Forecast models from the National Weather Service place Denver's July 26 high in the upper 90s to low 100s, with official guidance centering near 99–100°F under a heat advisory. Persistent high pressure, downslope warming, and mostly sunny skies support the slight market lean toward 100–101°F, while increasing afternoon clouds or isolated thunderstorms could cap readings in the 98–99°F range. Ensemble guidance shows limited spread around these thresholds because steering flow remains weak and moisture return from the monsoon is modest. Historical July climatology for Denver favors highs near 95°F, so current anomalous ridging explains the elevated odds, with resolution hinging on the exact timing of any cloud build-up before peak heating.
