- Red bars stretching upward - show number of observations within each TMIN bin for only days of extreme high PNA, where bins are 1°F wide and centered on whole numbers
- Blue bars stretching upward - show number of observations within each TMIN bin for only days of extreme low PNA, where bins are 1°F wide and centered on whole numbers
- Grey vertical line - mean TMIN for all days
- Black dotted vertical lines - mean TMIN for only days of either extreme high or low PNA
- Black vertical lines - thresholds for extremes of TMIN for all days
