Material mistakes are documented, not buried.

Missing snowfall was displayed as 0 inches

Affected: cities whose temperature station lacked usable snowfall normals.

Correction: missing snowfall is now null, displayed as unavailable and excluded from rankings. The updater also searches for a separate snow station.

Recent multi-month average used the ending month’s normal

Correction: every observed date is matched to the normal for its own calendar month before the period departure is calculated.

Electricity price could be read as a city utility rate

Correction: city pages now label the input as an EIA statewide residential average and show its source period.
