Area Forecast Discussion National Weather Service Seattle WA 400 AM PDT Thu Jul 29 2021

SYNOPSIS. Upper level ridge building over Western Washington through Friday. The ridge will remain over the area Saturday then shift east Sunday and Monday. High temperatures peaking Friday with a marine push Sunday cooling temperatures back down to near normal. Southerly flow aloft combined with a slightly unstable air mass over the Cascades could produce some showers late in the day over the weekend. Upper level trough approaching from the west and low level onshore flow will keep temperatures near normal the first part of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. Satellite imagery shows thin layer of stratus along the coast and down the Strait of Juan de Fuca. Mostly clear skies over the remainder of the area. Temperatures at 3 am/10z were in the mid 50s to mid 60s.

Today will be a lot like yesterday with upper level ridge over the area and weak low level onshore flow. Temperatures aloft warming slightly combined with a little weaker onshore flow this afternoon so have gone for highs a couple of degrees warmer. This puts locations from Seattle southward near 90 with 80s over the remainder of the interior. Highs along the coast in the 70s and lower 80s.

Upper level ridge continuing to build over the area tonight and Friday with weak low level onshore flow. Model 850 mb temperatures warming from plus 18 to 22C today to plus 22 to 25C Friday but with the low level flow not turning offshore high temperatures will only be a couple of degrees warmer Friday, mid 80s to mid 90s for the interior and mid 70s to lower 80s for the coast. Lows tonight in the mid 50s to mid 60s.

Upper level ridge remaining in place Friday night into Saturday with an upper level trough beginning to dig offshore. This will cause the flow aloft to become more southerly and open the door for some possible late afternoon/evening convection over the Cascades Saturday. Low level onshore flow increasing Saturday afternoon cooling high temperatures along the coast back into the lower 70s. Highs over the interior will also cool with the warmest locations in the upper 80s and highs over the northern interior lowering into the upper 70s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. There is general agreement in the extended models with a vort lobe embedded in the southerly flow aloft moving by mostly to the east Sunday. Model ensembles have anywhere from 15 to 25 percent of the solutions producing some light showers as far west as Seattle Sunday. Confidence is not very high in this scenario given the variability in the models but too many ensemble solutions with light precipitation so will have a slight chance of showers from about the Puget Sound eastward. With low level onshore flow bringing in low level moisture and mid level moisture from the vort lobe will word the forecast mostly cloudy. Highs will be in the mid 60s to upper 70s.

Upper level trough remaining offshore Monday and Tuesday with an upper level ridge to the east. A pattern we have seen much of July. Low level flow remaining onshore keeping high temperatures near normal with some morning cloud cover. Big differences in the operational runs Wednesday with the GFS showing a consolidated front approaching the north coast. The ECMWF operational run much weaker and further north with this feature. GFS ensembles more in line with the ECMWF solution. Will have slight chance pops for the North Coast and Olympics in the forecast. High temperatures will remain near normal. Felton

AVIATION. Low clouds/sub-VFR ceilings continue to expand southward along the Coast and down the Strait of Juan De Fuca early this morning, with just a few high clouds noted elsewhere. For the remainder of the morning hours, VFR should prevail at most TAF sites, with HQM likely to see LIFR-IFR ceilings develop towards daybreak. CLM may also see a brief period of LIFR-IFR ceilings as stratus expands across the Strait. Stratus will burn off late morning, leaving generally clear skies through the afternoon and evening. Winds light and variable, becoming N 5-10kts late this morning.

KSEA . VFR. Winds N 5-10kts.

Kovacik

MARINE. Onshore flow to prevail for much of the forecast period as high pressure remains the dominant feature offshore. The biggest forecast concern over the period will be the strength of each evening's diurnal westerly push down the Strait. Current guidance indicates winds will be borderline SCA this evening, so have opted to issue this headline for the Central Strait and East Entrance. Stronger pushes are then expected Friday evening/night and again on Saturday evening/night, where gale force winds still cannot be ruled out. Stronger pushes will also likely bring SCA winds to Admiralty Inlet and Northern Inland Waters. Gale force winds then look likely again for Monday night for the Strait.

Outside of the winds down the Strait, periods of SCA winds are likely over the Coastal Waters through the weekend. Seas will be benign through the period under 5ft.
