Area Forecast Discussion National Weather Service Seattle WA 936 AM PST Fri Dec 13 2019

UPDATE. The inherited forecast remains largely on track this morning. As expected, precipitation has become more sparse in coverage at this hour, with intermittent rain showers in portions of the lowlands and light snow showers in portions of the Cascades. Significant accumulations are not expected to occur with this activity, thus the Winter Storm Warning for the Cascades will expire at the top of the hour. There is evidence on the latest visible sat of some convection developing offshore and hi-res guidance continues to indicate 150-300 J/Kg CAPE across portions of Western Washington by this afternoon. This will support shower development and perhaps isolated thunder, thus continued to keep thunder in the forecast through this evening.

AVIATION. Westerly flow aloft continues today as a broad upper trough remains over the region. The air mass is moist and somewhat unstable. The flow aloft will turn northwesterly tonight as weak upper ridging moves into the coastal waters. The low level flow is weak southerly and will become light and variable this afternoon. A mix of VFR and MVFR ceilings with scattered showers will continue into the afternoon. Low end MVFR ceilings are expected to become widespread tonight as the air mass remains moist and low level flow is weak.

KSEA . Expecting generally VFR ceilings in the 040-060 range today dropping to MVFR in and around passing shower activity. MVFR ceilings become the dominant condition tonight from about 03Z onward. Surface winds S-SW 10 knots or less.

MARINE. The main marine related hazard that remains in place today and into Saturday will be hazardous seas across the coastal waters. Swells in the 17-19 ft range are possible this morning and are expected to gradually subside to 14-16 ft range by the evening. Swells will also be hazardous in the western Strait of Juan de Fuca.

Winds not expected to be a concern into the weekend. They will gradually turn more offshore early next week as surface high pressure gets more established east of the Cascades.

HYDROLOGY. There are no flooding concerns at this time. Relatively low snow levels and limited precipitation amounts will result in little or no impacts on area rivers.

PREV DISCUSSION. /issued 228 AM PST Fri Dec 13 2019/

SYNOPSIS . Heavy snow showers will taper off in the Cascades today. Expect scattered showers with a possible thunderstorm in the lowlands. A ridge will bring quieter weather this weekend and into early next week. The weather pattern may turn more active late next week.

SHORT TERM /TODAY THROUGH SUNDAY/ . Heavy snow continues across the west slopes of the Cascades this morning - a Winter Storm Warning remains in effect. Snow levels are around 3500 feet with heavy snow impacting the higher passes like Stevens Pass and White Pass. Snoqualmie Pass is seeing a rain/snow mix but they still managed to record around 9 inches. Showers will taper off late this morning and afternoon with coverage becoming more scattered. There is still a possibility of snow showers in the mountains but heavy accumulations are not expected.

Meanwhile, the air mass over western WA will remain cool and slightly unstable across the region. Offshore we are seeing convective-type cells that will drift inland through the day and isolated thunderstorms cannot be ruled out. Otherwise, we may see a few breaks in the clouds for partly sunny skies. Expect highs in the 40s this afternoon.

Western WA will lie under NW flow this weekend as an upper level ridge builds offshore. Models show just isolated showers over the area as a weak disturbance moves down from B.C. But overall we will see less active weather compared to the last few days. 33

LONG TERM /MONDAY THROUGH THURSDAY/ . An upper level ridge will shift inland early next week, pushing the bulk of moisture north into B.C. This ridge may linger over the region through around midweek before it starts to weaken/flatten. This then opens the door for a stronger and wetter Pacific frontal system slated for next Thursday or Friday. This may result in another round of heavy snow in the mountains. 33

AVIATION . Westerly flow aloft turning more northwesterly this evening and remaining that way into Saturday. Surface flow will ease with gusts winding down and wind speeds easing to generally 5 to 10 kts from mid to late morning and through the remainder of the TAF period. Wind direction will remain south to southwest.

Cigs a mixed bag out there this morning as showers persist over the area. Most locations reporting VFR to MVFR conditions in place although some showers are dragging conditions down into IFR. These IFR conditions are fairly isolated though. Should start to see conditions improve by late morning/early afternoon with widespread VFR conditions in place over W WA by early afternoon. Plenty of low level moisture will allow for conditions to deteriorate this evening and tonight with widespread MVFR to some isolated patches of IFR returning to finish off the TAF period.

KSEA . Lingering showers will still be a possibility as moisture lingers from exiting system . but coverage still expected to diminish through the day today. Cigs this morning will flip back and forth between VFR and MVFR Given abundant low level moisture. will lean more toward MVFR for TAF in the morning but will see improvement to solid VFR between 18-20Z today. MVFR conditions will likely return tonight with aforementioned low level moisture still in place Winds south 8-12 kts this morning. easing to 5-10 kts by this afternoon. SMR

MARINE . Another frontal system passed across western Washington, bringing with another round of widespread rainfall over the waters. Recent radar imagery suggests the rainfall has become more scattered, tho it does continue to affect some of the waters, particularly the Strait and the Northern Inland Waters. Scattered showers will continue through the morning hours today, gradually decreasing in coverage with time through the afternoon.

Winds have been easing across the waters over the last 12 hours and this trend will continue. Do not see any areas that will meet or exceed small craft advisory criteria for wind over the next couple of days. The main marine related hazard that remain in place today and into the first half of Saturday will be hazardous seas across the coastal waters. Swells in the 17-19ft range are possible this morning and are expected to gradually subside a few feet down into 14-16 ft range by the evening. Swells will also be hazardous in the western Strait of Juan de Fuca, tho will remain a few feet below the coastal waters. Seas will continue to subside into Saturday but look to remain hazardous through most of the morning.

With the highest swells expected this morning (Friday), have left High Surf Advisory in place thru 18z (10am) along the Washington Coast. However, make note that seas will still be rough into Saturday.

Kovacik

HYDROLOGY . There are no flooding concerns at this time. Relatively low snow levels and limited precipitation amounts will result in little or no impacts on area rivers.

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.
