Unreal clouds layer

Hello guys, i found about FSRealWX today and i decided to give a try. I was using P3D V2.4 and download weather from internet. So far, so good.

The problem started to occur when i decided to climb, the transitions from one cloud layer to another was very abrupt and there was clouds layer at 55000ft and above.

The metar that the program was using was SBRJ 042100Z 17009KT 9999 FEW015 BKN090 26/22 Q1012. So maybe something with the interpolation went wrong.

Thanks,
Eduardo
