Area Forecast Discussion National Weather Service Seattle WA 301 PM PST Tue Dec 7 2021

SYNOPSIS. Colder and wetter weather returns tomorrow. Multiple weather systems will be making their way through the Western Washington area in the next seven days. Each system is expected to bring lowland rain, mountain snow and breezy to windy conditions. Towards the end of the week there is the potential for snow levels to drop down low enough for the lower elevations to see some flakes falling.

SHORT TERM /TONIGHT THROUGH FRIDAY/. The first in the most recent series of the weather systems will begin moving through the area late tonight/early Wednesday. This system will bring mostly light rain to the lowlands as well as a return to high temperatures in the 40s. However, this system is expected to give the mountains a healthy dose of snow through Thursday. Snow levels will be dropping down to 2000-2500 feet by Wednesday morning with accumulations at both Stevens and Snoqualmie Pass to be 12-18 inches. These high accumulations are a result of this synoptic system being enhanced by the Puget Sound Convergence Zone. High resolution models are pretty consistent with the PSCZ settling over I-90, which will give Snoqualmie Pass the high snow earner for this event. Due to the PSCZ enhancement, we are expecting snow fall rates to be 1-2 inches per hour at times. As a result, a Winter Storm Warning has been issued for above 2000 feet in the Cascades. This is not to say that the Olympics will not receive a decent amount of snow. They too are expecting 8-12 inches, but because of the lower snow fall rates they have a Winter Weather Advisory.

Additionally, there is the slight chance that the coast and the coastal waters could see some thunderstorms Thursday as a shortwave disturbance moves through the area. Confidence is slightly higher than it was last night as guidance is showing colder temperature aloft, which will increase the amount of instability.

And finally, southwesterly to westerly winds will increase overnight across the region, yielding breezy to gusty conditions through Wednesday afternoon. This, coupled with high tides will lead to minor tidal overflow near Port Townsend and along the San Juan coast tomorrow morning. Tides will fall on Wednesday afternoon.

This first system will fully make its way out of the area Thursday. Giving us a short break before the next system makes its approach into the area late Friday.

Butwin

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. We are expecting a stronger system to be making its way through the area starting late Friday and continuing into the weekend. Unlike the stronger weather systems we have seen last month this system is originating out of the Gulf of Alaska, which means that it will be a colder system (compared to what we saw in November). As a result snow levels are expected to be in the 2500-3500 range during the event. Expected snow storm totals will continue to fluctuate as their is still some uncertainty in the track of the storm. That said, ensemble guidance shows that the passes have a 60-70% chance of seeing at least a foot of snow, with the potential to see greater than 2 feet at the passes. If you are planning on traveling through the mountains this weekend stay up to date on weather and road conditions.

This system is also expected to bring widespread strong southerly winds across the region Friday night into Saturday. Current model guidance suggest widespread wind gusts of at least 40 mph across Western Washington by Saturday morning. Recent NBM 10% probabilistic guidance has been supporting this, with potential for gusts approaching 60 mph on the outer coast and along the Whatcom/Skagit County Coast line Saturday morning. EPS guidance is also hinting at the potential for strong gusts to that magnitude in the aforementioned areas, while the 12Z GEFs members are notably weaker. With ensemble cluster analysis starting to converge on the pattern (shortwave ridge axis exiting W WA ahead of a potent, digging upper low), confidence is increasing in the potential for wind impacts in addition to those from heavy snow with this system.

Conditions are expected to improve by Sunday, but some areas along the coast an in the North Interior could still be seeing some breezy conditions. Showers will likely continue through the day.

Conditions will remain wet and cool for the remainder of the forecast period.

Butwin

AVIATION. Weak isentropic lift continues to generate weak showers that are producing light drizzle across the region, affecting CIGs and vsbys at terminals across the region this afternoon. This will persist through this evening before an approaching frontal system increases winds and helps CIGs to mix out to above 1000 feet this evening into tonight. Rain will spread across the region tonight, with most terminals seeing periodic reductions in vsbys and CIGs generally remaining between 1500-2500 feet. Southwesterly to westerly winds will prevail at speeds between 10-15 kts and gusts 20- 25 kts.

KSEA . Low stratus and light drizzle will persist through this evening, with CIGs generally ranging from 500 to 1000 feet through the evening and CIGs fluctuating between 3-6 SM between areas of drizzle. Southwesterly winds will increase this evening, generally after 06Z with the approach of another front. Sustained winds 10 to 15 kts with gusts 20 to 25 kts. Periods of SHRA will affect the terminal after 06Z and will continue through much of Wednesday, bringing periodic reductions in vsbys to the terminal. Some hi-res guidance shows the potential for a convergence zone in the vicinity of the terminal starting Wednesday morning and potentially persisting into the afternoon.

Pullin

MARINE. Winds increase this evening and tonight ahead of the next front. Expect a fairly strong push of west/northwest winds behind the front, with high end advisory strength winds over the coastal waters tonight into Wednesday. A brief gale is expected in the Central and Eastern Strait of Juan de Fuca late tonight into Wednesday morning. Advisory level winds will spread into Puget Sound and portions of the Northern Inland waters late tonight through Wednesday morning, with advisory level winds persisting through the Central and Eastern Strait, as well as Admiralty Inlet through Wednesday night. Winds will ease, but building seas over the coastal waters will maintain advisories longer with seas 10-13 ft through Thursday night.

After a bit of a lull in the winds, a much stronger system likely approaches late Friday into Saturday, for much better chances for gales across most waters as well as some potential for seas to build to 15 feet or higher.

HYDROLOGY. No river flooding is expected in the next 7 days.
