Area forecast discussion, Mar 8, 3:48 PM PST, 2 hours 34 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
348 PM PST Mon Mar 8 2021
.SYNOPSIS...Upper level low off the coast will move slowly south
tonight and Tuesday moving into Northern California Wednesday.
Weak systems spinning out of the low moving through Western
Washington tonight and again Tuesday. Weak upper level trough
dropping down from the north Wednesday. Upper level ridge over the
area Thursday and Friday with a frontal system moving into the
area over the weekend.
&&
.SHORT TERM /TONIGHT THROUGH THURSDAY/...Satellite imagery shows
upper level low well offshore. Cloud cover has spread over most
of the area this afternoon with just the Northwest Interior still
left in the sunshine at 3 pm/23z. Doppler radar has a few showers
in the south Puget Sound and over the Kitsap peninsula but most
of the precipitation is remaining aloft. Temperatures at 3 pm were
in the mid 40s to mid 50s.
Weak upper level disturbance spinning out of the low moving
through Western Washington overnight giving the area a chance of
showers. Upper level low continuing to drift south tonight and
Tuesday with another weak system spinning out of the low arriving
midday Tuesday keeping a chance of showers in the forecast. Lows
tonight will be a little warmer versus last night, in the mid and
upper 30s. Highs Tuesday with more cloud cover will be slightly
cooler, a couple of degrees either side of 50.
Low continues to drop south southeast Tuesday night with the low
weakening and moving inland over Northern California Wednesday.
Low far enough south Tuesday night to keep the weak systems
spinning out of the low south of the area. Weak upper level trough
moving down out of the north Wednesday for another chance of
showers Wednesday afternoon especially for the eastern half of the
area. Lows in the lower to mid 30s Tuesday night with highs
Wednesday similar to Tuesday.
Drying north northeasterly flow aloft developing Wednesday night
as an upper level ridge noses into British Columbia. With the
clearing skies many places Thursday morning will be at of below
freezing.
Upper level ridge moving south with the ridge axis right over
Western Washington Thursday afternoon. Thursday looks to be the
day with the most sunshine in the short term after areas of
morning fog and low clouds dissipate. Highs in the upper 40s to
mid 50s.
.LONG TERM /FRIDAY THROUGH MONDAY/...Flat upper level ridge over
the area Friday for another dry day. Deterministic models pretty
emphatic about a wet system moving into Western Washington over
the weekend. The ensemble members are less enthusiastic about the
front. Model blend only gives chance pops at this point. Will stay
with that for now. Ensembles are trending toward higher pops so
if anything look for the pops to increase for the weekend in
future forecast packages. Drying northerly flow aloft developing
later Monday behind the front but lingering trough will keep a
slight chance of showers in the forecast. Highs in the 50s Friday
and Saturday cooling to the mid 40s to lower 50s Sunday and
Monday. Felton
&&
.AVIATION...An upper low and an associated surface low well
offshore will slowly shift south tonight and Tuesday. A weak
upper level disturbance in the flow aloft will move through the
area tonight. Another one will move into the area from the south
on Tuesday. The air mass will be slightly unstable. Moisture
across the area will increase tonight. It should be mostly mid
clouds but patchy low clouds cannot be ruled out, especially coast
and south interior.
KSEA...Mid clouds tonight and Tuesday with a few spots of rain.
There is a small chance for some lower ceilings in rain tonight
but not enough to put in the TAF. Light east to southeast wind.
Schneider
&&
.MARINE...A low well offshore will shift south tonight and
Tuesday. This low will bring small craft advisory strength east to
southeast winds at times to the Coastal Waters, Strait of Juan de
Fuca, and Northern Inland Waters through Tuesday. West swell
10-12 feet over the Coastal Waters and West Entrance Strait of
Juan de Fuca will subside below 10 feet tonight and Tuesday.

Friday. A front will reach the area on Saturday. Schneider
