I have a colleague who claims that it snowed in the Doncaster region on
26 September 1991.

I think this is most implausible, even on high ground. I know September
1991 was a warm month overall, but it had a cold, unsetttled spell
around the 26th - but not that cold.

Please tell me that I am right.

Trevor - I think you are indeed correct. I see a maximum here of 13.0C
following a min of 6.7C. It was cool but the 850 mb temp was about +2C in
that area, so the melting level would have been well above mountain tops.
Just possibly the Scottish mountain peaks would have seen some sleet/snow
showers. Could the "snow" have been graupel - soft hail? Even that seems
unlikely to me.

I have a max of 11°c (no min, sorry) and thunder for that day, so it looks
as if it was more likely to be hail rather than snow
