Why not, they are in the UK?

Agreed but they're hardly representative.


Each station is only representative of the station itself. I drove to
Wattisham one Sunday just before the start of my night shift (00Z
start) along frosty roads with fields and trees heavy with hoar-frost.
This disappeared a few yards from the main gate and I arrived at the
office to find Honington had no frost or icy-road warnings in force for
the area. They'd misguidedly been going by our Wattisham obs which
bore no relevance to the local area whatsoever. A light-vessel in the
North Sea would have been as much use. As I recall, our air min for the
night was +3C but I guess it was closer to -3C within a few hundred
yards of the base when I'd arrived for work!

Several nights Wattisham had visibilities of over 20km when everywhere
else in East Anglia was no more than 2.5km in mist or industrial haze.
One night we had persistent cloud at 100ft or on the surface when the
whole UK had no cloud below 3,000ft at any time and, before anyone
asks, it wasn't upslope St.
