Trader consensus on Polymarket assigns a 99% implied probability to a high temperature of 64°F or higher at Seattle-Tacoma International Airport on May 1, driven by the National Weather Service's latest forecast guidance indicating mostly sunny skies and highs near 67-70°F amid a persistent high-pressure ridge over the Pacific Northwest. This positioning aligns with recent model runs from NOAA ensembles, which show low precipitation chances (under 20%) and light north winds of 5-10 mph allowing efficient solar heating on a climatologically mild spring day, where May 1 averages hover around 62°F but current synoptic patterns support above-normal warmth. Realistic challenges include an unforeseen influx of marine stratus clouds overnight or a sudden shift in steering winds introducing cooler air, though forecast confidence remains high with updates expected through early May 1.
