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. ]=
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.=

1800 E F2 45km - 1/CI T306D103
RMK: [CAVOK] - 1Ci (odd patches in the distance)~300+. Sky is looking
distinctly 'milkier' now, and horizon beginning to look a little less
distinct as the wind eases down.
[ DAYTIME DATA (09Z - 18Z):
screen max: 32.0 precipitation: NIL
other data: Warmest day of the year (so far), and the warmest day since
11th August, 2003. ]=
