Area Forecast Discussion National Weather Service Seattle WA 825 PM PST Fri Nov 27 2020

UPDATE. The forecast is in good shape this evening with no changes planned.

Evening water vapor imagery depicts weak cyclonic flow extending from the BC Coast southward towards Vancouver Island and N WA, with a notable shortwave trough embedded within near the northern tip of Vancouver Island. Meanwhile, latest WPC surface analysis reveals the reflection of the shortwave over southern BC, with a weak frontal system extending SW from the sfc low center across central Vancouver Island and into the Pacific, just west of the Outer Coastal Water Zones of WA.

Cloud cover this evening has been quick to increase across the local area ahead of the frontal system. MRMS radar imagery shows precipitation associated with the sfc frontal system beginning to move into NW WA. As the aforementioned upper level shortwave trough darts into southern BC overnight tonight, heights will fall across the local area and the sfc frontal system will swiftly pass through. Breezy winds will continue ahead of the front for the next few hours, particularly near the Coast and from the Admiralty vicinity northward through the San Juans and western Whatcom/Skagit Counties. A brief period of rain will also accompany the frontal passage this evening and overnight. Snow level forecast looks good, with Stevens Pass still expected to pick up several inches of new snow thru Saturday morning, with the majority falling after midnight and through daybreak. Hi-res model guidance is picking up on what appears to be a weak convergence zone around Central Puget Sound through Saturday morning (maybe even into the afternoon) which may yield some nuisance spotty light rain and/or drizzle. The remainder of the area will remain dry with weak mid level ridging slowly building into the area.

Previous discussion has been included below with an update to the aviation section.

PREV DISCUSSION. /issued 254 PM PST Fri Nov 27 2020/

SYNOPSIS. Dry weather this afternoon with a system moving through tonight across the area. Rain, mountain snow, as well as breezy weather are expected for some locations. Drier weather Saturday afternoon through Sunday with some ridging building into the area. A stronger system will move through on Monday. Dry Tuesday through much of next week with an upper ridge over the area.

SHORT TERM /TONIGHT THROUGH MONDAY/. Dry weather this afternoon with increasing high clouds as a front approaches the area offshore. Rain will slide onshore this evening and move east across Western Washington through tonight. Breezy southerlies across areas of Whatcom/Skagit/San Juan Islands this evening as the front approaches. Light mountain snow expected tonight into early Saturday morning with snow levels around 3500 to 4500 feet for a few inches at Stevens Pass. Rain to rain/snow mix at Snoqualmie Pass. Some convergence activity may develop early Saturday morning around the central Puget Sound but drier weather for the afternoon as a ridge builds into the area.

Dry weather through most of Sunday with rain sliding onshore late Sunday into Sunday night as a front approaches. The system is expected to track through Sunday night into Monday for rain, mountain snow, and locally windy conditions. It is possible the system tracks a bit further south for less precipitation, which will need to be monitored. Otherwise, the forecast highlights rain Sunday night into Monday with snow for the mountains with snow levels 3000 to 4000 feet. Locally stronger winds for the coast and Whatcom/Skagit/San Juan Islands Sunday night with the front. A few showers around into Monday afternoon as the trough slides east of the area. Temperatures in the 40s to low 50s through early next week.

LONG TERM /TUESDAY THROUGH FRIDAY/. Dry weather Tuesday through next week as an upper ridge builds into the area. Guidance suggests a front approaches the area on Thursday, but most ensembles highlight the front dissipating before it reaches the coast with just slight precipitation chances along the coast on Thursday. Ridging for the area on Friday. Patchy fog may be possible a few of the mornings with the ridge over the area. Temperatures in the 40s to upper 50s through most of the week. JD

AVIATION . A weak front will bring a brief period of rain and sub-VFR ceilings to the terminals tonight and through Saturday morning. This evening, VFR conditions prevail, but radar and satellite imagery show the front beginning to move into the area. Expect clouds to quickly increase and eventually give way to MVFR ceilings (isolated IFR possible) and light rain overnight. Narrow band of rain should clear most terminals early Saturday morning, with some light rain potentially hanging around KPWT, KSEA, and KPAE into the afternoon. Will need to monitor ceiling trends for these sites as recovery may become difficult if light rain lingers. Elsewhere, ceilings should lift back to VFR. Winds S thru Sat afternoon 8-12kts tonight, becoming 5-10kts Saturday and then shifting more E/SE Saturday evening.

KSEA . VFR conditions will give way to increasing clouds and lowering ceilings (MVFR) overnight as a front passes. A narrow band of light rain will accompany the front overnight, with light showers/drizzle likely within a weak convergence zone near the airfield Saturday morning. S wind generally 8-12kts, shifting NE Saturday evening.

Kovacik

MARINE. No changes were needed this evening to the current marine forecast. Recent observations show most of the waters experiencing small craft advisory level winds, so current headlines remain valid. As the front passes across the offshore waters and W Strait this evening, seas will increase and remain between 10 and 13 ft through Saturday afternoon before subsiding in the evening. West winds in the wake of the front down the Strait will keep small craft advisory for the Central and East Strait through 12z Saturday. Previous discussion provided below:

A frontal system will move through the area tonight. Small craft advisory strength southerly winds will accompany the front most waters. There could be an hour or two of low end gale force southerly winds for the northernmost part of the Coastal Waters and the Northern Inland Waters this evening right ahead of the front.

Onshore flow behind the front will quickly ease tonight with weak high pressure moving over the area on Saturday. Winds will turn more east to southeast and start to increase again on Sunday ahead of the next vigorous frontal system.

The aforementioned frontal system will move through the area Sunday night or Monday morning. There is some uncertainty with the exact timing but another round of small craft advisory strength winds are expected and gales are possible for the Coastal Waters, entrances to the Strait, and Northern Inland Waters.

There will be a good push of onshore flow behind the front on Monday - westerly gales are possible in the Strait - then winds will quickly ease as weak high pressure moves over the area again. Offshore flow will develop on Tuesday and continue into Wednesday.
