.SYNOPSIS...Weak troughing remaining over the area into Saturday
with cloudier and cooler conditions. Upper level ridge building
into the area Sunday into Monday with warmer and drier
conditions over the region. Weak troughiness returns midweek
with temperatures remaining around normal.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY/...Partly cloudy skies this
afternoon as a front dissipates over western Washington. With
low level flow across much of the area, will continue to see a
mix of sun and clouds throughout the evening hours. Afternoon
high temperatures will warm in the low to mid 70s.
Little change in the pattern heading into Saturday, as we will
see a slight increase in onshore flow resulting in marine
stratus over the interior. The day will start off cloudy but
this marine layer will dissipate into the afternoon, leaving
areas of clouds and sun throughout the evening. Areas along the
coast could see mid to high level clouds across majority of the
day. High temperatures will remain in the low 70s across much
of the interior, with locations on the coast seeing high
temperatures in the low 60s. Winds may become slightly breezy
in the Northwest Interior, with potential to see occasional
gusts up to 20 to 25 mph. Winds will be slightly stronger near
Whidbey Island.
Upper level ridging rebuilds back into western Washington on
Sunday, bringing warmer and drier conditions. Temperatures on
Sunday will warm into the mid 70s, with some areas in the
Southwest Interior seeing temperatures in the upper 70s / lower
80s.
Minor (Yellow) HeatRisk (for those extremely sensitive to heat)
will continue to remain across most of the interior areas
throughout the short term.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...Upper level ridging
will continue over the area with temperatures warming even
further on Monday. High temperatures across the area look to
warm into the low to mid 80s for much of the interior. Areas
along the coast will see temperatures in the mid to upper 60s,
with mostly clear skies. There is increasing chances (25-35%)
for Moderate (Orange) HeatRisk east and south of the Puget Sound
on Monday with these warmer temperatures.
Ridge will shift eastward on Tuesday, allowing for temperatures
to slightly decrease but remain on the warmer side, in the upper
70s.
A weak system looks to brush over the area on Wednesday for a
chance of rain along the coast, the Olympics, and the North
Cascades. Will see increased cloud cover with high temperatures
in the low 70s. Troughiness will continue throughout the
remainder of the week with onshore flow. Temperature`s look to
remain in the low to mid 70s through Friday.

.AVIATION...
A mix bag of VFR/MVFR ceilings out there this afternoon with
some low to mid level clouds across the area. These conditions
will likely remain throughout the afternoon with light low level
flow. Another round of marine stratus looks to enter the area
tonight into Saturday morning, with probabilities of 50 to 70%
of MVFR ceilings. Low ceilings will likely linger areas along
the coast (KHQM KCLM). Light variable winds this afternoon will
shift more southwesterly this evening, around 3 to 7 knots.
KSEA...VFR conditions at the terminal this afternoon with light,
variable winds. Latest guidance shows around a 40-60% chance of
MVFR ceilings generally around 10z-17z. VFR looks to rebound
afterwards in the afternoon and lasting throughout the evening
hours. Winds will slowly transition to a WNW direction this
evening, (03-07z) with speeds remaining light. Winds will then
take a S/SW direction by Saturday morning.
&&
.MARINE...
Surface high pressure will continue over the northeastern
Pacific, maintaining onshore flow throughout most of the
forecast period. Diurnally driven westerlies will continue
likely each afternoon/evening throughout the Strait of Juan De
Fuca. A small craft advisory remains for this afternoons push.
Additional headlines will be likely for more consecutive pushes
each day. A weak front will move over the waters tomorrow with
no impacts. High pressure will continue along with a weak front
midweek.
Seas remain 5 feet or lower through Saturday and will build to
8- 10 feet by Sunday. Seas will subside below 10 feet on Monday.
&&
.FIRE WEATHER...
Even with the slight warming trend into next Monday the low
level onshore pattern will remain intact. This will keep good overnight
relative humidity recoveries in the forecast and help subdue fire
weather concerns despite the warmer temperatures. Another front
in the middle of next week will bring a chance of showers to
portions of the mountains and the coast keeping fire weather
concerns at a minimum.
