National Weather Service forecasts and supporting model guidance place Dallas's October 15 high in the upper 80s to low 90s, driving the market's tight clustering on 88-91°F outcomes. Sunny skies and southerly winds of 5-10 mph will sustain warm advection ahead of a cold front, with afternoon temperatures peaking near 88-90°F at official reporting sites before northerly flow strengthens overnight. Minor model spread in boundary-layer mixing and exact frontal timing creates the narrow gap between the two leading bins, while historical October averages near 80°F underscore the anomalous warmth. Updated NWS briefings and next model runs will refine resolution criteria ahead of market close.
