Current National Weather Service and ensemble model guidance points to a Seattle high near 72°F on July 4, with morning marine-layer clouds giving way to afternoon sun under moderate onshore flow. This keeps the most likely range at 70–73°F, matching the tightly bunched market leaders. Key differentiators among these bins include subtle variations in boundary-layer mixing depth and the timing of any stratus burn-off, which can add or subtract a degree or two. Historical July climatology centers near 75°F, but persistent Pacific high pressure and a lack of offshore warming have held recent daily maxima a few degrees cooler, anchoring trader probabilities in the low-to-mid 70s rather than the upper 70s or low 80s. Updated short-range model runs tomorrow morning will provide the final calibration before resolution.
