County-days per matrix position
Data: Flood Forecasting Centre Flood Guidance Statement, per-county five-day export, archived on each issue (~10:30 UK daily, occasionally twice a day). Columns are aligned by valid date, so each day of the later issue sits directly beneath the same day of the earlier one. Comparisons need at least two overlapping days.
