Trader consensus centers on an overnight low in the low-to-mid 80s for Dallas on August 22, with 82–83°F and 84–85°F outcomes leading at 48% and 45.5% implied probability. Persistent high pressure and southerly flow under the current heat wave maintain elevated minimum temperatures, limiting nocturnal cooling despite mostly clear skies. National Weather Service guidance shows Saturday-night lows near 81°F, consistent with recent model runs that emphasize warm advection and minimal cloud cover or moisture to enhance radiational cooling. Historical August baselines for the region average around 77°F, but the ongoing pattern has kept recent lows 4–6°F above normal. Any late-day thunderstorm development or subtle boundary passage could introduce modest variability, though guidance indicates low odds of significant change before resolution.
