**Persistent high pressure and clear, sunny conditions under a strong summer ridge are sustaining extreme heat across North Texas, with official National Weather Service forecasts calling for afternoon highs near 104–106 °F on August 20.** Recent days have already produced readings of 102–106 °F, including a 106 °F peak on August 17 that tied the year’s high, keeping an Extreme Heat Warning active through midweek. Low-level southerly flow, minimal cloud cover, and dry boundary-layer air are limiting mixing and allowing surface temperatures to climb efficiently, while model consensus shows little change in the synoptic pattern through the 20th. This setup places the 104–105 °F bin as the highest-probability outcome in the market, with the secondary 106–107 °F tier reflecting the upper end of forecast uncertainty and any localized urban heat-island effects. Updated NWS and high-resolution model guidance released in the next 12–24 hours will be the key near-term catalyst for any further shifts in implied probabilities.
