I could not help overhear a
conversation between two woman who were saying it was too cold to snow.

Never mind "too cold". Most of the times I hear that it's actually not
quite cold enough. To be fair, I've never heard a forecaster say or even imply
that it was too cold to snow.

Did they not remember January 1987 when snow was falling at minus 8C in
my area.

No, they wouldn't. I've come to the rather sad conclusion that unless
someone is really interested in the weather they never learn a thing from their
own observations but are content to fall back on ideas they acquired when very
young. Great tact is necessary in pointing this out to neighbours, etc. Down
the pub it's different.
