.SYNOPSIS...A series of frontal systems will bring a return of
widespread rain and occasionally windy conditions through the
weekend. A trend toward drier and cooler conditions are expected
toward the middle portion of next week as the storm track
shifts south of Western Washington.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...A weak frontal
system has moved ashore for mainly light rain this afternoon.
The tide gauge in Port Angeles is close to minor flood stage and
a Coastal Flood Advisory remains in effect.
A trough will push inland tonight and Saturday, ahead of the
next strong Pacific frontal system. Pressure is a little higher
Saturday morning and coastal flooding is confined to the San
Juan Islands and western Whatcom County during the morning high
tide. The main impacts with this second system will be strong
winds (coast and San Juans), periods of heavy rain (coast and
Olympics), and large waves (coast). Winds will peak Saturday
night into early Sunday morning. For precipitation totals
through the weekend, we are looking at another 1-3" along the
coast with 0.50-1.00" in the interior. Most of the rain will
fall Saturday night. Due to additional heavy rain in the
Olympics, the Skokomish River is at risk of flooding and a Flood
Watch remains in effect. In addition, this system is generating
large waves offshore that will reach the WA coast this weekend
leading to High Surf conditions. 33
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...We`re under broad, long
wave, troughing Sunday and Monday for isolated to scattered
showers. Temperatures will track closer to average with lows in
the 40s and highs in the lower 50s. An upper low will shift E/SE
and into Oregon midweek, with some light moisture clipping the
WA/OR border. A Rex Block pattern forms toward the end of week
over the West. This blocking pattern keeps western WA dry
through the end of the week. 33
&&
.AVIATION...South flow aloft continues into tonight before
transitioning more southwest on Saturday as the next frontal system
approaches the Pacific Northwest. Steadier light rain continues to
progress eastwards across Puget Sound this afternoon with showers
along the coast. Predominantly VFR conditions continue into Saturday
with periodic MVFR cigs mainly along the Olympic Peninsula and OLM
westwards. Post-frontal isolated showers expected tonight into
Saturday. Brief vsby reductions this afternoon into this evening
across Puget Sound with stratiform rain. The next front arrives
Saturday evening along the coast and moves inland Saturday night
with increasing rain and winds. Surface winds into Saturday remain
southerly with localized gusts to 25 kts along the coast and KBLI.
KSEA...VFR conditions with light rain into this evening. VFR cigs
with continued mid level clouds through Saturday. The next front
arrives Saturday evening into Saturday night for increasing rain.
Surface winds remain southerly, fluctuating between SE/SW at times
into Saturday. JD
&&
.MARINE...A frontal system continues to move across the interior
waters this afternoon. A Gale Warning remains in place through this
evening across the Coastal Waters with SCA for portions of the
interior waters. A brief break early Saturday before southerly winds
increase again Saturday ahead of a stronger weather system offshore.
A Storm Force Warning has been issued for the outer Coastal Waters
Saturday afternoon into Saturday night with gusts of 45 to 55 kts
during this period. A Storm Force Watch remains in affect for the
inner Coastal Waters. Gale Warnings and Watches are also in affect
for the western Strait of Juan de Fuca, Admiralty Inlet, eastern
Strait of Juan de Fuca, and northern inland waters Saturday night.
Additional headlines may be necessary for Puget Sound and the
central Strait of Juan de Fuca with the next system. South winds
will ease a bit on Sunday, but remain elevated, especially for the
Coastal Waters. Winds subside further Monday into early Tuesday
before increasing again going into midweek with a stronger weather
system moving southwards well offshore.
Seas of 20 to 25 feet are expected into Saturday morning. Seas then
range 15 to 20 feet Saturday into Saturday night, building again
towards 22 feet for the outer Coastal Waters again Sunday. These
large waves will also be energetic with a dominant period of 17 to
20 seconds into Saturday. Seas remain elevated before subsiding to
10 to 15 feet on Tuesday. JD
&&
.HYDROLOGY...The potential for flooding continues on the
Skokomish River with periods of heavy rainfall through the
weekend. A Flood Watch remains in effect.
River flooding is not expected on the other rivers in the area
in the next 7 days at this time.
