderate onshore flow will continue. The air mass is
mostly stable, though a convergence zone will persist this morning
in snohomish and king counties. Ceilings are quite variable, but are
generallyVFR except MVFR in and near the convergence zone.

Ksea... Convergence zone seems likely to remain north of the
terminal today. Ceilings should remain mostlyVFR. Wind southerly 4-
8 kt this morning, increasing to 8-12 kt this afternoon and evening.

Wind will make a run at turning northerly for a few hours this
evening, but will probably only get to westerly. Chb

Marine Onshore flow of varying degrees of strength will continue
through early next week. Westerly flow in the strait will reach high
end small craft advisory levels this afternoon and evening, and gale
force winds are not out of the question. There will be outflow
advisory level wind in admiralty inlet and the northern inland
waters as well.

Onshore flow will continue into the weekend as high pressure remains
offshore. Westerly advisory level winds are possible each day in the
strait. Gales are possible Saturday evening. Chb

start of the next rainy season; it will only be updated as needed
until then.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
