Area Forecast Discussion National Weather Service Seattle WA 1025 AM PST Fri Jan 28 2022

SYNOPSIS. Upper level ridge over the area will shift southeast and weaken on Saturday. A front will move through the area Saturday night and Sunday for a return of rain and mountain snow. Wet weather will continue through early next week. High pressure may bring another break in the weather toward the latter half of the week.

SHORT TERM /TODAY THROUGH SUNDAY/. Fog not as widespread this morning as it has been for much of this week . although still some diminished visibilities still out there. Will see conditions continue to improve as the day progresses although not as much clear sky as yesterday expected given current satellite shows some high clouds over the area. Still, as these are only high clouds, the old phrasing of 'fair' is certainly applicable today with plenty of peeks of sun likely.

Forecast remains generally unchanged as models remain consistent on keeping the ridge in place through Saturday, although gradually flattening out, and bringing the next frontal system into the area Saturday night. This will make for a wet remainder of the weekend as the front slowly moves through the area much of the day Sunday. Precip with this system is not expected to be anything special, with lowland rain and mountain snow expected. Snowfall amounts in the mountains still does not look to meet any headline criteria at this time.

Temps today and Saturday will continue to warm with highs in the mid to upper 40s and upper 40s to lower 50s accordingly. Frontal passage and precip on Sunday will bring temperatures back down . but not too much . with highs in the mid to upper 40s.

Last thing to mention is air quality. With the upcoming change in the weather pattern, increased mixing is still expected as the front approaches. However, with the ridge still fixed overhead in the very near term /today into Saturday/, in collaboration with Air Quality partners have seen it fit to extend current Air Stagnation Advisory until noon Saturday.

Otherwise, inherited forecast is on track and no need for additional morning updates. 18

LONG TERM /MONDAY THROUGH THURSDAY/. From Previous Discussion . We'll remain under moist N/NW flow into early next week for additional rain and mountain snow showers. High pressure (centered offshore) may shift inland again mid/late week for another break in the weather. 33

AVIATION. Upper ridge shifts eastward through the day, with only a few pockets of shallow fog remaining. Outside of these areas, VFR conditions today with only variable thin mid/high clouds at times. Low level offshore flow continues near the surface and will generally stay light at all terminals.

KSEA . Some patches of fog at and near the terminal area this morning, but these should continue to decrease and scatter out through the remainder of the morning. Otherwise, light surface winds and variable mid/high clouds at time will be the only factor with VFR conditions prevailing. Could see a shallow low stratus layer again late tonight after 12z toward daybreak, but confidence remains only moderate in this occuring. Cullen

MARINE. Fog continues to scatter out of the interior waters this morning. Meanwhile, no wind or sea related marine concerns with light winds over the waters today and into at least early tomorrow as the high pressure gradually shifts away from the area. Winds will become southerly today and especially Saturday with the ridge the next front approaching, but are likely to remain below advisory criteria until the post-frontal westerlies arrive on Sunday. Seas will build behind the front, approaching 10 to 12 feet early next week. Cullen

HYDROLOGY. No river flooding expected in the next 7 days.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Air Stagnation Advisory until noon PST Saturday for Admiralty Inlet Area-Bellevue and Vicinity-Bremerton and Vicinity- Cascades of Pierce and Lewis Counties-Cascades of Snohomish and King Counties-Cascades of Whatcom and Skagit Counties- East Puget Sound Lowlands-Eastern Strait of Juan de Fuca- Everett and Vicinity-Hood Canal Area-Lower Chehalis Valley Area-Olympics-San Juan County-Seattle and Vicinity- Southwest Interior-Tacoma Area-Western Skagit County- Western Strait of Juan De Fuca-Western Whatcom County.
