I had to really think hard to decide whether, in the context of my
remembered lifetime, this really was even a "cold snap" here. But I've
decided it was one of 4 days length. The average temperature was around
4C and it didn't go above 5C for the four days and two were less than
4C. It was reinforced by a few flakes of snow one day and a few bursts
of wet snow and sleetiness on another. Either side of this were seven
consecutive days of air frosts which just about clinched it.
It will be instantly forgotten by the time this month is out due to its
feebleness.
