BRACKNELL (TAWFIELD)
0900 NNE F3 45km - 4/CI T249D113
RMK: [CAVOK] - 4Ci~280 or higher (probably much higher in places). A
highly sheared environment at these levels, with splendid examples of Ci
floccus & strong, well extended ice-crystal trails from thicker patches
of cloud. Otherwise, strong sunshine again.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 12.6 grass min: 09.9 precipitation: NIL [24hr total: 00.0
mm]
other data: A pleasant night as the dew point is still relatively
low. ]=



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]
[RMK .. additional/plain language information]

1500 E F2 60km - 2/AC 6/CI T308D112
RMK: [CAVOK & COTRA] - 2Ac, thin/decent gaps between elements~180/200,
6Ci (highly sheared/local dense, with high COTRA element)~280/320 or
perhaps higher. The persistence of the sheared (and precipitating) Ci is
most notable - usually the situation is such that the atmosphere
'rights' itself and these clouds disperse after an hour or so, but the
sky-scape has been quite dramatic for over 6 hours now.=
