Northern and Central Washington Coastal and Inland Waters - PZZ100
High pressure offshore with thermal low pressure east of the Cascades will result in varying degrees of onshore flow for much of the upcoming week.

High pressure aloft and low level onshore flow will maintain a dry pattern across the region this week. The upper ridge will build closer to the Pacific Northwest around midweek, allowing for notably warmer conditions during the second half of the week.
.SHORT TERM /TODAY THROUGH THURSDAY/...Areas of low clouds will burn off by midday for a mostly sunny afternoon under continued low level onshore flow. Highs will be slightly above normal. An upper ridge over the Intermountain West will build slightly westward Wednesday and Thursday. This will turn the flow aloft for Western Washington more southerly and weaken low level onshore flow slightly. The result will be less morning low clouds and a gradual warming trend. Highs will be well into the 80s for the interior by Thursday with a few lower 90s possible. The southerly flow aloft could also bring some elevated smoke later in the week but most of this is expected to stay to the east and degraded air quality is not expected for now. Schneider
Long Term - Friday Through Monday
Previous discussion...Warm and dry remains the story for next weekend. A few more warm days in store Friday and likely Saturday as the upper ridge axis continues to shift a bit westward. The good news for us locally is that most ensemble guidance focuses this upper ridge axis somewhere near the Idaho panhandle or western Montana into the weekend. While the air mass will warm considerably, the ridge looks to remain far enough east to maintain onshore low-level flow through across western Washington. This will lead to overnight temperatures cooling into the upper 50s to near 60, which should mitigate some of the potential impacts from heat. Some of the communities on the eastern side of the metro area and eastward into the Cascades may be the warmest spots, especially getting into the Cascade valleys where a strengthening subsidence inversion may maintain some warmer nights.
It is worth noting that a few ensemble solutions suggest the potential for some convection to bring showers near the Cascade crest and potentially further westward at some point over the weekend late Saturday or into Sunday, but overall parameters look marginal at best to support much over the local area with somewhat better support to our south and east. As a result, given this, coupled with the very relatively low probability suggested by the majority of guidance, have instead elected to maintain a dry forecast for now. Ensembles do suggest a shift back to stronger onshore flow and a return of slightly cooler temperatures (closer to seasonal normals) by the end of the weekend or the start of next week as the next low off the B.C. coast begins to strengthen and move a bit closer to the region.
