Forecast models from the National Weather Service and private sources show Seattle under building upper-level ridging Monday, with clear skies, light northerly flow, and dry air promoting efficient overnight radiational cooling. This setup favors a minimum in the mid to upper 50s, aligning with the market's clustered leading outcomes near 55–58 °F and the climatological average low of 56 °F. Subtle differences among 54–55 °F, 56–57 °F, and 58–59 °F bins reflect minor variations in model guidance on boundary-layer moisture and exact wind speeds, while lower-probability tails account for possible patchy smoke or slightly stronger onshore flow. Updated NWS discussions and evening model runs remain the key near-term catalysts.
