Recent forecasts from the National Weather Service and major models show Seattle transitioning from a brief warm spell with highs near 85–86°F to cooler onshore marine flow on June 25, favoring daytime peaks in the upper 60s to low 70s under increasing clouds. This setup, driven by strengthened westerly winds and a marine layer that promotes stratus development, limits solar heating and aligns with climatological June averages near 72°F. The near-even market split between 68–69°F and 70–71°F reflects uncertainty in exact cloud timing, marine intrusion depth, and any late-day clearing that could add a degree or two at Sea-Tac. Updated model runs and NWS briefings through tomorrow morning remain the key catalysts for shifts in trader positioning.
