**Current forecasts from the National Weather Service and local models indicate Denver's September 29 high will likely fall in the upper 60s to low 70s°F, aligning with the market's concentration of probability around 68–73°F.** A passing weather system has brought increased cloud cover, light rain or drizzle chances (20–50% in most guidance), and northerly flow that limits daytime heating and solar insolation. This setup has suppressed temperatures below the long-term September 29 average high near 71°F. Ensemble guidance shows a median in the mid-to-upper 60s with a plausible range extending into the low 70s if breaks in the clouds occur, while downside risk remains limited absent unexpected clearing. Official updates from NWS Denver/Boulder and model runs through the afternoon will refine the exact maximum before resolution.
