Hi there! First of all, great work! Windy is definitelly my favourite personal weather forecaster.

Recently I've found the new layer on Windy showing projected rain accumulation in next 12 hours, 24 hours and so on. I'm trying to understand how this cumulative layer should match with the rain layer. For example, rain forecast for today shows quite some rain crossing the whole Czech Republic from west to the east, but cumulative rain layer shows no rain in Czech Republic for next 12 hours. What am I doing wrong here?
