Synopsis A cold front will move through western washington
Sunday morning with rain out ahead of the front beginning tonight.

A weak ridge will build over the area on Monday with the next
system moving through the ridge Monday night into Tuesday. Another
system arriving Wednesday night into Thursday with a cool upper
level low over western washington Friday.

Short term tonight through Tuesday Satellite imagery shows
persistent cloud cover over the southwest interior extending up
into king county this afternoon. Partly to mostly cloudy skies
over the remainder of the area. Temperatures at 3 pm 22z were
in the 60s and lower 70s.

Cold front offshore, currently near 130w, will continue to move
east reaching western washington Sunday morning. Rain out ahead of
the front beginning on the coast tonight spreading inland after
midnight. By daybreak Sunday morning rain will be as far east as
the cascades. Front moving through Sunday morning with the
trailing upper level trough right behind the front Sunday
afternoon keeping showers in the forecast. Lows tonight in the mid
50s to lower 60s. Highs Sunday in the lower to mid 60s.

Upper level trough axis moving east of the area by 06z Monday with
just some lingering shower activity in the evening. Flat upper
level ridge building into western washington early Monday
morning for a little break in the rain. Lows Monday morning in the
upper 40s to mid 50s.

Flat ridge remaining over western washington on Monday with a
weakening system trying to move over the top of the ridge giving
the northern portion of the area a chance of rain. Highs in the
lower to mid 60s.

System dissipating over western washington Monday night into
Tuesday morning. 500 mb heights remaining in the mid to upper 570
dms with little in the way of dynamics with the feature. Will
leave the pops in the chance category and confine the rain chances
to just the cascades in the afternoon on Tuesday. Under cloudy
skies lows Monday night will be in the 50s. Highs Tuesday in the
60s.

Long term Wednesday through Saturday Extended models in good
agreement with the ridge weakening on Wednesday and another
system moving down from the northwest reaching western washington
Wednesday night Thursday morning. Very cool for september upper
level low dropping down into the area later Thursday into Friday
lowering the snow levels down to below the higher passes and
possibly below stevens pass Friday morning. Model solutions lose
consistency later Friday into Saturday with regard to how fast the
low moves out of the area and which way does it go, straight
south or slower southeast. With the inconsistency in the models
will leave chance of showers in the forecast for later Friday and
Saturday. Highs both days will only be in the upper 50s to lower
60s. Felton

Aviation An upper level ridge will continue to move out of the
area this evening, making way for an incoming upper level trough.

Flow aloft has started to become more westerly this afternoon and
will become more southwesterly tonight as a result. Current satellite
imagery indicates that the low clouds lingering around puget sound
this morning have started to break up and lift. As a result, current
conditions are mostly MVFR toVFR for most terminals. Overall, expect
gradual improvement of conditions through the remainder of the afternoon
hours. The next frontal system will approach western washington late
tonight and move inland during the overnight hours, brining rain
and MVFR ifr ceilings to the region. Expect southerly winds 4 to 8
knots this evening, increasing to 6 to 12 knots overnight ahead
of the front.

Ksea... Current conditions MVFR. Current satellite imagery indicates
more clouds moving into the terminal this afternoon, however
expect to see improvement toVFR conditions by late afternoon early
evening. Winds southerly 4 to 8 knots. Ceilings will gradually
lower to MVFR again overnight as the frontal system approaches.

Sb

Marine A frontal system will approach the coastal waters this
evening and move inland on Sunday. Small craft advisory southerlies
will be likely for all of the coastal waters ahead of the front
and small craft advisory northwesterlies are expected for portions
of the coastal waters in its wake. A small craft advisory has
also been issued for the strait of juan de fuca Sunday evening
for the strong push of westerlies following the frontal passage.

The next system will move through the region Monday into Monday
night. Sb
