Area Forecast Discussion National Weather Service Seattle WA 908 AM PST Fri Nov 22 2019

SYNOPSIS. Dry weather into early Saturday with high pressure over the area. Pattern changes by later Saturday into next week as several weather systems usher in chances for precipitation and cooler air.

SHORT TERM /TODAY THROUGH SUNDAY/. Current satellite shows fog in the SW interior as well as all along the Sound this morning and stretching up into Bellingham As such. inherited dense fog advisory will be extended until 11 AM PST. Expecting conditions to improve by then . but given how hesitant fog was to dissipate from the SW interior yesterday . may have to revisit this headline later. Still a few stations reporting temps at or just below freezing . so prospect of freezing fog still exists.

Dry conditions expected again today as upper level high pressure lingers over the area As already stated. fog expected to depart or at least alleviate by noon giving way to generally clear skies but clouds look to return this evening and tonight in advance of the approaching weather system for Saturday. Said system is not likely to bring precip to the area until Saturday night as it starts to pass through W WA with rain continuing into Sunday morning. Models show a general drying expected for Sunday afternoon . although enough moisture will linger where a possible shower or two might still be possible for the remainder of the day. This system will herald in a pattern change as more active weather is expected for the long term forecast period.

High temps expected to be a little cooler than yesterday given the foggy start for some locations . while areas that started off clear will see highs close to yesterday. Highs Saturday expected to be a degree or two warmer for most locations. Overnight lows will be on a bit of a warming trend as clouds move in to the area tonight and remain in place Saturday night with lows tonight ranging from the mid 30s in the SW interior to around 40 along the coast. Lows Saturday night will range in the lower to mid 40s. SMR

LONG TERM /MONDAY THROUGH THURSDAY/. From Previous Discussion . Next system approaches the area on Monday morning and pushes through during the day with upper level low Monday night into Tuesday. This will bring another round of rain + mountain snow and a shot of cooler air from the north. Snow levels will drop to around 2500 feet on Monday and possibly down to 1000-1500 feet on Tuesday. At the lower end of the range, will likely see a rain-snow mix with little to no accumulation. At this time, precipitation amounts don't look super impressive so passes will see another few inches of snow. Early holiday travelers whose plans include the mountains will want to keep an eye on the forecast as there could be a few minor impacts. Afternoon highs on Monday will be in the mid to upper 40s and low to mid 40s for Tuesday as cooler air arrives.

Models diverge past Tuesday with track of the upper level low. Both GFS and ECMWF track the low south from around Vancouver Island down the coast into California but vary in exact position of low and strength. Ensembles are in better agreement with track down the coast so have gone with blended approach for the forecast. Showers will likely linger into Tuesday night then generally taper off Wednesday morning outside a few lingering showers across the Cascades. Regardless of exact track, cooler temperatures look like a safe bet.

Past Wednesday, drying trend continues with models in agreement for a mostly dry but chilly Thanksgiving into Friday. Highs on Thursday may top out in the upper 30s to low 40s with overnight lows below freezing for much of the area.

CEO

AVIATION. Low clouds and fog cover much of the interior lowlands this morning due to light winds and weak mixing. The fog is shallow and will lift by 21z this afternoon, but a few areas may continue to see IFR conditions. Otherwise, dry conditions expected today as an upper level ridge weakens over the region. Mid and high clouds will increase overnight as a warm front clips the area. 33

KSEA . Fog slowly lifting by 21z. Light and variable winds. IFR conditions will likely redevelop tonight before improving Sat morning as south winds increase. 33

MARINE. Weak offshore flow is expected today with seas around 10 to 14 feet. A frontal system will cross the area Saturday and Saturday night (with gales possible through the strait of Juan de Fuca). A second frontal system will drop down from the northwest Sunday night and Monday. Northerly offshore flow will develop on Tuesday. 33

HYDROLOGY. Precipitation moving into the region over the weekend into next week will lead to some rises on area rivers, but river flooding is not expected for the next 7 days. Snow levels will also drop with each system with snow falling at higher elevations.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
