Area Forecast Discussion National Weather Service Seattle WA 823 PM PST Fri Dec 1 2023

SYNOPSIS
A series of strong weather systems will maintain active weather across the Pacific Northwest for much of the week ahead. Heavy precipitation and gusty winds develop overnight through early Saturday, maintaining hazardous winter driving conditions over the Cascade passes. This is followed by a pair of atmospheric rivers that impact the region through early next week. This will also lead to increased risk of river flooding across the region, especially Monday and Tuesday with much higher snow levels bringing widespread rain.

SHORT TERM /TONIGHT THROUGH MONDAY/
Areas of light rain and mountain snow are moving across Western Washington this evening in association with a slightly stronger shortwave trough and associated surface low and attendant cold/warm fronts. These features will move eastward along the Canadian border into Saturday morning, maintaining a wet and breezy conditions. A with a few lightning strikes having been observed late this afternoon and evening with isolated thunderstorm activity along the immediate coast. Some small hail and gusty winds cannot be entirely ruled out with additional thunderstorms towards the coast through tonight, though nothing severe.

24-hour snowfall estimates from earlier this afternoon included around 7 inches at Snoqualmie Pass and 10 inches at Stevens, with over a foot at Paradise on Mount Rainier. WSDOT webcams images continue to show snow-covered roadways, more so at Stevens and White Passes. The current Winter Storm Warnings for the Cascades and the Winter Weather Advisory for the Olympics both remain in effect with no changes, though rising snow levels overnight will keep the highest snow amounts above around 3,000 feet as the steadier precipitation arrives. An additional round of heavier snow in the mountains will move in through early Saturday.

Meanwhile, Wind Advisories also continue for all of the lowlands with a burst of strong southerly winds expected ahead of the aforementioned cold front. Probabilities for wind gusts exceeding 45 mph are around 40-50% for most of the lowlands, slightly higher for locations closer to the coast and inner waters.

Heading into Sunday, snow levels begin to really rise with the atmospheric river moving into the region. Guidance today has shifted the axis of strongest moisture transport and, accordingly, the highest QPF to the south from the previous cycle and the forecast has been updated accordingly. This system will bring another round of heavy rain, including rain on the newly fallen snow, which will result in enhanced flows on local rivers and the potential for river flooding. See the hydrology section for additional details on the flood watch and this threat.

LONG TERM /TUESDAY THROUGH FRIDAY/
This next system likely pushes into the region by late Monday night and into Tuesday. With abundant moisture transport and very high snow levels, the hydrologic concerns remain elevated through Tuesday and Wednesday.
Again, more details follow in the hydrology section below, but the impact of rain falling on snow will likely only further enhance the potential for flooding next week. The forecast will remain very sensitive to minor changes in QPF, so continue to closely monitor the forecast in the coming days. Items of concern all dependent on where and how quickly the heaviest rain falls with this third and strongest atmospheric river will be river flooding, the threat for avalanches, and burn scar landslides and/or debris flows.

Davis/Cullen

AVIATION
Another round of showers ahead of a surface trough has begun to make its way into Western Washington. A few lightning strikes remain possible this evening, especially near KHQM. Ceilings are bouncing around a bit but are generally MVFR. Ceilings should remain MVFR with the rain showers, though may occasionally dip to IFR at times in heavier showers or in reduced visibility. Rain should last through Saturday morning, then ceilings have a chance to lift and break to low-VFR Saturday afternoon before the next frontal system approaches the region.

Winds are beginning to pick up and will remain southwesterly at around 15-25 kt, with gusts up to 30-40 kt possible through the overnight hours. Winds will ease somewhat beginning Saturday morning, to 10-20 kt gusting to 20-25 kt. Winds will further calm down below 10 kt Saturday evening.

KSEA...Ceilings primarily MVFR, becoming IFR at times, with southwesterly winds 15 kt gusting to 25 kt. On and off rain showers will continue through around 15Z Saturday, as well as winds up to 20 kt gusting up to 35 kt. MVFR ceilings expected to continue through late Saturday morning, ceilings may raise and break into low VFR.
Winds remain southwesterly and above 10 kt through Saturday evening.

MARINE
Winds are beginning to pick up over the coastal and inland waters of Western Washington. Small Craft Advisories will be converted into Gale Warnings, and these warnings will go into effect for all waters later tonight through Saturday morning. Strong winds are expected to linger in the Central and Eastern Strait of Juan de Fuca, therefore, those warnings will drop off Saturday afternoon.
Following, Small Craft Advisories will remain in effect for the coastal waters and Grays Harbor Bar for elevated seas. Additional systems will require headlines Sunday and going into next week.

Seas around 12 to 14 ft at 11 s will build to around 16 to 18 ft early Saturday. Seas will remain above 10 feet until further notice, with additional wave height peaks at 16 ft to near 20 ft expected on Monday and Wednesday. Periods of 16-18 s on Wednesday may encroach on high surf criteria if waves maintain this height to the shore.

HYDROLOGY
A series of weather systems will move through Western Washington over the weekend and through the first half of next week, bringing multiple rounds of rain and periods of mountain snow to the region. A Flood Watch remains in effect for the area from Saturday evening through late Wednesday night. While periods of heavy snow are forecast for the mountains through Saturday, expect warmer and wetter systems to move into the area Sunday through Tuesday. As a result, snow levels will rise rapidly from 2500 to 3500 feet to 5500 to 6500 feet on Sunday morning, before peaking at 8000 to 9000 feet by Monday night. 72 hour precipitation totals from Sunday morning to Wednesday morning generally range from 10 inches in the higher elevations of the Olympics and Cascades, 6-8 inches for the foothills, 2-4 inches for the interior lowlands, and 4-6 inches for the coast. The combination of heavy precipitation and rising snow levels will most likely result in river flooding on many rivers across western Washington. At this point, moderate flooding is possible on some of the bigger rivers like the Snoqualmie and Skagit as well as the lower reaches of the Chehalis beginning Tuesday. An important point to note, however, is that while flooding looks likely across the region, there remains a degree of uncertainty in the scope and extent due to timing of the snow to rain switchover in the high elevations and uncertainty in the locations of the heaviest bands of precipitation. Thus, it will be important to stay up to date on the latest forecast developments over the weekend.

In addition to the river flooding, burn scars in the Cascades will have to be monitored with the heavy precipitation forecast. Elevated risks of landslide and debris flow threats will be possible at times next week.
