Area Forecast Discussion National Weather Service Seattle WA 316am PDT Sat April 26 2025 Synopsis High pressure remains in place through the weekend, with some cooling on Sunday. A weak frontal system will move into the area early in the week for light precipitation, with ridging rebounding in the second half of the week. Short Term - Today through Monday Some stratus has made it to the southern coast early this morning, primarily impacting Grays Harbor County. It is unlikely that much more stratus will get any further east than Olympia throughout the rest of the morning. Isolated pockets of lower clouds are possible in portions of Puget Sound but will not be widespread if they develop. Onshore flow will get a bit breezy at times by early this afternoon, primarily in the southwest interior, along the coast and through the Strait of Juan de Fuca. Gusts of 25 to 30 mph are possible through the Strait and along the coast. Temperatures today will still be in the mid to upper 60s across Puget Sound and low to mid 50s along the coast. A weak low traversing to the south by Sunday will cool things off a bit into the low 60s and upper 50s and keep Washington under split flow aloft. A more zonal flow pattern sets up on Monday and opens the door for the next weak system to arrive Monday night into Tuesday. Quantitative Precipitation Forecast amounts are generally light, under a quarter of an inch with the exception of the coast and north Cascades seeing slightly above a quarter inch. This system has high snow levels, keeping rain in the forecast for all Cascade passes. Long Term - Tuesday Through Friday Rain is expected to taper off by late Tuesday morning, with lingering showers in the Cascades. A ridge returns by Wednesday, bringing back warmer temperatures through Thursday where highs could reach the mid 70s. Chances for rain return late next week, but some timing discrepancies between the models right now limit what to expect in terms of rainfall amounts. 21 Marine Onshore flow pattern will continue through the weekend. High pressure will build over the waters later Sunday, with a weak weather system moving across the waters later Monday into Tuesday. High pressure will rebuild Wednesday.
