RMK: 1Cs way to the S and SE, also 1Ci to the NNE,
otherwise sky clear. Thick haze across the Vale of Aylesbury
but haze layer is fairly shallow, probably not extending much
above observation point. Ground frozen, hoar frost now
"lifting" in the sun. Some condensation in the rain-gauge
funnel which wasn't there on recent mornings.
