Forecast models from the National Weather Service and private sources project a Tuesday high in Denver near 85–89°F, with mostly sunny morning conditions giving way to a 30–40% chance of afternoon thunderstorms. This convective activity creates the primary uncertainty, as earlier or more widespread storms could limit insolation and cap the daily maximum, while delayed development would allow temperatures to climb higher. Recent cooling from mid-90s readings on August 23–24 aligns with a modest trough influence, and the historical average high of 85.9°F provides baseline context. The tight market clustering between the 86–87°F and 88–89°F bins (combined ~67.5% implied probability) reflects this narrow range of outcomes driven by storm timing and boundary-layer moisture rather than large-scale temperature advection. Updated model runs and real-time radar trends will refine expectations ahead of the daily peak.
