Persistent high pressure and clear skies across North Texas are driving National Weather Service forecasts for a Dallas high near 103–104°F on August 16, supporting the market’s heavy weighting toward the 102–103°F bin. Southerly flow and low humidity are maximizing daytime heating without significant cloud cover or precipitation to moderate temperatures, consistent with typical late-summer climatology for the region where daily highs frequently exceed 100°F. Recent model consensus has remained stable, with minimal revisions overnight, though small shifts in timing of any late-day convection could trim the peak by a degree or two. Traders are pricing the narrow 100–105°F window at over 95% combined implied probability given these stable atmospheric conditions.
