Official National Weather Service observations recorded a maximum of 48°F in Denver on October 14, 2026, aligning with the market’s near-certain 48-49°F outcome. A strong cold front arriving that day ended an extended warm spell, bringing steady rain, fog, and north winds that suppressed daytime heating well below the 66°F seasonal normal. Model guidance and real-time surface data converged on this reading from the primary airport station, leaving little room for alternative thresholds. Minor revisions in final quality-controlled datasets remain possible but are unlikely to shift the daily high outside the 48-49°F bin given the consistency of preliminary reports.
