  "summary": "Figure and tables are consistent with the analysis values, uncertainty is disclosed, and the precipitation non-significance is not overstated. Warnings: the figure caption and alt text omit population, time frame, per-panel units, and metric names, and the figure shows group means rather than the central paired-difference estimand.",

      "severity": "note",
      "check": "data-to-chart consistency",
      "evidence": "Figure caption and alt text describe mean stadium-game forecast error by HRRR version and lead time with 95% bootstrap whiskers, matching the four forecast_groups in analysis.json (HRRRv3/v4 at 6/24 hours).",
      "recommendation": "None."
    },
    {
      "severity": "warning",
      "check": "figure caption completeness",
      "evidence": "The caption 'Mean stadium-game forecast error by HRRR version and lead time' does not name the population (NFL regular-season stadium-games), the time frame (2018-2024 seasons), or the per-panel units (temperature MAE in degrees C, wind MAE in m/s, precipitation Brier score). A reader seeing only the screenshot cannot confirm units or denominators.",
      "recommendation": "Extend the caption to state the population, 2018-2024 coverage, and the metric and unit for each panel."
    },
    {
      "severity": "warning",
      "check": "accessibility text",
      "evidence": "The alt text ('Three panels compare temperature, wind, and precipitation forecast errors...') names the panels and comparison but omits units, the metric (MAE vs Brier), and the direction-of-better, and does not summarize the key result (6-hour bars lower for temperature and wind).",
      "recommendation": "Add units, metric names, and a one-line quantitative takeaway to the alt text."
    },
    {
      "severity": "warning",
      "check": "visual emphasis vs analysis",
      "evidence": "The figure shows group-level mean errors, while the article's headline claims rest on paired 6-minus-24 differences; the figure is placed after the paired-difference discussion. The caption accurately labels it as group means and the paired differences are carried by the horizon-comparison table, so no overstatement occurs, but the figure alone does not display the central paired estimates.",
      "recommendation": "Consider adding paired-difference panels or an annotation so the central estimand is visible in the figure itself."

Table 'weather-forecast-horizon-comparison' values (-0.15/-0.28 degrees C; -0.08/-0.07 m/s; -0.009/-0.016 Brier; 316/739 pairs) match horizon_comparisons.",
