Current National Weather Service and ensemble forecasts for Denver point to a September 23 minimum near 54–56 °F under partly to mostly cloudy skies that reduce radiative cooling overnight. Persistent southerly flow and modest moisture ahead of a weak trough are limiting the clear, calm conditions typically needed for stronger drops toward the seasonal normal low of roughly 46–49 °F. Traders appear split because small shifts in cloud timing or wind speed could still push readings into the low 50s or hold them in the mid-50s, while longer-range guidance shows limited cold-air advection. The next model cycles and NWS forecast discussions will clarify whether the current mild pattern persists or yields to greater nocturnal cooling.
