National Weather Service forecasts and model consensus currently point to a minimum temperature near 57°F in Seattle overnight into August 23, driven by clear skies promoting radiative cooling, light northerly winds, and typical marine-layer moderation under late-summer conditions. This aligns closely with the 58-59°F bin that dominates trader-implied odds, while the secondary 56-57°F outcome captures residual uncertainty in boundary-layer moisture and exact overnight lows. Historical August climatology shows average lows around 57°F, with rare drops below 53°F absent stronger onshore flow or cloud cover. Updated NWS guidance and any late-day model runs will refine these probabilities ahead of final measurement at official stations like Sea-Tac.
