**Forecast consensus from National Weather Service and major models centers on a daily maximum of 106–107°F for Dallas on August 23, 2026, under mostly sunny skies, light southerly winds of 5–10 mph, and low humidity.** This aligns with the market’s strongest outcome at 53.5% implied probability. Recent model runs and early-morning observations show temperatures already climbing through the mid-80s to low-90s by mid-morning, consistent with a continuation of the multi-day heat wave that produced 105°F on August 22. Key drivers include persistent high pressure maintaining clear conditions, above-normal seasonal warmth (historical average high ~96°F), and minimal cloud cover or precipitation risk. The all-time record for the date is 107°F (2010), providing a tight historical bound that caps upside while supporting the 108–109°F bin at 19%. Traders appear to discount lower outcomes (104–105°F at 26.5%) given the strength of the current ridge and observed trends, with negligible probability assigned to extremes outside 104–109°F. Updated afternoon observations or any unexpected boundary-layer mixing could refine the exact peak, but current data lock in a narrow, high-confidence range around the forecast high.
