RMK: Classic Stratocumulus stratiformis (extensive sheet) translucidus

between elements). We appear to be on the SW edge of a sheet across the
SE of England - convective over-turning mixing the dry air into the
sheet ought to see it break up further; it looks very thin: occasional
shafts of strong sunshine. Early very slight hoar frost but that now
gone.
[ OVERNIGHT DATA (18Z - 09Z):

other data: Hard/paved surfaces dry; soil surfaces again drying out (we
are on a sandy soil type, so this is not uncommon in extended periods of
little rain.]=


Notes:

The basic first-line format is:-
[Time/GMT]
[Wind direction .. compass points]
[Wind speed .. Beaufort force]
[Visibility .. metres / (km =10km)]
[Visibility .. significant variation/direction]
[Weather groups .. if any]
[Cloud layers .. amount/type]
[Screen temperature/T .. degrees/tenths]
[Dewpoint temp/D .. degrees/tenths]
