Recent National Weather Service model runs and supporting numerical guidance have converged on a daily high near 58–59 °F at Seattle-Tacoma International Airport, driving the overwhelming market consensus. This positioning aligns with current surface observations showing stable onshore flow, limited cloud cover, and maximum temperatures consistent with late-spring climatology for the Puget Sound region. Key variables such as boundary-layer mixing and sea-breeze timing support the narrow forecast range, with ensemble spreads remaining tight. The primary risk to this outcome would be a late-day shift in wind direction or unexpected marine-layer intrusion that caps temperatures one bin lower, though such adjustments appear unlikely given the latest 00Z and 12Z model cycles.
