Often, no matter what weather server I choose on my phone, the daily precipitation probability is lower than several hourly ones.
For example, right now, on Foreca, the "daily precipitation probability" is 10% for my location.
But the "hourly precipitation probability" is 21% at 6 PM, 18% at 7 PM, 16% at 8 PM and 11% at 9 PM.
That seems like a statistical impossibility. The daily should always be at least equal to any given hourly.
Can you explain this?
Thanks in advance.
