**Persistent high pressure and strong southerly flow under mostly clear skies have positioned 106-107°F as the leading outcome with 52.5% implied probability for Dallas’s August 23 high.** Recent model runs from the National Weather Service and private guidance converge on afternoon temperatures reaching 105–108°F amid the ongoing late-summer heat wave that already produced 106°F readings earlier in the week. Low dew points and minimal cloud cover are maximizing solar heating, while climatological norms for late August support highs in this range. Traders appear to be weighting the latest deterministic and ensemble guidance, which shows limited cooling before peak heating and only a slight chance of isolated late-day convection. Updated forecasts issued this morning will be the next key input before markets close on the official observation.
