<![CDATA[Rain forecast inconsistency]]>Hello

I am looking at the forecast for the city of London
https://www.windy.com/multimodel/51.516/-0.092?51.126,-0.092,8

On a 3 hour basis, I get this

On an hourly basis I get this

Look at the rainfall for the period.
There is either an issue with the row label (which should read mm/h) or there is an issue with the numbers (3 hours of 10mm/hours) should give 30mm for a 3 hours period

This is definitely a bug in the Compare feature. I will look into this.

If You check regular UKV forecast
3h step

1h step

You will notice that Saturday and Sunday is too far to the future and forecast step changes to 3 hours. This way, rain precipitation is displayed correctly, but Compare feature simply interpolates missing data (values for hour 00Z, 03Z, 06Z and so on match, but they have different meaning - 3h rain accumulation instead of 1h accumulation) which is wrong.
