Area Forecast Discussion National Weather Service Seattle WA 855 PM PST Sat Dec 9 2023

UPDATE
Widespread lowland rain and mountain snow is ongoing across the CWA this evening. PWATs around 1.10-1.30" just off the WA/OR coast are streaming inland as this atmospheric river is slated to persist overnight into Sunday. As such, continued rainfall along with recent precipitation earlier in the week will increase soil instability, leading to an increased threat of landslides. Other than this tid bit, the inherited forecast remains consistent as the previous discussion is below along with an updated marine/aviation section.



SYNOPSIS
A frontal system will continue to move through the region into Sunday for moderate to heavy rain, mountain snow, and areas of gusty winds. A quieter period of weather is expected early next week as upper level ridging builds into the area.



SHORT TERM /TONIGHT THROUGH TUESDAY/
A strong Pacific frontal system has entered W WA this afternoon and will continue to bring moderate to heavy rain at times in the lowlands and snow in the mountains. With some cooler air being trapped along the Hood Canal and areas in Kitsap county and Western Whatcom, precipitation rates have been heavy enough to bring the snow level down in these areas, in result, there have been some wet snow accumulations of around 1 to 2 inches this afternoon. A winter weather advisory remains for Hood Canal until 4PM. Temperatures will continue to rise into this afternoon and will start to limit snowfall. As the warm front passes through, expect warmer temperatures and higher snow levels throughout the region. Winds have also increased along the coast, areas in the North Interior especially at Whidbey Island. A wind advisory still remains in place for these areas, with the coastal winds tapering off this evening, while the winds in the interior will continue to remain gusty until late tonight.

Snow levels in the mountains this afternoon have been around 1500 to 2500 feet, and will rise to around 3500 to 5000 feet by late this evening. Precipitation has started off as snow earlier this afternoon, especially at pass elevations, and will turn into rain once the snow levels rise later later this evening. When this transition happens, it will be a close call on the precipitation type during this time. Easterly surface gradients will help a thin layer of cooler air stay at the surface, especially at the passes. Therefore, there still remains a slight chance (10-20%) of freezing rain at Snoqualmie and Stevens pass overnight into Sunday morning while that transition to rain to snow happens. A winter storm warning remains in effect for the Central Cascades, while a Winter Weather Advisory continues for the North and Southern Cascade Zones.

Snow levels will be around 6500 to 7000 feet by Sunday morning, with moderate to heavy rain beginning to taper by late Sunday afternoon, as a trailing cold front pushes through the area. Snow levels look to dip slightly but remain above 5000 feet through the day, keeping the threat of minor river flooding going in a couple of locations and the increased risk for landslides. See the hydrology section for more details regarding this. High temps through the area will in the low 50s, with lows in the upper 30s.

Weak troughing continues to influences Western Washington through Monday, with just some light showers through the area and high temperatures in the upper 40s to lower 50s. Shower chances look to decrease into Tuesday as a weak upper level ridge builds offshore with high temps not fluctuating much.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
High pressure looks to build over the Pacific Northwest into early next week for a break in the weather, before a weak front looks to sneak into the area by early Thursday for some increased precipitation chances.
Clusters are not agreeing on a solution going into the weekend, with some ensemble guidance leaning towards a ridge building into Friday and Saturday. Lows will be cooler in the 30s with highs in the 40s for next weekend.

AVIATION
Strong westerly flow aloft and a moist air mass with a warm front across Western Washington. The trailing cold front will move onshore during the afternoon on Sunday. IFR to LIFR ceilings with moderate to locally heavy precipitation. Precipitation should ease by Sunday afternoon with low ceilings likely to continue. Gusty S/SE surface winds along the coast and interior areas north of KPAE have begun to ease.

KSEA...MVFR ceilings will lower to IFR tonight with moderate to occasionally heavy rain. Low level wind shear potential continues with southerly winds at 2000 feet around 40 knots veering southwesterly late. Surface winds S/SE generally 4 to 8 knots.



MARINE
Headlines remain in place with gales continuing across coastal waters and northern portions of the inland waters ahead of a warm front that will lift northward across the area tonight. Winds will begin to ease tonight as a E/SE oriented pressure gradient relaxes. A cold front will drag onshore by Sunday afternoon followed by a building surface ridge over the coastal waters on Monday. The ridge will shift inland on Tuesday allowing for increasing offshore flow. A weakening front will reach the waters late Wednesday into Thursday. Hazardous seas of 13 to 17 feet tonight will gradually subside on Sunday before falling back below 10 feet early in the coming week. Another swell train arriving after midweek could approach 10 feet once again. 27

HYDROLOGY
A brief lull in activity continues early this morning before the next frontal system brings another round of rain and mountain snow later today. Snow levels start off between 1000 and 2000 feet then rise to 5500 to near 7000 feet tonight.
Forecast rainfall totals are similar to the last run with mountain locations ranging from 2 to 3 inches with local higher amounts.

Antecedent conditions of high soil moisture and high river levels are favorable for the potential of some new flooding, and also the increased risk of landslides. The forecast amount of rain with higher snow level will drive significant river rises in a few locations but for most areas it will not result in flooding. The most likely river to flood is the Skokomish where a flood watch is out for Mason County. There is a low chance of flooding in additional areas, mainly for the Snoqualmie River and the Chehalis River Basins. A Flood Potential Outlook remains out for King, Thurston, Lewis, and Grays Harbor counties. JBB/Maz
