**Current National Weather Service forecasts and model consensus indicate a Thursday night low in the low-to-mid 60s for Dallas, driven by a cold front shifting winds northerly after sunset on October 15.** This produces the primary catalyst for trader positioning, with leading market-implied odds clustered near 31–32% across the 63°F-or-below, 64–65°F, and 66–67°F bins reflecting residual uncertainty in exact overnight cooling rates. South-to-north wind transition, increasing to 10–20 mph with gusts, enhances mixing and radiational cooling under partly cloudy skies, while dew points near 60°F limit further drops. Historical October climatology supports lows in this range during frontal passages, though model spread in boundary-layer moisture and cloud cover keeps probabilities balanced rather than concentrated on a single outcome. Updated NWS guidance and evening model runs will provide the next resolution signal before the market closes.
