Just been browsing recent METARS and found this for Benbecula:

EGPL 312120Z AUTO 02008KT 9999NDV FEW020/// SCT033/// M28/// Q1013

I know it's been very cold north of the border but an air temperature
of -28C? - can't be credible surely!

No, and especially not for Benbecula, which from its location ought to
be one of the least cold spots in Scotland. I expect that somebody had
finger trouble when typing it into a computer (I assume that the logging
is all computerised these days).
