His own forecast stated:

"15th =3F 21st January
Weather
Heavy snow. Strong, at times gale force winds, easterly turning
northeasterly
and becoming breezy. Exceptionally cold, at times not above -5oC, later in
the
period even -20oC.
Confidence level A=85%."

What a charlatan.... then he claims he never said it.

What he has done with that forecast is said that Jan 2008 is an 'unusual'
month and that a 'solar change' and a procedural error of not including
certain solar factors has meant that he has had to 'shift' his original
forecast a few days later. This on its own does not save this most
ridiculous of forecasts so if you read carefully what he has written on his
website he gives himself certain opt-out phrases by liberally using the
words 'some, likely, tending, generally, at times, probably' and so on.

There is always sufficient amount of vagueness in Piers' forecasts to allow
him to claim things when they happen, and to deny he forecast them when they
didn't happen.

He will probably say that the cold weather he forecast did happen; it was
the snowfall in Scotland and northern England of yesterday. And then go on
to claim the Met Office's forecast was wrong and his was entirely right.

A charlatan? Yes, he is indeed, but a clever, devious one.
