Area Forecast Discussion National Weather Service Seattle WA 244 AM PST Fri Dec 6 2019

SYNOPSIS. A weak front will spread light rain across Western Washington this evening through Saturday morning. The low will move east of the area Saturday night. An upper level ridge will build offshore Sunday for dry weather through early Tuesday. The next system should slide through later on Tuesday.

SHORT TERM /TODAY THROUGH SUNDAY/. Radar as of 2AM shows areas of light rain showers across portions of the northern Olympic Peninsula and North Interior as a warm front lifts through. Dry weather elsewhere with patchy low clouds and fog in spots. An area of low pressure well offshore will slide east through today. A weak front with this system will move onshore later today into tonight with light rain across Western Washington. The interior will stay generally dry through this afternoon as the rain moves onshore with showers overnight into Saturday morning. Snow levels with this system will be around 4500 feet, with at least a rain/snow mix and an inch or two possible at Stevens Pass. Showers will be in the area Saturday afternoon before diminishing Saturday night as the system moves east.

An upper level ridge will build offshore Sunday morning with drier weather expected along with areas of morning fog. Partly sunny skies expected by the afternoon. Temperatures into the weekend will be in the upper 40s to mid 50s across Western Washington. JD

LONG TERM /MONDAY THROUGH THURSDAY/. The upper level ridge will build over the area on Monday. Areas of fog expected on Monday with the ridge with mostly sunny conditions by afternoon. The ridge will slide east on Tuesday as the next frontal system approaches. The first system will move through later Tuesday into Tuesday night although it may weaken as it does slide across the area. Guidance does show a more substantial system may move through by Thursday with ensembles suggesting a more active pattern later next week. JD

AVIATION. An approaching upper level low will shift flow aloft from westerly to southwesterly this morning and it will remain from the SW for the remainder of the day. Surface flow remains offshore . easterly to southeasterly over W WA.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
