| Area Forecast Discussion National Weather Service Seattle WA 224pm PDT Monday Jun 8 2026 Synopsis Cool and unsettled conditions will continue across Western Washington through Tuesday. A pattern shift toward dry and considerably warmer conditions is expected late in week as strong high pressure aloft builds into the region. .SHORT TERM /TODAY THROUGH WEDNESDAY NIGHT/...A low pressure system offshore will move into Western Washington tonight. Steadier rain along the Olympic Peninsula will continue to progress eastwards during this period, with the heaviest rain during the overnight period for Puget Sound. This will be a beneficial rain for the region, with Quantitative Precipitation Forecast amounts ranging 1 to 2.5 inches for the Olympics and Cascades, with 0.50 to 1 inch for the majority of the lowlands. Showers will develop after the system moves through on Tuesday, with a convergence zone expected in the vicinity of Snohomish County during the afternoon. Rather marginal instability may result in a few thunderstorms, mainly associated with the CZ Tuesday PM. Otherwise, lingering showers into Tuesday night will taper off into Wednesday morning. In addition to the precipitation, south-southwest winds increase tonight through Tuesday with increasing onshore flow. Widespread wind gusts of 20 to 35 MPH - notably breezy for mid June. Localized gusts to 40 MPH also can't be ruled out, mainly along Whidbey Island due to west winds (REFS probabilities peak around 60-70%), and also in south sound around Tacoma. Winds will subside Tuesday night. Upper level ridging will begin to build into Western Washington on Wednesday. This will result in conditions slowly drying out through the afternoon, widespread morning clouds clearing for some sunshine. Temperatures remain cooler than normal through midweek with highs in the mid 50s to mid 60s. Long Term - Thursday Through Sunday An upper level ridge will continue to build over the NE Pacific Thursday and Friday resulting in dry conditions and a warming trend for Western Washington. The ridge axis will remain over the NE Pacific through Friday with weak troughing over the intermountain West. Temperatures on Thursday will reach the 70s for most locations away from the water, with low 80s for south Sound by Friday. This results in widespread minor HeatRisk by Friday. Ensembles are in general agreement of the upper ridge building further over the NE Pacific Saturday, with the ridge axis shifting towards the Pacific Northwest by Sunday into Monday. Thermal troughing that develops will allow for offshore by late Saturday and continuing into early next week. Temperatures are expected to be the warmest they've been so far this season. Highs by Sunday and Monday will range in the 80s into the mid 90s for some locations. Widespread Moderate HeatRisk is expected Saturday through Monday, with the potential for Major HeatRisk Sunday and Monday as well, particularly away from the water. It will be important to be aware and prepare for hotter temperatures going into the weekend. JD Marine A surface low and associated frontal system will move onshore and weaken into tonight. Elevated southwest winds over the Coastal Waters into this evening will transition more northwest tonight into Tuesday in a post-frontal onshore flow regime. Southwest winds also increase for interior waters Tuesday morning, continuing through the afternoon. Small Craft Advisory wind gusts are expected for most waters on Tuesday due to the strengthening onshore flow. Furthermore, a strong west push through the Strait of Juan de Fuca is expected to result in gale force wind gusts for the central and eastern Strait on Tuesday. A Gale Warning has been issued for this reason. Winds slowly ease Tuesday night into Wednesday. Winds become lighter Wednesday as high pressure builds back into the Coastal Waters. Northwest winds over the Coastal Waters increase Thursday into late week as high pressure continues to build offshore. Flow will transition to offshore at times over the weekend into early next week as a thermal trough expands northwards along the coast. Seas will range between 6 to 9 feet through Tuesday. Brief 10 foot seas are possible along the central and southern outer Coastal Waters as well during this period. Seas subside to 4 to 7 feet by Wednesday and remain in this range into late week. JD Fire Weather The upper ridge building into the area starting Thursday and continuing into early next week will result in hot, dry conditions. Current NBM minimum RH values are running in the 20-35 percent range by next Monday across portions of the area, but lower values are entirely within the realm of possibility. If the cross Cascade gradient goes negative by Sunday, RH values may drop into the teens in the Cascades valleys and portions of the Southwest Interior. This pattern results in elevated fire weather conditions, especially Saturday through at least Monday. JD NOAA Seattle WA Office: Watches - Warnings - Advisories WA...None.
