Persistent extreme heat across North Texas, driven by a strong subtropical ridge and southerly flow, has kept overnight lows in the low-to-mid 80s, with official forecasts pegging the August 21 minimum near 82–85°F under mostly clear skies and minimal mixing. Recent model runs show only slight variability from isolated evening convection or minor wind shifts that could nudge the low a degree or two, while the absence of a frontal passage or increased moisture keeps values well above climatological normals. Trader consensus therefore clusters tightly around the 80–87°F range, reflecting high confidence in continued elevated minima amid the ongoing heat wave.
