Trader consensus on Polymarket centers on a Seattle high of 52-53°F at 50% implied probability, driven by the National Weather Service's latest forecast guidance showing a daytime maximum near 52°F on March 26 under partly cloudy skies and persistent light onshore flow from the Pacific. Ensemble models from NOAA's Global Forecast System and European Centre for Medium-Range Weather Forecasts have converged on this range following the 12Z update, reflecting a stable upper-level ridge and marine layer suppressing warmer temperatures typical for late March (historical average high ~55°F). Recent soundings confirm cool boundary layer air, limiting diurnal heating, though uncertainty persists around afternoon cloud breaks that could nudge readings toward 54-55°F (24.5%). Next model runs expected within 24 hours may refine these odds ahead of the event.
