Area Forecast Discussion . UPDATED National Weather Service Seattle WA 509 AM PST Mon Nov 30 2020

UPDATE /This morning/. Quick update this morning to extend the Wind Advisory for the San Juan Islands, western Whatcom, and western Skagit counties through 9 AM. Gusts to advisory strength will likely linger for the next hour or two, before easing behind the front later this morning. Given that the winds are just peaking at Bellingham airport and near Ferndale, opted to extend for a few more hours.

SYNOPSIS. A strong cold front is crossing Western Washington this morning, bringing gusty winds, and heavy lowland rain and mountain snow. Some showers linger today, especially in the Cascades, as an upper trough moves through. High pressure begins to build quickly over the Pacific Northwest on Tuesday, setting the stage for a shift to a dry pattern that will last through much of the week.

SHORT TERM /TODAY THROUGH WEDNESDAY/. The strong cold front continues to advance inland this morning as expected, with heavy rain pushing through the Olympic Peninsula and moving into the Puget Sound region now (around 3 AM). Expect the precipitation band to continue to push east, likely reaching the Cascades by around 6 AM. Strong southerly or southeasterly winds continue ahead of the front, with gusts generally in the 40 to 50 mph range so far. Hoquiam just reported a peak gust of 45 mph, while an observation site on Lopez Island recorded a gust to 59 mph. Also a somewhat mild morning for those locations getting in on the warm advection ahead of the front - Pierce County Airport (Thun Field) in Puyallup warmed from 39 degrees to 52 degrees over the last hour as the stronger southerlies arrived! Meanwhile, temperatures in the more wind sheltered areas remain cooler, in the lower 30s.

The current timing on the Wind Advisory remains on track, so no updates to that are planned this morning - the segment including San Juan, Whatcom, and Skagit counties is in effect through 5 AM. The strong southerly winds will ease behind the front and shift to become westerly, with a stronger west surge through the Strait of Juan de Fuca and around the Admiralty Inlet area this afternoon. Expect breezy westerly winds to continue into the afternoon, before easing overnight

Meanwhile, this strong front will bring snow to the Cascades this morning. Snow levels remain around 3000-4500 ft this morning in the Cascades and should fall to around 2500-3000 ft behind the front. Expect the heaviest burst of snow to be this morning between generally 4 AM and 9 AM as the front pushes through. Latest high resolution guidance continues to suggest showers will continue this morning as the upper trough trails behind, with some potential for a convergence zone to develop this afternoon. Current forecast is for generally 4 to 7 inches of snow at the passes, though there is some potential for locally higher amounts if a convergence zone does set up. As such, will hold off on issuance of an advisory with this front, but anyone traveling over the passes should expect to encounter some snow and perhaps reduced visibility in the heavier snow this morning.

Given the lower snow levels and fast moving nature of the front, not much in the way of hydrologic concerns beside some localized ponding of water from the high rainfall rates early this morning. Coastal sites received around half an inch with the main band, with local amounts closer to three-quarters of an inch, the back edge of which is now pushing inland from the coast.

Expect showers to become increasing confined to the Cascades this afternoon (with the exception of a potential convergence zone, as mentioned above) as high pressure starts to build into the region tonight. Heights will rise and the upper ridge will steer the next system well north of the local area. With easing winds, clearing, and plenty of residual low-level moisture from this morning's rain, expect to see fog develop again overnight. A continued drying trend is expected Wednesday, with temperatures remaining close to climatological normals through midweek. Cullen

LONG TERM /THURSDAY THROUGH SUNDAY/. An extended stretch of dry weather appears on tap for the second half of this week under the strong upper level ridge across the region. A front begins to approach the coast Thursday, but ensemble guidance continues to strongly suggest (>80% chance) that this system will split and weaken before it brings any precipitation to the Washington coast. A slightly stronger front may have slightly better luck holding together over the weekend, but again ensembles suggest that anything more than a slight chance of rain for the coast will have to wait until late Sunday or Monday at the earliest. Each of these approaching systems may spread some additional mid/high level clouds over portions of the area. Meanwhile, little change in the temperatures day to day for the second half of the week, with temperatures generally close to normals. Cullen

AVIATION. A frontal system is currently making its way through the area. Ahead of the front the southerly winds have been picking up. All terminals besides KCLM should expect sustained winds 15-20 knots with gusts 25-40 knots. The terminals that will experience the higher winds are KHQM, KPAE, and KBLI. As the front moves through expect rain which could be heavy at times to pass through the area. During the frontal passage expect conditions to go down to MVFR, however if a particularly heavy rain shower passes through IFR is likely for a brief amount of time. The front and its associated precipitation is expected to be completely through the Western Washington area by 1800 UTC today. This will bring improvement in the ceilings, but winds will remain high with post frontal westerlies. There is a chance that a convergence zone will set up with these westerlies. This would result in cloudier conditions and continued rain for KPAE. Overall, winds will be weakening through the afternoon and into the evening as an area of high pressure begins to move into the area.

KSEA . Rain has moved into the area and winds are starting to pick up. Expect winds to continue to increase through the rest of the night with speeds 15-20 knots and gusts near 30 knots possible. The rain will persist through the morning as the front leaves the area. This rain will mostly be light, however their are currently a few areas of heavy rain in the area, based on radar and current observations. The wind shift to westerlies is expected to begin around 1500 UTC, and will remain high until Monday evening.

Butwin

MARINE. The headlines that were previously issued have already started to verify. Gales are currently ongoing for the coastal waters, E and W entrances to the Strait and the Northern Inland Waters. As the front continues to move through Gales are expected to start for the Central Strait. SCA winds are expected to continue for all area waters including the Puget Sound and Admiralty Inlet through this morning. This is a fast moving front so winds are expected to die off quickly.

Following the fronts passage NW swell 15-19 feet is expected for the coastal waters and the W entrance of the Strait. The largest swells are expected to remain in the outer coastal waters. Swell heights will gradually decrease to less than 10 feet by Tuesday afternoon.

HYDROLOGY. No river flooding is expected during the next seven days.
