**Forecast consensus from the National Weather Service and private models points to a mid-50s overnight low for Denver on September 26 under mostly clear skies and light winds following Friday’s weak disturbance.** This setup favors moderate radiational cooling at the city’s 5,280-foot elevation, where dry air and calm conditions after sunset can produce larger diurnal drops than at sea level, yet recent guidance has held the minimum above the long-term September average of 45°F. Trader sentiment remains split because small shifts in cloud cover, wind, or the exact timing of drier air advection could push the low several degrees in either direction—pushing probabilities toward either the warmer or colder buckets—while historical variability on this date (records from the upper 20s to the upper 50s) underscores the inherent uncertainty in short-range temperature forecasts. New model runs and surface observations through tonight will likely narrow the range ahead of market resolution.
