.SYNOPSIS...Strong high pressure continues to remain over the
region this week, maintaining unseasonably warm and dry
conditions across western Washington. Expect a return to cooler
and wet conditions this weekend, with snow levels falling to
around 3000 to 4000 ft for the start of next week.
&&
.SHORT TERM /TODAY THROUGH SATURDAY/...Strong high pressure
remains in control for more dry and mild weather. The main
difference today is an increase is lowland fog, mainly in the
interior, with visibilities down to 1/4 mile or less in spots -
a Dense Fog Advisory is in effect. Otherwise, expect sunny
conditions this afternoon with highs around 60. Will likely see
similar conditions on Friday. Rain returns on Saturday as the
ridge exits east and a front moves in from the west. 33
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...Western WA
remains under moist southwest flow early next week for more
lowland rain and mountain snow. Snow levels will lover to around
3000 ft Sunday night and Monday with accumulating snow expected
in the mountains and passes. Heavy precipitation in the SW
Olympics will keep the Skokomish River running high and close to
minor flood stage. An upper low keeps the air mass cool and
showery moving toward midweek. 33
&&
.AVIATION...Southwest flow aloft becoming more southerly
tonight as an upper- ridge continues. Clearing mid-high level
moisture has allowed widespread LIFR fog to develop. This will
persist into the morning before VFR conditions return by 20-22z.
Fog may struggle to lift out of the Chehalis River Valley today
- impacting terminals such as KOLM as a result. Winds through
the forecast will remain light and variable between the NE/SE
less than 5 kt, increasing to 4-8 kt during the day today. Fog
again possible overnight into Friday morning.
KSEA...LIFR conditions with fog and/or low clouds and periods of
surface visibility below 1SM have developed and are favored to
persist through 18-21z this morning. VFR is expected again
thereafter. Surface winds N/NE 7 to 10 knots today becoming more SE
overnight into Friday morning.
&&
.MARINE...Increasing offshore flow today as a surface high over
the interior interacts with broad low pressure offshore. SCA
gusts are possible over the Northern Inner coastal waters as
easterlies traverse through the West Entrance of Strait of Juan
de Fuca. SCA seas persist for the coastal waters - likely into
the weekend. A series of frontal systems will begin to reach the
waters this weekend into early next week.
A Dense fog advisory has also been issued this morning for the
inland water zones of Puget Sound, Admiralty Inlet, and Northern
Inland.
&&
.HYDROLOGY...Heavier precipitation over the weekend and early
next week will force rises on the Skokomish River in Mason
County with the river close to minor flood stage. Flooding is
not expected elsewhere over the next 7 days.
