Trader consensus on Polymarket favors a high temperature of 52-53°F (45%) in Seattle on March 26, aligning closely with the National Weather Service's latest forecast of a high near 53°F under sunny skies. This positioning stems from overnight model runs of the GFS and ECMWF, which converged on mid-50s peaks after a cool frontal passage late last week advected crisp Pacific Northwest air, tempering earlier warmer projections. Seattle's March climatology averages highs around 55°F, but current upper-air patterns suppress significant warming. Key uncertainties include minor diurnal fluctuations and potential thin high clouds; official observations from Sea-Tac Airport later today will resolve the market per NOAA measurement standards.
