A strong cold front advancing across central Texas on October 15–16 is driving the near-even market split between a minimum of 53°F or below versus 72°F or higher. Official National Weather Service guidance and model consensus indicate northerly winds of 20–25 mph with gusts to 40 mph will clear skies after any early showers, allowing rapid radiational cooling under building high pressure and yielding an overnight low near 50–51°F—well below the seasonal average of about 58°F. Minor forecast uncertainties center on exact frontal timing, residual cloud cover, and wind speeds that could moderate the drop by a few degrees. Updated model runs and surface observations through Friday night will provide the decisive data for resolution.
