Synopsis for the northern and central washington coastal and inland waters - Gusty offshore winds expected today ahead of an approaching frontal system. Seas will rise as the low pressure system moves inland, contributing to steeper waves. Additional marine headlines are expected over the weekend as a westerly surge moves through the strait of juan de fuca.

Area Forecast Discussion National Weather Service Seattle WA 818 PM PDT Fri Apr 19 2024

UPDATE
Clear skies continue this evening with upper ridging across the area. Offshore winds continue to be locally breezy in the Cascade Gaps where wind gusts of 20 to 30 MPH are likely into Saturday. Otherwise, high clouds will slowly increase into Saturday ahead of the next front.

SYNOPSIS
Ridging will maintain dry and warm conditions into Saturday ahead of an approaching front that will bring in light lowland rain, mountain snow, and breezy winds. Unsettled conditions will continue through the remainder of the weekend.
Next week will start out drier and warmer ahead of more rainy weather mid- week.

SHORT TERM /TONIGHT THROUGH TUESDAY/
Dry conditions will prevail today as a shortwave ridge continues to shift inland. Temperatures across the lowlands are on track to peak near or slightly below the 70 degree mark as offshore continues. Areas sheltered from the easterly winds will once again see much cooler overnight lows in the 30s, whereas more open areas will bottom out in the low to mid 40s. Temperatures will continue a warming trend into Saturday as surface winds shift southerly in the warm sector ahead of an incoming front, with ensembles showing a moderate (50% to 60%)
chance of surpassing 70 degrees across much of the lowlands.

A front will cross western Washington mid-day Saturday, bringing in a band of precipitation and breezy southwest winds as the front moves through. Post-frontal conditions will destabilize with troughing maintaining shower activity through Sunday afternoon.
Snow levels will lower to around 2500-3000 ft by Sunday morning with generally light rainfall amounts for the lowlands and 1 to 2 inches of snow accumulation through the Cascade passes over the span of the weekend. The bulk of the moisture with this system will be focused over the Northern Cascades, where the higher peaks will see up to 6 to 8 inches of snow through Sunday. Some mesoscale models also hint at convergence activity from Skagit County northward, which would locally enhance snowfall amounts over higher terrain, but confidence is low. Lingering shower activity will be cut off later on Sunday as a positively tilted trough swings a front across the Pacific Northwest. Cool air aloft paired with onshore flow will make for a brisk day on Sunday, with temperatures in the lowlands peaking in the mid 50s.

Decreasing cloud cover overnight Sunday into Monday morning paired with light winds will allow temperatures to drop quickly.
Conditions will be conducive for areas of frost to develop outside of the Puget Sound metro areas. High pressure will build inland on Monday, allowing conditions to dry out and temperatures to rebound back into the 60s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Temperatures will warm into Tuesday as high pressure continues to amplify into western Washington. Models continue to show large model differences mid- week and beyond, but ensembles maintain a return to near normal conditions with a chance of light precipitation through the remainder of the period.

AVIATION
Upper ridge axis will shift onshore overnight then east of the Cascades on Saturday morning as a front approaches the region. West to northwest flow aloft will become southwesterly after 18Z Saturday. High level moisture will gradually increase overnight with ceilings lowering to MVFR along the immediate coast by Saturday afternoon as precipitation spreads onshore. Low level easterly flow will quickly flip onshore with the arrival of front. Gusty post- frontal W/SW surface winds are expected across much of the area Saturday afternoon and evening.

KSEA...Increasing high and mid level clouds late tonight into Saturday morning. Areas of light precip are expected to reach the terminal after 00Z, but ceilings likely remaining above MVFR thresholds. E/NE surface winds will reverse to S/SW around 20Z on Saturday and remain gusty well into Saturday evening. 27

MARINE
Broad high pressure situated across the Pacific Northwest, with a weak thermal trough situated along the coastline. The next frontal system is situated well offshore, sitting around 135 W as of this afternoon. Winds are offshore/easterly across the coastal waters today, with the breeziest winds through the Central Strait of Juan de Fuca, reaching 15 to 20 kt. Winds should remain just below Small Craft Advisory level going into tonight, so the advisory has been dropped. Offshore flow will be enhanced through the gaps around the Olympics tomorrow as the system approaches, thus a Small Craft Advisory will begin early tomorrow morning for the coastal waters north of Point Grenville, as well as the Central and West Entrance to the Strait of Juan de Fuca. Winds will pickup in the coastal waters north of Cape Shoalwater, as well as into the Eastern Strait of Juan de Fuca and through Puget Sound Saturday afternoon as the front moves through the coastal waters. Winds look to ease area-wide late Saturday night into Sunday.

High pressure will return Sunday afternoon into the beginning of next week, with a few pushes of westerly winds down the Strait of Juan de Fuca which will likely require additional headlines.

Seas remain around 3 to 5 ft through tonight. Seas will rise to 8 to 12 ft Saturday afternoon into Sunday. Seas may be steep, particularly through the outermost waters, over the weekend with the dominant period being 9 seconds. Seas decreasing to 6 to 8 ft Sunday and Monday then decreasing further into midweek.
