Persistent high pressure and clear, sunny conditions over North Texas are sustaining extreme heat, with official National Weather Service and local forecasts calling for a Dallas high near 105–107°F on August 22 under light southerly winds and minimal cloud cover. Recent model consensus shows limited variability, consistent with the past week’s observed peaks of 106°F and the region’s climatological tendency for late-August maxima in the mid- to upper-100s when subsidence dominates. Traders have priced the 104–105°F bin highest at 51.5% implied probability, reflecting this stable thermal setup, while the 23.5% chance assigned to 106–107°F accounts for any slight upward bias in afternoon mixing or insolation. Updated short-range guidance expected overnight will test whether steering patterns or boundary-layer moisture shift these odds before resolution.
