Trader consensus locks in 52-53°F as Seattle's highest temperature on March 17, anchored by official NOAA observations at Seattle-Tacoma International Airport recording a peak of 53°F amid persistent marine layer clouds and cool northerly flows. This fits mid-March climatology, with historical highs averaging 54-56°F but frequently capped lower by Pacific moisture influx, as seen in NWS ensemble forecasts predicting low-50s maxima with minimal upside risk. Pre-event model divergence was narrow, reflecting stable barometric patterns. Realistic challenges—a sudden ridge breakdown enabling downslope warming or clear skies boosting insolation—proved unlikely, cementing the market's near-certain positioning absent data revisions.
