Area Forecast Discussion National Weather Service Seattle WA 850 PM PDT Mon Apr 22 2024

UPDATE
High clouds are moving across the area this evening, with continued northerly winds for most areas. Dry conditions will continue through Tuesday with an upper ridge, with temperatures tonight in the upper 30s to mid 40s.

SYNOPSIS
High pressure will maintain mild and dry conditions across the region through Tuesday. From Wednesday through the end of the week, expect a series of disturbances to bring a return of clouds and precipitation with temperatures trending closer to seasonal normals. This pattern will remain through the start of next week with periodic round of mountain snow and lowland rain.

SHORT TERM /TONIGHT THROUGH FRIDAY/
Mostly sunny conditions across the region this morning with temperatures climbing through the 50s and a few spots into the lower 60s already this afternoon.
Surface high pressure will shift eastward into Tuesday as a thermal trough builds northward near the coast. This will induce light offshore flow across the region by the afternoon. This will likely bring relative humidity values down toward the 20-30% range for a few hours in the afternoon. Fortunately onshore flow looks to return late in the day which should boost humidities overnight, but any fine fuels may be receptive to sources of ignition. Expect temperatures to top out around 70 through the interior.

Increasing cloud cover and onshore flow returns on Wednesday as a weak disturbance pushes through. Not much moisture with this one, but light showers are possible in the higher terrain of the Olympics and Cascades. Otherwise, temperatures trending back closer to, or slightly below, seasonal normals. Not much change either into Thursday with another frontal system following. Cullen

LONG TERM /SATURDAY THROUGH TUESDAY/
While still much uncertainly in the way of more subtle differences in the pattern through the extended, overall expect a cool and showery springtime pattern to continue for the weekend and start of next week. With a trough likely setting up offshore, expect several rounds of precipitation as the individual impulses rotate across Western Washington. Snow levels Friday through the weekend generally hold around 4500 feet or higher, so most of the snow will be confined to the higher mountain elevations but can't rule out a light snowfall down to pass levels at times. The highest rainfall amounts look to remain over the Olympics and will have to monitor for any rises, but amounts remain well below hydrologically impactful rains for most of the area - of course, the more flood-prone Skokomish River may be one to nonetheless need to monitor. All that to say, a rather common springtime pattern of cool and cloudy conditions with temperatures generally near or slightly below normal for the long term period. Cullen

AVIATION
Westerly winds aloft as a weak upper level ridge moves through the area. VFR conditions are expected to continue through the TAF period with mostly clear skies, some high clouds moving through this evening.

Northerly winds with occasional gusts to 20 kt this afternoon, easing to light and variable tonight. Winds will be slow to get going tomorrow, light southeasterly/easterly 4 to 8 kt.

KSEA...VFR through the TAF period with high clouds tonight.
Northerly winds 8 to 12 kt with gusts up to 20 kt will ease to light northerly/variable before becoming southeasterly 4 to 8 kt after around 18Z tomorrow.

LH

MARINE
Broad surface high pressure will gradually weaken as a thermal trough builds along the Oregon coast and a frontal system moves southward from the Gulf of Alaska. This system will make its way to western Washington Tuesday night into early Wednesday, but will largely fall apart by the time it arrives. The next, more substantial, low pressure system will move through the region on Thursday. Winds will likely pick up on Thursday with this system but the exact details are uncertain with evolution and track of this system.

A push of westerlies are expected into the Central and East Entrance to the Strait of Juan de Fuca beginning Tuesday afternoon, for which a Small Craft Advisory has been issued. Winds will ease below advisory criteria into Wednesday but will remain breezy through Wednesday evening.

Seas are expected to remain around 4 to 6 ft through the rest of this week.

HYDROLOGY
No river flooding is expected through the next seven days.
