Area Forecast Discussion National Weather Service Seattle WA 208 PM PST Sun Dec 15 2019

SYNOPSIS. Weak high pressure aloft will build over the area Monday and Tuesday. A warm front will brush western and northern portions of the area Monday with some light rain. A broad upper level trough will develop over the northeast Pacific by midweek with a series of potent systems reaching the area into next weekend.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/. Scattered showers will gradually dissipate over the area this evening as weak upper level ridging starts to build into the area. Still a lot of low level moisture continues to linger around the region. With light surface winds, patchy fog is likely to form in the more fog prone valleys overnight. Higher level clouds associated with a weak warm front offshore are already close to the coast and will spread into the region later tonight. Some light rain associated with the warm front is expected to reach coastal areas and perhaps the north interior Monday. The remainder of the area should remain generally dry Monday and Tuesday. The air mass dries out somewhat on Tuesday as cross-Cascade easterly flow picks up. This should help limit fog coverage and give some areas at least some partial sunshine. A broad upper trough will deepen over the northeast Pacific Tuesday night and Wednesday with the first of a series of systems spreading widespread rain and mountain snow across the area on Wednesday.

LONG TERM /THURSDAY THROUGH SUNDAY/. The extended forecast period continues to look like an active string of weather for the region. Deterministic model runs funnel a fairly significant stream of moisture into the region. Snow levels look to remain relatively low through much of period and this translates to some significant snowfall in the mountains in the run-up to the Christmas holiday period. 7 day precipitation anomalies of both the GFS and Euro show some positive values of 1 to 3 inches for the region. This is leaning toward a decidedly wetter period from what we've seen recently. 27

AVIATION. A weak upper trough will be replaced by an upper ridge through Monday. NW flow aloft. Isolated showers should come to an end this evening. There will again be patches of fog and low clouds tonight. A warm front will clip the area on Monday for some areas of light rain on the coast in the morning.

KSEA . Skies have not cleared much today around Seattle so the moist and stabilizing air mass will probably lead to some low clouds tonight. Mid and high clouds from a warm front brushing the area later tonight will help to keep radiational cooling from letting much fog set up.

MARINE. A warm front will clip the area on Monday. After the warm front brushes by gradients will become more easterly on Tuesday. Two or three frontal systems will affect the area Wed-Sat.

HYDROLOGY. There are no flooding concerns through the first half of this week. The latter part of this week will be wet, but snow levels will be relatively low. There will be some rises on the rivers. The Skokomish in particular will bear some watching.

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.
