Area Forecast Discussion National Weather Service Seattle WA 856 PM PST Fri Jan 22 2021

UPDATE. Temperatures tonight are trending 5 to 10 degrees cooler than 24 hours ago as northerly wind continues to usher in drier air across the region. Overall, expect overnight lows to dip down into the upper 20s to low 30s across the area. With clear skies and guidance still hinting at a shallow layer of moisture across portions of the southern Sound, could see some areas of freezing fog develop overnight. Will need to keep an eye on this over the next several hours. A few tweaks were made to forecast in the near-term to account for current trends. The previous discussion follows below, with updates made to the aviation and marine sections. 14

SYNOPSIS. Dry and cold conditions expected tonight into Saturday. Wet weather will return to the region Sunday through at least mid next week, with lower snow levels in place. Chances for some lowland snow increase by the middle of next week.

SHORT TERM /TONIGHT THROUGH MONDAY/. A chilly night lies ahead with mostly clear skies apart from some possible freezing fog over parts of the Southwest Interior. Clouds will gradually increase throughout the day on Saturday ahead of an upper trough sliding southward down the British Columbia. Precipitation will spread inland early Sunday morning. For most areas below 1000 feet, it will be in the form of rain. It could, however, briefly begin as snow over portions of Whatcom County where lower dew points and a slow trickle of Fraser outflow could bring the snow level down closer to sea level.

The trough moves onshore Sunday afternoon and evening with snow levels remaining quite low. From Snohomish County southward, there should be enough low level southerly flow to preclude lowland snow accumulation. Whatcom and perhaps Skagit counties could be the exception with perhaps a slushy inch or two of accumulation possible above 500 feet. The upper trough remains centered over the region on Monday with light snow showers remaining possible over the North Interior through the morning hours. Otherwise, Monday will be mostly cloudy with scattered showers and temperatures remaining a bit below normal.

LONG TERM /TUESDAY THROUGH FRIDAY/. Apart from some shower activity over the Olympic Peninsula, much of Tuesday is trending mostly dry. The next in a series of troughs will approach the region by late Tuesday. At this point in time, models are generally favorable with low level thicknesses and temperatures aloft cool enough for possible snow down to near sea level Tuesday night and early Wednesday. As is often the case, the challenge will be with the trajectory of the associated surface low and the amount of moisture available. At least 2/3 of the ensemble members of the GFS/ECMWF produce a fraction of an inch for the Seattle area with 1-3 inches for portions of Snohomish County northward. So, confidence is increasing that there will be a possibility of accumulating lowland snow by midweek. It remains much too early for any significant amount of confidence in amounts.

Nonetheless, the below average temperatures and unsettled conditions will be with us throughout the week ahead. Monitor the forecasts closely as wintry conditions could impact travel next week. 27

AVIATION. Mostly clear skies continuing this evening with light northerly flow. Given the decreasing winds and clear skies, efficient radiational cooling is likely and there may be enough moisture for patchy fog overnight, especially in the typically fog- prone locations. Otherwise, mid-level clouds begin to increase by midday Saturday through the afternoon ahead of the next approaching front. Northerly winds ease overnight, with light winds overnight. Southerly winds increase Saturday ahead of the previously mentioned approaching front.

KSEA . VFR conditions expected tonight with light northerly winds and generally clear skies. May see some patchy fog try to develop west and south of the terminal early Saturday, but remains a low probability (less than 10%) of development at/in vicinity of terminal. Expect a return of lower VFR ceilings to arrive late Saturday afternoon ahead of the next front with MVFR conditions possible by Saturday evening. Light northeast winds likely become southerly after 20z Saturday. Cullen

MARINE. Winds remain below advisory thresholds overnight through Saturday morning. Southerly winds will redevelop over the waters later Saturday ahead of the next front. Expect a return of advisory strength winds Saturday night, with the potential for gales early Sunday morning. Meanwhile, seas will build over the coastal waters, possibly reaching 15 to 20 ft Sunday. Winds and seas ease a bit Monday, but another front may follow for another round of stronger wind and larger seas. Cullen

HYDROLOGY. No river flooding expected over the next 7 days as total QPF is expected to remain light with low snow levels.
