Area Forecast Discussion National Weather Service Seattle WA 830 PM PDT Sat Mar 28 2020

UPDATE. Light rain this evening across portions of Western Washington as a weak front moves through the area tonight into early Sunday. Snow levels around 4000-4500 feet tonight and drop to 3500 feet by late Sunday morning. A few showers around Sunday afternoon, though most places generally drier. A strong system will move through Sunday night into Monday for mountain snow and locally windy conditions.

SYNOPSIS. A weak front will arrive tonight and Sunday. A strong cold front will reach Western Washington around daybreak Monday. The snow level in the mountains will fall as a rather cool air mass drops over the region Monday and Tuesday.

SHORT TERM /TONIGHT THROUGH TUESDAY/. A weak front will bring some areas of light rain to the area tonight and Sunday--not a lot of change from today. Colder air will drop down over the northeast Pacific for the first part of the week with a significant upper trough. A quick cold front around daybreak Monday will be followed by a cool showery air mass. It will be blustery as well at times, mainly with the front Monday morning. The snow level will fall below the passes with wintry travel at times in the mountains. The unstable air might give the area a few tstms and, for now, that is in the forecast for Monday afternoon and again Tuesday afternoon.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. A cool air mass will linger into Wednesday but shower activity should be decreasing. Upper ridging for the latter part of the week will allow temps to warm into the end of the week. It is not clear whether it will be dry and there are some low pops in the forecast. The 12z GFS is actually quite wet Thursday night and Friday and the ECMWF has a frontal system arriving for Friday night and Saturday, so we may yet see the forecast trend toward rainy weather in the extended.

AVIATION. Southwesterly flow aloft as an upper level trough moves through. The weak front will move through the area tonight with light rain at times. MVFR cigs for most through Sunday afternoon with IFR in spots around the Puget Sound. Southerly surface winds 7 to 14 knots into Sunday with stronger southerly winds Sunday night into Monday morning as a system moves through.

KSEA . MVFR into Sunday afternoon with light rain at times, especially tonight into early Sunday morning. Southerly winds 7 to 14 knots with gusts to 20 knots possible.

MARINE. A weak front crossing the waters through tonight for Small Craft Advisories for most waters. A stronger system will move through late Sunday into early Monday with increasing southerly winds Sunday evening. Gales possible with this system for the coast, eastern Strait of Juan de Fuca, and northern inland waters. Small craft advisories elsewhere. Winds will subside late Monday into Tuesday with steep seas into mid-week over the coastal waters and lighter winds. JD

HYDROLOGY. River flooding is unlikely for the next 7 days.

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.
