Official National Weather Service observations at Seattle-Tacoma International Airport (KSEA) confirm the highest temperature on April 29 reached 65°F around 3-5 p.m. local time, with hourly readings peaking at that mark amid mostly cloudy to partly sunny conditions and light winds—driving the market's 100% consensus on the 64-65°F outcome as traders aligned with verified Automated Surface Observing System data. Morning lows near 46°F gave way to gradual warming typical of Pacific Northwest spring patterns, slightly above the April climatological normal of 57°F amid a ridge of high pressure. While data revisions are exceedingly rare post-preliminary release, an audit revealing an overlooked higher reading could theoretically shift resolution, though no such discrepancies have surfaced. Final CLI report expected shortly.
