Not sure what the best way to report this is, but something is wrong with the cloud forecast for Longmont, CO, USA. It has been mostly cloudy all day but most of your forecasts show it mostly clear.

Only Meteoblue has showed it cloudy today.
I finally looked at 3 or 4 other forecast sites that have ICON and HRRR forecasts and they have been showing it mostly cloudy during the same periods where Windy has it clear.
Not sure what could be wrong but it is almost like Windy is pulling the wrong data. I have only noticed this with the cloud forecast (I'm and astronomer so I pay close attention to that). I haven't paid close attention to the other forecast parameters
