Current forecasts from the National Weather Service and other models point to a Seattle high on June 6 in the mid- to upper 50s Fahrenheit, driven by a strong marine layer and onshore flow from cooler Pacific waters that limits daytime heating. This setup typically caps temperatures well below the early-June climatological average near 70°F, with cloud cover and possible light showers further suppressing the peak. Model consensus favors readings in the 56–59°F range, though small shifts in wind direction or marine-layer depth could push values a few degrees higher or lower. Traders appear to weigh these near-term atmospheric conditions heavily, as the market’s tight clustering around the leading outcomes reflects uncertainty in exactly how the boundary layer evolves overnight into tomorrow.
