Benson/EGUB often experiences very cold overnight temps in winter with a slow-moving high pressure system, and yet there seems to be no short/long term memory of this in the Met Office. I have noticed when the high is barely moving for days that the min overnight temp forecast twelve hours ahead is 5C higher than that subsequently recorded, even when the night just gone was similarly cold.
Garbage in Garbage out springs to mind, but perhaps they are just stupid
