**Trader sentiment for Seattle’s July 2 high temperature centers on a narrow cluster of mid-60s outcomes (64–69°F capturing roughly 63% of probability), reflecting consensus around a cool, marine-influenced day following the mid-June heat wave.** Official National Weather Service guidance and model consensus point to highs near 67°F under increasing onshore flow, with possible morning clouds, isolated showers, and a broad upper-level trough keeping the region below seasonal norms (historical early-July average ~74–75°F). This setup favors the leading 66–67°F bin while leaving room for modest upside to 68–69°F if afternoon sun breaks through more than expected or slight model warming. Key differentiating factors include the strength and timing of the marine layer and any weak frontal passages, which can suppress highs by 3–5°F through reduced insolation and evaporative cooling. Recent pattern evolution—from record warmth in mid-June to the current trough—has anchored expectations in the cooler range, with limited volatility until the next NWS update or high-resolution model runs refine cloud and wind forecasts. Market-implied odds align closely with this evidence-based outlook while embedding realistic uncertainty from typical short-term forecast spread.
