Recent National Weather Service guidance and ensemble models indicate Seattle will remain under a thermal ridge favoring subsidence warming, with light onshore flow from the Pacific and Puget Sound moderation expected to cap the daily maximum near 82–85°F on June 24. This positioning keeps the 84–85°F and 82–83°F bins closely matched, as small shifts in cloud cover, sea-breeze timing, or model bias in boundary-layer mixing can easily swing the peak by 1–2°F. Historical June climatology shows rare exceedances above 88°F without stronger offshore flow, while marine influences reduce downside risk below 80°F. Updated high-resolution runs and afternoon observations will be the key near-term catalysts.
