Correct me if I'm wrong but the following statement is false?
Jonathan Powell, senior forecaster with Positive Weather
Solutions,
said: "The Scottish record of -23C in 1919 will tumble before
the year
is out."
The actual record as far as I know is minus 27.2 °C (-17.0 °F)
1995-12-30[23] recorded at Braemar (1895-02-11 and
1982-01-10 ) and
Altnaharra (1995-12-30)

The assertion that -23C is the Scottish record is certainly
erroneous. I remember reading the reports about -27.2 in both
Braemar and Altnaharra.
