Hello,

The POP on the 10 day vs the hourly forecast for that same day dont seem to add up.

Hourly is about 20%

40% is for the day and night

The chance of precipitation for the day isn't simply a total of all the hourly percentages. The daily chance can sometimes be much greater than any individual hour's chance. But at other times, the daily percentage can be equal to the highest hour's chance.

If I completely misunderstood your point, please let me know.
