Recent National Weather Service and commercial forecasts for Dallas on September 8 project a high near 100–102 °F under persistent high pressure, clear skies, and light southerly flow. This setup favors strong daytime heating, with dew points in the low 70s producing heat indices above 105 °F but having limited direct effect on the dry-bulb maximum. Model consensus remains tight, though small differences in boundary-layer mixing or slight timing shifts in the ridge could nudge the peak one or two degrees either way. The market’s near-even split between the 100–101 °F and 102–103 °F bins therefore reflects genuine forecast uncertainty around the precise thermal maximum rather than any major divergence in expected conditions.
