Synopsis
A frontal system will continue to move through Western Washington tonight with lowland rain, breezy winds, and mountain snowfall. Post frontal unsettled conditions will continue on Wednesday. Drier, cool weather Thursday and Friday before a system will approach the area offshore over the weekend.

Short Term - Tonight Through Thursday Night
Both latest satellite and radar clearly show the back edge of the current front passing over the Olympic Peninsula, with the northwest corner of the landmass already entering into the post frontal environment. This still means the majority of W WA is in for a wet evening and at least some part of the tonight period...with the Cascades checking out last as activity there is slated to go into early Wednesday morning. Winds have eased, allowing for inherited Wind Advisories to expire. Breezy conditions and occasional gusts will still be a thing into tonight...and so some isolated wind-related impacts will still be possible...but the threat for widespread strong and gusty winds has largely wrapped up.

All according to plan, or so it seems, as inherited forecast handles this well. Thus, no need for any evening updates. For additional forecast details, please refer to the Previous Discussion section below.

From Previous Discussion...A frontal system continues to move across western Washington this afternoon. Steady rain through this evening with a brief convergence zone progressing across central Puget Sound tonight. South winds will remain breezy, peaking this afternoon and evening. A Wind Advisory remains in effect for the Grays Harbor County coast, as well as Admiralty Inlet and Everett region, with gusts of 35 to 45 MPH in these areas. Winds remain breezy elsewhere, with gusts ranging 25 to 40 MPH. Increasing foliage will make trees more susceptible to damage, which may result in localized power outages.

Snow levels around 4000 feet this afternoon will fall to 1500 feet by Wednesday morning, resulting in snow for the Cascades and Olympics, including the Passes. Snow will continue at times for the Cascades through Wednesday. Total snowfall amounts of 8 to 14 inches are expected for Snoqualmie and Stevens Passes, with locally higher amounts near 18" around White Pass and Mount Baker. A Winter Storm Warning remains in effect. Snow will subside Wednesday night.

An upper low will move across the Pacific Northwest on Wednesday. This will result in colder temperatures aloft, and increasing instability. Scattered showers will be around Wednesday, with the threat for isolated thunderstorms. The probabilities for thunderstorms peak between 15 to 25 percent, primarily during the afternoon. Lightning, breezy winds, as well as small hail may accompany any heavier showers.

Drier conditions will develop Wednesday night as conditions begin to clear for some areas. Temperatures by Thursday morning will fall into the low to mid 30s, resulting in potential frost concerns. Will also need to monitor freeze conditions for portions of south Sound. Otherwise, increasing sunshine is expected during the afternoon Thursday.

Long Term - Friday Through Tuesday
Weak upper ridging brings drier conditions on Friday. Will need to monitor the frost potential once again, mainly from Olympia southwards Friday AM. An upper low will track towards the west coast over the weekend. Uncertainty remains in ensembles in the location of the upper low by Sunday, which impacts the eastward extent of precipitation over the weekend. At this time, the highest probability for rain over the weekend is along the Olympic Peninsula, but precipitation chances extend through Puget Sound, especially by Sunday. The bulk of the energy then moves towards California by early next week, which may result in drier conditions for western Washington. However, slight chance of precipitation remains in the forecast at this time. A warming trend exists over the weekend with highs reaching the low to mid 60s. JD

Marine
Stronger south winds continue through this evening as a weather system moves across the waters. Gale force wind gusts are expected at times for the Coastal Waters, as well as Puget Sound and Admiralty Inlet through this evening. SCA (Small Craft Advisory) winds are expected for other waters into the evening. Onshore flow increases this evening into tonight with a strong westerly push through the Strait of Juan de Fuca. Gale Warnings have been issued for the central and eastern portions of the Strait of Juan de Fuca this evening into tonight, with gale force west wind gusts expected. Winds will slowly subside late tonight into Wednesday for the majority of waters. Northwest winds increase for the outer Coastal Waters late Wednesday before subsiding through Friday. Another weather system will approach the waters offshore over the weekend, resulting in increased southerly winds for the Coastal Waters.

Seas will build to 9 to 12 feet this evening. Seas will remain around 8 to 10 feet Wednesday before building to 10 to 13 feet Wednesday night. Seas will subside Thursday through Friday. JD

Hydrology
No river flooding the next 7 days.
