Area Forecast Discussion National Weather Service Seattle WA 824 PM PST Sat Jan 18 2020

SYNOPSIS. Moist southwest flow aloft will direct a disorganized weather system into Western Washington this evening. A frontal system moving into British Columbia on Sunday will brush Western Washington as a weak upper ridge builds. A weak cold front will reach the area on Monday. Additional weather systems are likely next week with periods of rain and breezy conditions at times.

SHORT TERM /TONIGHT THROUGH TUESDAY/. Scattered showers will linger across the area tonight in the wake of a front. A weak warm front lifting north through the area will bring a somewhat better chance of light rain on Sunday. Sunday night will be largely dry then a weakening cold front will bring spotty light rain rain on Monday. A stronger frontal system will affect the area Monday night and Tuesday.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Previous discussion . Weather systems will give periods of rain and sometimes breezy conditions to Western Washington through the end of next week. Snow levels will be a notch higher than they should be this time of year and the frontal system around Thursday warms 850mb temps to around +4c so we may yet see the Skokomish River in Mason county flood about that time.

AVIATION. Southwest or west flow aloft across the region with the remnants of a weak front remaining across the region. Expect a mostly VFR cloud deck, though pockets of MVFR conditions will continue. This is especially the case across the western portions of the forecast area where rain showers are most persistent.

KSEA . Expect mostly VFR conditions in showers behind a front and southerly surface winds continuing.

MARINE. A weak warm front will lift north through area on Sunday. A weakening cold front will move through the area on Monday followed rapidly by a stronger frontal system Monday night and Tuesday. Gales are possible for some waters with the Monday night/Tuesday system. The weather will stay active Wednesday and Thursday with additional weather systems affecting the area.

West to southwest swell has built to 16-18 over the Coastal Waters and West Entrance Strait of Juan de Fuca this evening which is a few feet higher than earlier expected. At this point, it looks like swell will remain below 20 feet this evening but this will need to be watched. The large swell should begin to subside later tonight.

HYDROLOGY. Rainfall will not be particularly heavy into the first part of the week, but the Olympic Rivers in particular will start rising. Out around Thursday of next week there might be a frontal system warm and wet enough to drive the Skokomish up above flood stage.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ .

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.
