The 528 Thickness Line - again!
It's that time of year again when the 528 thickness line appears around Europe on the forecast surface charts - or at least those produced by the UK Met Office.
But can anyone explain why the thickness lines only appear on the charts valid for 36hrs or more ahead and not on the current ones when there are patently signs that they would be there if 'enabled'.
The Uk Met Office website only explains what they are and not when, in time, they will appear.
Cheers all
