RMK: Hoar melting patchily, overnight rime falling off trees,
and strictly speaking it's now a wet fog rather than a freezing
one. Blue visible at the zenith, vaguely bright where the sun
is, although it's a long way from being visible. Top of the fog
prob somewhere between 260 and 280m amsl. Ground
frozen hard

RMK: Still a hint of blue at the zenith, and the sun's disc
is intermittently just visible.

RMK: Enough wind now to make it feel really cold all of a
sudden. Still blue just detectable straight upwards.

RMK: Vis may even be slightly less than 60m. The fog is
riming quite well, and the daytime moisture has turned into
a slight glaze on all hard surfaces. Nasty. No stars visible
even directly above, suggesting top of fog has now reached
at least 300m amsl. General vis in Luton this evening 100-
300m, but in Dunstable 100m or less.
