How to Interpret the Rainfall Data
The rainfall graphs and the hourly data show the accumulative amount of rainfall for each day starting at midnight. Rainfall is shown in inches. At the start of each day (at midnight), the rainfall is zero. The amount of rainfall is incrementally added during the day and reaches its daily total at midnight. At midnight for each day, the data show a drop from the previous day’s total rainfall to zero.
