Area Forecast Discussion National Weather Service Seattle WA 242 PM PST Fri Jan 22 2021

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/. Skies clearing nicely across the region this afternoon as dry northerly flow scours out any remaining moisture. 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. Clear skies will continue through tonight and into Saturday morning. By the afternoon clouds are expected to start moving into the Western Washington area ahead of a front. Aside from coastal locations such as KHQM, VFR conditions will remain in place until the evening hours. Now all of that was in regards to clouds aloft, not for the potential for fog. We are anticipating some patchy areas of fog to from, particularly for south of the Puget Sound and in including terminals such as KPWT and KOLM here we will likely see IFR conditions, with some intermittent LIFR. As a result of temperatures being at or below freezing this fog will likely create for some icy surfaces. Any fog that formed should mix out by early afternoon.

Wind wise, the northerly winds are expected to ease overnight and remain mostly light throughout the day on Saturday. The change over to more southerly winds ahead of the front will gradually happen through the afternoon and by Saturday night all terminals will be in that dominate southerly flow. Late Saturday night the winds will begin to pick up to 7-10 knots, with the potential for some gusts closer to 15 knots at KHQM, KBLI and KPAE.

KSEA . Clear skies will continue through the rest of today and into Saturday. The potential for some patchy fog near by the terminal is there, but with northerly winds, fog should stay out of the KSEA. Clouds will begin to move into the area Saturday afternoon, but things should stay in VFR until Saturday night. North winds will be weakening through the night, and will gradually shift southerly tomorrow afternoon.

Butwin

MARINE. Generally things are fairly tranquil over the area waters this afternoon. We expect the northerly flow to be easing through the rest of today. Saturday afternoon winds will begin to shift to more southerly ahead of an approaching front.

Winds from this approaching front will begin to pick up to small craft advisory level late Saturday night/early Sunday morning. As per usual in these parts winds will pick up over the coastal waters first and a few hours later the inland waters. Once the front passes through we are expecting a set of northwest gales to occur over the coastal waters as well as the West Entrance to the Strait of Juan de Fuca. Winds will begin to ease Sunday night into Monday.

Swells are expected to remain under 10 feet ahead of the front but once it passes through expect swells to increase. In the near coastal waters expect swells to be close to 15 feet through Monday morning. The outer coastal waters are expected to have swells 15-20 feet through this same time frame.

Butwin

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