Recent National Weather Service and model guidance for Atlanta on August 22 shows closely competing scenarios for overnight radiational cooling under varying cloud cover and a possible weak frontal passage, driving the near-even market split between the 72–73 °F bin (44.5 %) and the 61 °F-or-below outcome (43.5 %). Ensemble members diverge on boundary-layer moisture and wind speeds after sunset, with drier, clearer solutions favoring stronger cooling toward the lower range while lingering clouds or a modest southerly flow keep lows nearer the seasonal 70–72 °F norm. Historical August minima rarely fall below 65 °F without organized high pressure, adding uncertainty that traders weigh against the next model runs and evening observations.
