Mistake i think, no snow here in Dudley about 8-10 miles away from B'ham
city centre, about 20 miles from the airport. If not, it must have been
localised.

While it was quite chilly (+1C) by dawn at the surface the profiles
(e.g. Watnall 00Z
http://weather.uwyo.edu/cgi-bin/soun...400&STNM=03354 )
didn't support precipitation, let alone anything frozen.

Looking at the sequence I suspect some moisture was being deposited due to
the fog and the automatics registered this as snow between 0150Z and 0250Z.
The then derived recent snow (RESN) got left on the manual ob at 0420Z
