Synopsis
An upper level ridge will rebuild into the region today and Tuesday for warmer and drier conditions. Another upper level trough will produce showers and cooler temperatures across the area Wednesday and Thursday. A weak upper ridge returns late in the week for a drying trend, but continued onshore flow will keep temperatures near normal for the end of June.

Short Term - Today through Wednesday
Forecast remains on track this morning, with no updates required. Expect residual clouds and showers in the lingering PSCZ to fade away through the morning.

An upper trough centered over the interior of British Columbia will continue to weaken today as it gradually shifts eastward into Alberta. This will allow upper ridging to rebuild into Western Washington today. With the resulting subsidence and drier air mass, skies will clear out most areas by this afternoon with high temperatures rebounding to seasonal norms.

Heigheights continue rise into Tuesday as strong upper ridging centered over the Desert Southwest builds into the Northern Rockies. High temperatures across the interior of Western Washington will warm several degrees with 70s common and few spots across the Southwest Interior getting into the lower 80s. A persistent sea breeze will cap temperatures mostly in the 60s along the immediate coast. Upper ridging shifts eastward on Wednesday as yet another upper trough moves into the region. Models continue to generate some respectable Quantitative Precipitation Forecast with this system. Showers will spread onshore across the Olympic Peninsula Wednesday morning then eventually to interior areas by Wednesday evening. There may be enough instability with this system to generate a thunderstorm or two near the crest of the North Cascades Wednesday afternoon. High temperatures will cool 10 or more degrees across the board.

Long Term - Thursday Through Sunday
The upper trough axis shifts onshore on Thursday giving nearly all of Western Washington a shot at some measurable precipitation. Meso models are keying in on a decent convergence zone setting up early Thursday morning. The trough axis is expected to shift east of the Cascades by Thursday afternoon. The return of some weak upper ridging is expected to lead to a drying trend and somewhat warmer temperatures heading into the end of the week. For Sunday and beyond, ensembles generally agree that weak upper troughing just offshore will ensure that onshore flow continues keeping temperatures from getting much above seasonal normals as June comes to a close. 27

Marine
Quick update to seas this morning as latest buoy observations shows seas persisting at 6-9 ft over the coastal waters. Expect seas to gradually subside back towards 4-6 ft tonight into Tuesday and hover within this range for the next several days.

High pressure over the NE Pacific will maintain relatively calm conditions and onshore flow through Tuesday. A weak frontal systems will push inland on Wednesday and again over the weekend. Strongest winds will be through the Strait of Juan de Fuca through the period with possible Small Craft Advisories at times throughout the week. 33/14
