@Arthur5707d "Resolves YES if any amount of snow falls from the sky...[on dec 25th]." That makes it clear that it was about precipitation during the 25th and not the snow on the ground.
@Arthur5707d Definition: "Total Precipitation (mm)
The sum of the total rainfall and the water equivalent of the total snowfall in millimetres (mm), observed at the location during a specified time interval. (See climatological day)"
I see a total precipitation of 0 for December 25th. Is snow on ground accumulated or snowfall for the day ? Their definition is not clear on that point.
@Arthur5707d Thanks for the fix and having a clear resolution criteria. I learned a bit on how weather data is collected and managed along the way.
