Area Forecast Discussion
National Weather Service Seattle WA
248 AM PDT Wed Jul 15 2020

.SYNOPSIS...Shallow marine layer clouds along the coast will deepen
on Thursday as a weak front reaches the area. A strong marine push
will occur Thursday afternoon and evening. Friday will be cool and
cloudy with some areas of showers or drizzle. An upper ridge will
build over the weekend and into early next week for a period of
sunny warm weather before another marine push by the middle of next
week.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...Shallow marine layer
stratus along the coast will squirt through the Strait again
tonight. Thursday will see a areas of morning fog or low clouds and
some mid and high clouds will break up over the area as a very weak
front reaches Western Washington. The deeper marine push will occur
Thursday afternoon and night, setting the stage for a few PSCZ
showers and then some drizzle or shower activity through Friday
morning. On Saturday the cool marine air mass will rapidly warm and
dry with the the beginning of a four day warming trend.

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...An upper ridge will build
offshore and then nose in toward Western Washington as a weather
system moves toward the Alaskan Panhandle on Monday--depressing the
ridge offshore. Over Western Washington the air will warm and dry
through Monday--with peak temps on the coast Monday and in the
interior on Tuesday. A marine push will occur Tuesday night or
Wednesday as a weak upper trough reaches the area. The forecast for
next Wednesday looks too warm and sunny, but I will leave it for now.

&&

.AVIATION...VFR conditions will persist into tonight at all TAF
sites. Marine stratus will yield lower CIGs late tonight into
Thursday morning, with widespread MVFR conditions expected and local
IFR conditions possible. Northerly prevailing wind at all sites with
the exception of BLI and HQM where southerly and westerly winds are
expected respectively. Winds generally AOB 10 kts.

KSEA...VFR conditions under mostly clear skies through late this
evening. Marine stratus will push over the terminal late
tonight/early Thursday morning, bringing ceilings down the 1500-2500
feet. CIGs will improve to VFR once again by mid morning. Prevailing
wind out of the north through the period at speeds of 4 to 8 kts
with the strongest winds being observed this afternoon.

Pullin

&&

.MARINE...Offshore high pressure will remain in place for the
next couple of days, with thermal low pressure building up the
Oregon coast. North/northwest winds over the coastal waters with
strongest winds this evening over the coastal waters through the
Strait of Juan de Fuca. The forecast remains on track for a period
of Gale Force winds overnight in the central and Eastern Strait,
with advisory level conditions in the adjacent northern inland
waters. Forecast gradients suggest that winds may remain elevated at
advisory levels through the day Thursday across the Central and
Eastern Strait. Onshore flow will continue through the weekend and
into early next week with additional periods of advisory level
westerlies in the Central and Eastern Strait.

Seas over the coastal waters will build from 3 to 6 ft to 6 to 9
feet by this weekend in conjunction with elevated winds. Seas will
likely remain elevated into next week.

Outside of winds and seas, fog is expected to develop and spread
across much of outer coastal waters and potentially into the Strait
of Juan de Fuca overnight. Areas of dense fog is not out of the
question at this time. This trend will likely continue through the
weekend and into early next week as the overall pattern remains
constant.

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