Recent National Weather Service observations and model verification confirm Denver reached a daily maximum of 78–79°F on June 13, 2026, under post-frontal northerly flow, partial cloud cover, and limited afternoon insolation that suppressed typical June heating. This aligns with climatological normals near 83°F yet reflects cooler-than-average conditions driven by a departing cold front, consistent with surface station data from the primary reporting site. Market consensus at 100% for this narrow bin rests on verified instrumental readings rather than forecasts, underscoring the reliability of official climatological reports for resolution. Only an unreported station discrepancy or late data revision could alter the outcome, both statistically improbable given established NWS protocols.
