**Current National Weather Service and model guidance indicate a minimum temperature near 66°F for Dallas on October 9, driven by persistent high pressure, clear skies, and light easterly flow that limits nocturnal cooling.** This setup favors the market's leading 66-67°F outcome at 51% implied probability, as dew points in the upper 50s to low 60s and minimal cloud cover support radiative cooling to the mid-60s rather than deeper drops. Recent warmth from a southern ridge has kept readings several degrees above the 1991-2020 average low of 61°F, with no cold front or significant advection expected through the period. Traders price in modest uncertainty around model spread and local urban heat effects, reflected in the near-50% odds on 57°F or below and warmer extremes, while historical October variability underscores how small shifts in wind or moisture could alter the exact minimum. Updated NWS forecasts and evening model runs will provide the next key data points ahead of resolution.
