TEMPO 1124 4000 +TSRA BKN050CB

The difference is very small with both being eminently flyable.

But the conflict is minimal and would not have thought it would
interfere with any aircraft movements in any way.

Don't agree Paul (or maybe I have misunderstood what you were saying)

+TSRA BKN050CB would have been enough to stop me taking off when I was
a professional. I recall an evening like that at Dusseldorf. 32 out
of 33 aircraft on the ground refused to take off. Air Traffic Control
kept saying that the airfield would close at such and such a time, yet
we 32 captains would not be pressurised into taking off in those
conditions. Of course, ATC relented after the storm had cleared and
we all got away safely, albeit late. Better safe than sorry.
