area forecast discussion
national weather service seattle wa
315 am pdt Sun may 26 2019

Synopsis Drier and warmer conditions are expected to start today
over much of western washington and continue into the week ahead.

Lingering moisture from an upper level low south of the area will
allow for afternoon and evening showers over the cascades most days.

Short term today through Wednesday Current radar proving to
be pretty quiet this early morning with IR satellite imagery showing
some low clouds but clear conditions at the mid and upper levels.

Obs bear that out with a mix of reports ranging from clear skies to
locations more prone to low level clouds fog reporting some
reduction in visibility.

Wrap around moisture from the departing upper low will prove to be
the forecast problem of the day... As it will allow for clouds to
move into the area from the east and linger for much of the day
today. While not likely... This may also pose a slight chance for
showers during the afternoon... And even a stray rumble of thunder up
in the cascades. All things considered... Pops remain pretty
low... Generally in the slight chance category and even then confined
to east of the sound. Temps are expected to rebound to around 70
today for most lowland locations... So as long as one does not mind a
bit of cloudiness... Should be a fine day for any outdoor activities.

Memorial day should meet this criteria as well... If not a bit better
given that clouds will start to thin out overnight tonight giving
way to partly to mostly sunny skies for much of the area tomorrow.

The exception to this being the cascades... Which will see lingering
clouds as well as the lingering chance for showers with isolated
thunderstorms once again possible. Highs for the day will generally
be the warmest of the forecast period for most locations... With
lowland interior locations getting up into the mid 70s. An onshore
push will allow for cooler temperatures Tuesday... Pulling highs back
down to around 70 but upper level ridging over the coastal waters
will exert its influence keeping conditions generally dry into
midweek. Smr

Long term Thursday through Sunday Weak upper level ridging will
remain the predominant weather feature for the remainder of the week
yielding a generally dry pattern... However both GFS and ECMWF show
occasional hints of a stray shower here or there due to disturbances
associated with an upper level trough extending into eastern wa.

Odds... And thus pops... Are not terribly favorable for precip... But
cannot exactly leave 0 pops either. As such... Generally silent pops
of less than 10 pct are present. A weak upper level trough looks to
move into the area Friday night... With both models kind of agreeing
on this... And this will see a rise in pops for near the end of the
forecast period... But models do disagree on how far south the
feature will plunge... And as such have gone with just slight chance
pops at this time. Smr

Aviation Easterly flow aloft becoming northeasterly tonight and
Monday as upper level low well south of the area moves southeast
and an upper level ridge builds into the northern portion of
british columbia. In the lower levels northerly flow today will
become light tonight and tune onshore Monday.

Low level moisture left over from the rain on Saturday has
resulted in low ceilings this morning over most of the interior.

Ceilings in the 1000-2000 foot range this morning with areas of
ceilings below 1000 feet and local visibility 3-5sm in fog.

Conditions improving around 18z with lower layer scattering out
leaving just a mid level, ceilings AOA 10000 feet, over the area
into Monday morning. For the coast and strait just partly cloudy
skies early this morning with areas of ceilings below 1000 feet
and visibility 1-3sm in fog forming 12z-15z. Conditions improving
by 18-19z with just a mid level cloud deck for the afternoon and
evening.

Ksea... Tough call and sea-tac this morning. Ceilings around 500
feet. With northerly winds 6 to 10 knots will not include any
visibility restrictions. Estimated tops around 2000 feet. Above
the surface the flow is light. Will keep the ifr ceilings going
through late morning with the layer scattering out 18-19z. For the
afternoon some mid level clouds. Showers developing over the
cascades in the afternoon but right now the flow aloft does not
look strong enough to push the showers over the terminal in the
late afternoon and early evening hours. Light onshore flow
developing overnight with another round of ifr stratus possible
Monday morning.

Northerly winds 6 to 10 knots becoming light overnight. Felton

Marine Light northerly flow today will turn onshore on
Monday then continue through Thursday. A very weak surface low
will move into the offshore waters Tuesday then dissipate on
Wednesday.

Small craft advisory west winds for the central and eastern strait
of juan de fuca Monday evening and again Tuesday evening. The
onshore flow could be strong enough for gale force winds Monday
night. Felton

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Climate The high in seattle of 56 degrees was only 3 degrees
off the record low maximum temperature for the day ( 53 in 1980 ).

The last time there was a colder may 25th in seattle was 35 years
ago with a high of 54 on may 25th 1984. May 25th has the lowest
record rainfall for any day in may in seattle ( 0.41 inches in
2011 ). The 0.19 inches yesterday was the 5th wettest may 25th in
the 75 years of records at sea-tac. Felton

Sew watches warnings advisories
