.SYNOPSIS...
Warm and dry conditions are expected to continue over the
weekend. Temperatures remain on track to warm into the upper
70s to mid 80s by Sunday into Monday. Dry and cooler, but still
seasonably warm weather, looks to linger through the remainder
of next week.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
Warm and dry conditions continue with temperatures warming in
the low to mid 70s for much of the interior this afternoon. An
upper level low remains offshore and will push some high clouds
over the interior of western Washington through this evening.
Some increasing light onshore flow will provide some stratus
along the coast spreading inland Saturday morning. Stratus
should dissipate by the afternoon hours leaving another warm and
dry day, with high temperatures warming slightly in the mid to
upper 70s with widespread areas of Minor HeatRisk across the
interior. Progressing into Sunday, temps will warm even further
with areas in the low 80s and mid 80s with areas of Moderate
HeatRisk. The warmest areas correlated with Moderate HeatRisk
are generally places in the Southwest Interior and areas in the
Cascade valleys.
Moderate HeatRisk impacts include those sensitive to the heat
and who may be without adequate cooling. Additionally, though it
will be warm outside, it is important to remember that area
streams, rivers, lakes and the ocean, including Puget Sound, will
still have very cold temperatures often around 50 degrees or
colder. Please be cautious around colder water despite the air
temperatures. Relative humidity also looks to be unseasonably
low across western Washington on Sunday. This poses an elevated
risk of fire danger primarily among dry grasses or dead and dry
vegetation.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...Warm and dry conditions
continue on Monday with increased onshore flow, high
temperatures will drop, but will still remain warm, in the upper
70s. Temperatures will stay in the low 70s throughout the
remainder of the week - with no precipitation expected at this
time.

.AVIATION...
An upper level low will continue to dig southward tonight,
allowing winds aloft to shift from SW to NE. VFR conditions
prevail across the area with marine stratus still lingering
along the immediate Pacific coastline and near Whidbey Island.
High clouds will continue to stream overhead, allowing for VFR
conditions to prevail through the TAF period for most of the
interior. Marine stratus is forecast to redevelop this evening
and creep inland, bringing IFR to LIFR conditions to HQM and
CLM, with the stratus likely ending somewhere between SHN and
PWT, and OLM looks to remain out of the stratus as well. The
stratus should lift and retreat again tomorrow morning.
Generally W/NW winds 3-8 kt will become light and variable
overnight, resuming to N during the day tomorrow, through
slightly stronger (8-15 kt).
KSEA...VFR through the TAF period with high clouds. NW winds 5-8
kt becoming NE 6 kt or less overnight. Winds tomorrow during the
day N 8-15 kt.
&&
.MARINE...
The pattern overall remain stable through the weekend into next
week with high pressure well offshore and low pressure inland.
Gusty northwesterly winds over the far outer coastal waters will
decrease tonight, and a push down the Strait of Juan de Fuca
this evening may reach gusts 20-25 kt this evening. Otherwise,
winds look relatively light until Monday when more robust
onshore flow returns and westerly pushes down the Strait in the
evenings resume Monday night. Seas remain in the 4-8 ft range
through the forecast period.
