Synopsis for the northern and central washington coastal and inland waters..Gusty winds due to a cold front will persist into Thursday evening before winds taper overnight.

Fog development overnight later in the week could lead to reductions in visibilities over area waters.

Area Forecast Discussion National Weather Service Seattle WA 952 AM PST Thu Jan 20 2022

SYNOPSIS. An exiting weather system will allow for some lingering showers into the afternoon before conditions start to dry up. Upper level ridging will take over from there and is expected to give Western Washington an extended period of dry but foggy weather.

SHORT TERM /TODAY THROUGH SATURDAY/. Current radar shows rain associated with the exiting cold front over the Cascades while satellite imagery shows the front actually east of the crest. The other point of interest on current radar is the development of a convergence zone over portions of Whatcom and Skagit counties. Model data suggests that a little nub of a shortwave may allow for this CZ to sag further south later on today and this evening which may allow for two concerns. First will be hydrologic effects for King County rivers where a Flood Watch is now in effect, but for more details on that, please refer to the HYDROLOGY section below. The second may be snow impacts for the passes, particularly Stevens. At this time, QPF values remain below advisory thresholds however this will be something to monitor throughout the day and a short-fused advisory there might not be out of the question.

Upper level ridging starts to assert itself over W WA as early as tonight allowing for drier conditions. Friday and Saturday look to remain dry as said ridge remains the dominant weather feature over the area. However, with stable conditions and lingering surface moisture, fog will likely be an issue in the lowlands.

Thanks to the cold front passage, most locations should have already seen their high temp for today /generally in the lower 50s/ and will see temps gradually diminish throughout the day . although afternoon temps will linger in the mid to upper 40s. Highs Friday and Saturday are nigh identical . with temps in the mid to upper 40s.

Inherited forecast holding together well. No immediate need for a morning update at the time of this writing. 18

LONG TERM /SUNDAY THROUGH WEDNESDAY/. From Previous Discussion . Dry stable conditions will continue through the long term. With these prolonged conditions, there is some concern regarding air stagnation. Due to minimal mixing, we will likely see air quality decrease, especially for valleys that frequently experience temperature inversions, as well as large population centers.

Temperatures will be on the warm side for Western Washington in January. Highs are to be in the mid 40s to low 50s for the lowlands. Lows will also be "toasty" and in the mid 30s to mid 40s during the week.

Butwin

AVIATION. Winds will shift becoming more westerly toward today behind the cold front. Ceilings are expected to slowly improve as rain tapers. However, a Puget Sound Convergence Zone will likely develop near/around KPAE this afternoon then shift towards KSEA this evening before dissipating. Winds will taper off between 06-12z with generally light winds favoring a northerly direction during the bulk of the day Friday.

KSEA . Gusty west to southwest winds behind the cold front today into this evening. Ceilings are expected to slowly improve during the day. A PSCZ is expected to develop near KPAE today, then gradually shift south this evening. Recent trends indicate a brief period of SHRA this evening at KSEA as the convergence zone weakens between 02-07z. Low CIGs/Fog may develop again as winds become very light early Friday morning.

Wolcott

MARINE. Expect continued advisory strength winds across the waters, with a stronger onshore push through the Strait continuing advisory conditions through the evening. Expect seas to build over the coastal waters initially with the winds today, but more significantly Friday will an arriving west swell behind the weather system. Seas then subside but build again early next week with another west swell arriving. Meanwhile, stronger high pressure will build over the waters later this week and into the start of next week, with generally light winds across area waters.

HYDROLOGY. The weather system moving through the area today has brought 2 to 3 inches of rain in the area of the US 2 corridor, with lesser amounts elsewhere in the mountains. this is causing sharp rises on the Tolt and Snoqualmie Rivers, and threatening to exceed flood stage. The snow level is around 8000 feet but will be coming down later today as cooler air filters in behind the cold front. A convergence zone is expected to form in the south Snohomish to north King County area - yes, along the US 2 corridor. There is, as usual, a fair amount of uncertainty as to the exact location of the precipitation, the amount of precipitation, and how much will fall as snow in that area. An additional point of uncertainty is how much water will spill from the Tolt Dam. A flood watch is out for King County and the river forecasts have been updated showing crests above minor flood for the Tolt and below minor flood for the Snoqualmie near Carnation. We expect those river forecasts to be adjusted throughout the day and evening. JBB
