SYNOPSIS
A return to cool and unsettled conditions will continue across the Pacific Northwest this weekend, with little change through early next week. A shift in the pattern is then expected for the second half of next week as high pressure aloft likely develops over the region. This will bring a return of drier and much warmer conditions to the region.

SHORT TERM /TODAY THROUGH MONDAY/
Latest NWS radar imagery reveals the steady precipitation has largely remained draped along and south of a roughly Port Angeles to Mount Rainier line early this morning. With the boundary making little significant progress, still expect the progression of any rain north of Seattle to be rather minimal through the morning today. Some light rain likely expands inland and a little more north, but the focus for the consistent precipitation will remain across the southwestern portions of the local area. In fact areas of Whatcom County near the border will likely remain mostly dry and also a bit on the warmer side. The upper level trough slides east of the region by early Sunday but remains close enough to continue to spread some showers across the local area. More significantly, the next cold upper trough induces stronger onshore flow as it approaches, which will increase the rain coverage across the region. With stronger orographic support, expect heavier rainfall up in the mountains (and snow in the higher Cascades above 4000 ft or so) but some shadowing to keep rainfall totals in the Seattle metro area notably lower. We stay locked in the active pattern with the upper trough crossing the region into Monday. As lapse rates steepen, will have the potential for some isolated thunderstorms and stronger onshore flow will likely bring a developing Puget Sound Convergence Zone.

LONG TERM /TUESDAY THROUGH FRIDAY/
The start of the long term period likely remains unsettled and showery with the lingering upper trough still over the region. Strong support in the ensemble guidance for a pattern shift around midweek though, with high confidence in an upper ridge taking shape over or near the region.
While still some subtle variations among the various clusters of solutions, the general trend suggests this warmer and drier weather will be with us for the second half of the week. Have maintained temperatures in line with the NBM, with likely temperatures in the mid to upper 70s across much of the lowlands late in the week.
