Area Forecast Discussion National Weather Service Seattle WA 913 AM PST Thu Nov 21 2019

SYNOPSIS. Dry weather continues into early Saturday as high pressure remains in place. Pattern changes begins later Saturday into next week as several weather systems usher in chances for precipitation and cooler air.

SHORT TERM /TODAY THROUGH SATURDAY/. Chilly start to the day as many locations in W WA still in the 30s at the time of this writing. Fog and low clouds still present over the south Sound and into the SW interior stretching as far north as Sea-Tac . but generally clear elsewhere. Aforementioned fog should lift by noon today.

Another dry day with generally clear skies as the upper level ridge axis exits the area today. May see mid to high level clouds increase as the ridge makes way for a shortwave disturbance approaching the area tonight. Any precip with this feature will stay well to the north The shortwave ejects quickly. gone by mid morning Friday . and a secondary weak ridge keeps dry conditions in place for most of Friday. Temperatures Friday will be similar to today, maybe a degree or two cooler.

Pattern change then begins to take shape for the weekend into next week. Ridge will flatten on Saturday ahead of a more organized system that will begin to approach the area during the day Saturday. Most of the morning to afternoon hours will remain dry outside of a few showers across the Olympic Peninsula and far northern interior.

SMR/CEO

LONG TERM /SUNDAY THROUGH WEDNESDAY/. From Previous Discussion . Aforementioned system drops SE through the area Saturday night into Sunday. Most of the area should see precipitation as this initial wave moves through, though could see a bit of a rain shadow off the Olympics as flow aloft becomes more zonal. Highest precipitation amounts expected in the Olympics and Cascades. Snow levels will initially start above pass levels but will drop steadily on Sunday into Sunday night down to around 3,000 feet by Sunday evening. Higher passes will likely see at least a few inches of accumulation by then so those who are getting a jump start on holiday travel should keep an eye on the forecast. As gradients tighten, could also see some breezy winds across the area, though it doesn't look like anything impactful at this point.

A second system follows quickly on the heels of Sunday's system for Monday into Tuesday. Models and their ensembles are in rather good agreement through this point. This will bring another round of precipitation for the area and an additional shot of cooler air. Current forecast suggests snow levels down to around 2000 feet. Again those with holiday travel plans should keep an eye on the forecast as details evolve.

Past Tuesday, deterministic model solutions diverge and ensemble solutions provide a range of possibilities. There likely will be additional systems but exact track remains unseen. Worth noting that latest deterministic runs and ensembles do hint at perhaps a short break in the action for Thanksgiving Day but solutions have been jumping around so hard to put much stock in the details this far out. For now have kept with a blended approach which suggests general troughiness and broad-brushed POPs for much of the period. Regardless of precipitation amounts and snow level, ensembles do agree on additional cooler air filtering into Western Washington with the possibility of highs in the upper 30s to low 40s by mid to late week. Will certainly be keeping on eye on the trends as we head into the holiday week.

CEO

AVIATION. An upper ridge over the area will shift inland later today. A dry upper trough will cross the area tonight. The flow aloft will be westerly. At the surface, weak offshore flow will switch to weak onshore tonight. The air mass is stable with areas of low level moisture over the central and south interior.

Areas of low clouds and fog over the central and south Puget Sound area will burn off this morning or early this afternoon with mostly clear skies after that. Areas of low clouds and fog should reform again tonight - probably a bit more extensive and a bit more low clouds versus fog with weak onshore flow.

KSEA . Shallow dense fog should burn off later this morning with mostly clear skies after that. Low clouds and fog are likely again Friday morning. Northerly wind 4-8 knots will becoming light southerly tonight. Schneider

MARINE. Weak offshore flow will switch to weak onshore tonight and Friday. A frontal system will cross the area Saturday and Saturday night with advisory strength southerly winds for the Coastal Waters. There should be a good westerly push down the Strait behind the front Saturday night/Sunday morning.

Moderate onshore flow will continue on Sunday. A second frontal system will drop down from the northwest Sunday night and Monday.

In addition, west swell over the Coastal Waters will build to 10+ feet tonight and Friday and remain mostly in the 10-15 foot range through the weekend. Schneider

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.
