.SYNOPSIS...
High pressure will build over the region Tuesday
through the remainder of the week, bringing in unseasonably warm
and dry conditions with rounds of morning fog and low stratus.
A pattern change is on tap for the weekend, with wet and cooler
conditions returning.
&&
.SHORT TERM /TODAY THROUGH THURSDAY/...
High pressure brings a period of dry and mild weather to
western WA through the remainder of the work week. Expect highs
in the mid to upper 50s with 60s in the interior on Wednesday.
Lows will be a little cooler Thursday morning with 30s over the
south sound. 33
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Wet and cooler weather returns over the weekend as the ridge
shifts east and a trough moves in from the west. Snow levels
will lower to around 4000 feet on Sunday with accumulating snow
possible on the higher peaks and passes like Stevens Pass.
Ensemble members favor a cool and wet pattern moving into next
week for more lowland rain and mountain snow. 33

.AVIATION...
Light west to southwest flow aloft expected over Western
Washington into tonight as an upper ridge axis builds over the
interior West. The low level flow is weakly offshore. The ridge will
remain rather dirty today with varying amounts of high and mid level
moisture filtering across the area as a frontal system moves into
the British Columbia coast late today. Patchy LIFR stratus/fog
across the Southwest Interior will gradually lift and scatter this
afternoon. High level moisture will begin to thin late tonight and,
coupled with weak surface flow, is likely to lead to the return of
LIFR/IFR stratus and fog on Wednesday morning from around KSEA/KBFI
southward.
KSEA...Varying amounts of high and mid level clouds will continue
into tonight. As discussed above, the coupling of thinning high
clouds and weak surface gradients lends moderate confidence to the
return of fog and/or low clouds at the terminal again early
Wednesday morning. Surface winds light and variable much of today
trending more easterly tonight at 7 knots or less. 27
&&
.MARINE...
A decaying system well offshore will bring seas back up to
10-12 feet later this evening into Wednesday. As a result, a SCA
has been issued again for the outer coastal waters. SCA level
winds are also possible around this time - but mainly for the
outer coastal waters where a 40-45% chance exists.
As high pressure builds into today through the remainder of the work
week, expect periods of marine fog over the next few days.
Visibility restrictions in Puget Sound and the coastal waters are
possible as fog and/or low stratus develops. Seas 10-12 ft through
Thursday morning, before setting around 9-10 ft thereafter.
&&
.HYDROLOGY...
The Skokomish River will fall below flood stage late this
morning or early afternoon and will continue to recede. The
river will rise again early next week and crest near minor flood
stage again. Flooding is not expected elsewhere over the next 7
days. 33
