Persistent high pressure and easterly flow across North Texas are sustaining above-average temperatures, with official National Weather Service guidance and ensemble models showing an overnight low near 71–74°F for Dallas on September 24. Light winds, dew points in the low-to-mid 60s, and mostly clear to partly cloudy skies limit radiational cooling, keeping the minimum well above the 1991–2020 climatological average of 67°F. Minor forecast spread arises from small differences in cloud timing and boundary-layer mixing across runs, which traders weigh when pricing the near-even odds between an 84°F+ minimum and one at or below 65°F. No frontal passage or significant moisture return is expected before the period ends, so the outcome hinges on the precise evolution of these local thermodynamic factors.
