Area Forecast Discussion National Weather Service Seattle WA 841 AM PST Mon Nov 30 2020

UPDATE /THIS MORNING/. Minor updates made to the forecast this morning to account for current trends. Cold front has reached the Cascades with a strong westerly push occurring down the Strait of Juan de Fuca in its wake. Winds have peaked or will peak in the next few hours so will leave current wind headlines as is. It will still be breezy through the afternoon hours. Steadier rain and mountain snow will turn showery by this afternoon and then gradually taper off. Hi-res guidance suggests a weak convergence zone through the afternoon hours so will need to monitor snowfall rates if it continues across the Cascades. Otherwise rest of forecast is on track and will have full update this afternoon. Updates to aviation and marine sections below. Carpenter

SYNOPSIS. A strong cold front has crossed Western Washington this morning, bringing gusty winds, and heavy lowland rain and mountain snow. Some showers linger into this afternoon, 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 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. Westerly flow aloft will transition northwesterly this afternoon as a trough slides through the area. A front moved through this morning with convective showers across the area as of 16z. VFR/MVFR cigs this morning will scatter for VFR this afternoon. MVFR cigs and rain may linger with any convergence zone development over King/Snohomish Counties, though it is possible the majority of the precipitation is confined to the Cascades. Winds will be breezy west/southwesterly through this afternoon with localized gusts to 30 knots. An upper ridge will move over the area tonight for drier weather. Fog development is expected tonight with clearing skies and light winds.

KSEA . MVFR cigs this morning will scatter to VFR. A few showers may be around into the morning. Convergence zone may slide south over KSEA this evening (01-04z), this may bring brief precipitation and a transition to light north or east winds, though it is expected convergence activity continues to be north of KSEA. Winds will gust southwesterly to 30 knots into this afternoon. Winds will taper off tonight with light winds. Drier weather tonight with fog development possible in the area. JD

MARINE. The front moved through this morning for ongoing gales across most area waters. Winds will diminish through this afternoon with Small Craft Advisory winds across most waters through today. A stronger push through the Strait of Juan de Fuca this morning for gales into the afternoon. Small Craft Advisory issued for the coastal waters and western entrance to the Strait of Juan de Fuca through tonight for increased winds and NW swell of 15-19 feet through this evening. The largest swells will be across the outer coastal waters. Swells will subside below 10 feet by late Tuesday morning. Light winds on Tuesday with offshore flow developing late Tuesday night into Wednesday for the area. JD

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

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
