Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working.

Area Forecast Discussion National Weather Service Seattle WA 251 AM PST Sun Dec 15 2019
SYNOPSIS. Scattered showers through this morning. High pressure will build over the area Monday and Tuesday but a frontal system may brush western and northern portions of the area. Wetter weather is expected by middle to the end of this week as multiple systems move through.
SHORT TERM /TODAY THROUGH TUESDAY/. Scattered showers across portions of the central and northern Puget Sound this morning as a shortwave trough slides through WA. Small hail reported as well in spots across King County with cool air aloft. Showers should diminish early this afternoon for the interior with relatively dry conditions by this evening into tonight as an upper level ridge begins to build offshore. Snow showers through today for the Passes with light accumulations, under an inch or two possible, with the heaviest of bands. Temperatures today will be in the mid 40s.
The upper level ridge will build over the area Monday into Tuesday, however a warm front moving north across the offshore waters will bring the chance for showers especially for the Olympic Peninsula and North Interior Monday afternoon into Tuesday. Some sunshine will be possible in spots later on Monday with mostly cloudy skies by Tuesday as the system approaches. Temperatures will be in the mid to upper 40s. JD
LONG TERM /WEDNESDAY THROUGH SATURDAY/. The middle to end of this week will be rather active for Western Washington. The first system will move through Wednesday with a series of shortwaves through Saturday as troughing develops offshore. Thursday into Saturday appears the most active on guidance with lowland rain and mountain snow. Breezy, and perhaps windy, conditions are expected as well with the series of systems late week. Temperatures will be a bit above normal in the upper 40s. JD
AVIATION. An upper level disturbance will maintain scattered showers today, mostly over the interior and Cascades. The flow aloft is NW. Ceilings are generally MVFR to IFR this morning with patchy fog possible. We should see improving conditions this afternoon as the upper level disturbance exits and pushes east of the Cascades (while high pressure nudges in from the west). A weak warm front will clip the area early Monday for a chance of rain.
KSEA . Expect showers in the vicinity today with possible MVFR to IFR conditions this morning. S winds at the surface to 5 kt. Ceilings will gradually lift and improve late this afternoon to VFR. 33
MARINE. Radar imagery early this morning reveals another round of scattered showers affecting some of the waters early this morning. Most of the radar echoes are seen from the Northern Inland Waters into the eastern Strait of Juan de Fuca and into Puget Sound. A few pin-prick showers exists offshore the Washington Coast as well. Should see scattered activity continue through at least the first half of the day today as a weak shortwave progresses north to south across the area. Patchy fog developed earlier in the evening in the vicinity of the interior waters and expect patchy activity to continue near these waters into much of the morning hours. Shower and fog activity may reduce visibility over the waters at times.
Winds and seas remain light this morning and this trend will continue through much of the afternoon. Took a while for seas offshore to ease yesterday but observations finally indicated a drop to the 6-8ft range late last evening. These calm conditions will unfortunately not last long. A look at the pattern upstream reveals a frontal system across the Pacific, and this system will be marching E/NE thru the day today. The warm frontal portion of it should approach the vicinity of the Coastal Waters later today/tonight. Winds in its vicinity will pick up quickly to small craft advisory levels this evening. Small craft winds will eventually spread over the interior waters early Monday morning. Have spared Puget Sound and the central Strait of Juan de Fuca from these winds, tho Puget Sound is worth keeping an eye on. These winds appear to remain elevated for the foreseeable future and these headlines will likely need to be extended further in time during future forecast updates. The pattern looks to remain quite active this week, with even windier conditions possible late in the week within possible atmospheric river event.

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 are not likely to be high enough to put Western Washington into a river flooding situation.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
