National Weather Service forecasts and model consensus point to persistent high pressure and sunny skies driving Dallas highs near 106°F on August 21 under an Extreme Heat Warning, following multiple consecutive days at or above 105°F amid a 35-day dry spell. Low humidity and light southerly winds limit mixing and cooling, while a 20% afternoon thunderstorm chance poses minimal risk of suppressing peak readings. Historical August 21 records top out at 107°F, and current conditions align with near-record potential, explaining why market-implied odds center on the 104-105°F bin with secondary support for adjacent ranges. Afternoon observations will resolve the market as data updates refine the exact maximum.
