I just checked CWL's website and there around 15 flights that all have a delayed status. Personally, I can see many flights being diverted into BRS. I would have thought that CWL has good enough ILS to allow aircraft to land.. ah of course CWL has ILS I..that could be why they are unable to land.
I hope some of this sunshine I can see from my bedroom window is able to clear this fog!
