Synopsis
Drier weather this Thanksgiving afternoon through Friday with some ridging over the area. A front will move quickly through Western Washington Friday night into Saturday. Dry weather Saturday afternoon through Sunday with an upper ridge moving over the area. A stronger system will move through the area Monday with drier weather by Tuesday.

Short Term - Tonight Through Sunday
Dry weather this Thanksgiving evening through tonight with just a slight chance for rain mainly along the northern coast with a system north of the area. Mostly cloudy skies through tonight with patchy fog possible, mainly across the southern tier of the area, with at least some clearing possible. Dry for Friday as ridging over the area slides east with a system approaching.

A front will quickly move through Friday night into Saturday morning for a brief batch of lowland rain and light mountain snow. Snow levels around 3500-4000 feet with the front for a few inches possible at Stevens Pass and a rain to rain/snow mix for Snoqualmie Pass. An upper ridge will build into the area by Saturday afternoon for drier weather and some clearing into the evening. Dry for Sunday as the upper ridge slides east with a front approaching late in the day. Rain may move onshore late Sunday and increase across the area Sunday night. Temperatures through this weekend in the upper 40s to low 50s.

Long Term - Monday Through Thursday
A stronger front will move through on Monday for lowland rain, mountain snow, and breezy weather. Snow levels with this system from 2500 to 3500 feet for moderate snow amounts for the mountains, including the Passes. Guidance has an upper ridge building into Western Washington by Monday night into Tuesday for drier weather through much of next week. Some ensembles highlight the possibility of precipitation, mainly for coastal areas, late Wednesday into Thursday as a front approaches, but some uncertainty whether it dissipates before reaching the area. Temperatures for next week in the 40s to low 50s. JD

Marine
Southerly winds will start to increase across area waters this afternoon and evening as the next system approaches the region. A period of widespread advisory level winds are expected starting this afternoon and evening and will persist through late Friday night as the frontal system sweeps through the area. Some short-lived gales are not out of the question for the offshore waters Friday afternoon, especially in the vicinity of the front. Westerly swells across the offshore waters will increase again on Friday, with seas expected to build to 10 to 15 feet. Seas will then briefly fall below 10 feet again on Sunday, before a new swell train arrives Sunday night into Monday-in conjunction with the next system moving across area waters. Additional headlines will be likely later in the weekend and into next week with another round of elevated winds and seas. Conditions then look to calm Tuesday and look to remain calm through the middle part of next week. Borth

Hydrology
No river flooding is expected through the next 7 days.
