So the “gaffes” turn out to be predictions that things are going to be warm, when they turn out to be cool. (Gee, I wonder why they would make a mistake in that direction.) Then, when they have an inkling that things really are likely to be cold, they sit on their hands.
They just can’t bring themselves to predict colder anything. It isn’t PC for a liberal.
I guess the Met Office needs to figure out that politics and weather prediction are like oil and water.
