Current forecast models from the National Weather Service and ensembles indicate Denver's September 3 overnight low will likely settle in the low-to-mid 60s°F under clear skies and light southerly flow, driven by a strong upper-level ridge promoting subsidence and minimal radiational cooling despite the early-fall date. This places the outcome well above the 1991–2020 climatological average low of 54°F, with trader sentiment split between the 72°F+ bin and sub-54°F bin reflecting lingering uncertainty in model runs for boundary-layer mixing and any subtle moisture return. Historical analogs show warm early-September nights often persist when high pressure dominates the central Rockies, though a modest shift in steering flow could introduce cooler air by resolution. No major data releases or model updates are imminent before the period.
