Synopsis for the northern and central washington coastal and inland waters - Broad surface ridging will remain centered well offshore with low pressure inland throughout the week ahead for varying degrees of onshore flow.

Area Forecast Discussion National Weather Service Seattle WA 808 AM PDT Tue May 14 2024

SYNOPSIS
A ridge of high pressure will provide dry and warmer conditions for the region through Wednesday. An upper trough dipping southward from British Columbia will produce clouds and cooler temperatures Thursday through Saturday along with a chance for showers across mainly northern portions of the area. Below normal temperatures and somewhat unsettled conditions could persist into the early part of next week.

UPDATE
Quiet conditions this morning with mostly clear skies across the region. Highs today will reach the upper 60s to low 70s. The current forecast is on track and no updates are planned.

SHORT TERM /TODAY THROUGH THURSDAY/
An upper ridge centered well to our southwest will build into the area today and Wednesday.
This will allow for dry conditions and a modest warming trend. Low level onshore flow will keep temperatures in check with 60s for coastal areas and mid 60s to mid 70s for the interior lowlands. The upper ridge will flatten on Thursday in response to an upper level trough moving onshore over British Columbia. This will act to increase the onshore flow and the end result will be increasing cloud cover and cooler temperatures. Onshore flow becomes relatively strong Thursday afternoon into Thursday night and this will likely initiate a convergence zone over Skagit/Snohomish counties.

LONG TERM /FRIDAY THROUGH MONDAY/
An upper trough axis will be over Western Washington on Friday for another mostly cloudy and cool day. The best chance for showers will be over the mountains and across northern portions of the lowlands. Snow levels will dip to around 5000 feet...something to consider if you've got hiking plans in the higher backcountry late this week. For the weekend and beyond, uncertainty is the word for the day to day forecast. Cluster plots show a considerable spread in solutions. Ensemble height anomalies show ridging retrograding well offshore with a mean upper trough position over the Northern Rockies heading into early next week. While not a particularly wet scenario, this does suggest that temperatures will be a little below average and shower chances will linger...especially over the higher terrain.

AVIATION
Upper level ridging in the eastern Pacific will keep northwesterly flow aloft over W WA at least into Wednesday. Surface flow this early morning generally light and variable with a few exceptions reporting northerly winds 5-10 kts. Majority of TAF sites should see similar low level winds develop by this afternoon.

Morning MVFR CIGs remain confined along the coast (and far into the Cascades as well as south of Chehalis). Any lower CIGs are unlikely to materialize this morning further inland due to there being stronger flow aloft from the jetstream passing in northern WA.
Majority of terminals will see VFR today (exceptions along the coast with weak onshore flow).

KSEA...VFR conditions expected to persist throughout the TAF period, with only high clouds. Northerly winds 6-10 kts will persist through about 15Z before turning light and variable. Northerly winds 5-10 kts return by 20Z and persist into early Wednesday morning.

18/HPR

MARINE
High pressure will build off the coast throughout this week. North to northwesterly surface winds starting out over the Pacific waters then pushing inland will give rise to SCA concerns throughout the day. Headlines are staggered from west to east and limited to the coastal waters and Strait at this time, although consideration for Strait-adjacent waters may be needed depending on future model solutions. Another push down the Strait is possible for Wednesday into Thursday while the coast may see speeds ramp up for late Thursday and all of Friday.

Seas will hold around 4 to 6 ft through Friday before increasing 8 to 12 ft from Friday into the weekend.
