compared to the normal high and low temperatures.
January 1, 2004 - May 31, 2004
The red line is the normal high
temperature for each day and the blue line is the normal low temperature
for each day.
The top of each black bar is
the high temperature for the day and the bottom of the black bar is the
low temperature for the day.
If the top of the vertical black
bar extends above the red line then the high for the day was above normal.
If the bottom of the vertical
black bar is below the blue line then the low temperature was below normal.
In early February the high temperatures
(top of the vertical black bars) was actually lower than the normal low
for the date!
