BRACKNELL (TAWFIELD)
0900 W F3-4 50km - 1/TCU T157D146
RMK: 1Cu con (distant north - ties in with radar echoes of moderate /
heavy showers), 1Cu hum/med (local)~018/020, nothing else - deeply blue
sky, strong sunshine. Surfaces damp but drying rapidly.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 13.5 grass min: 12.7 precipitation: 5.5 [24hr total: 05.5
mm]
other data: near-continuous rain, moderate ocnl heavy (RA/+RA), between
0100 & 0430Z: moderate rain shower (SHRA) ~0730Z. Not as much rain as I
was expecting, but has brought the monthly total to 50% of eLTA. ]=

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]

1200 WNW F3 60km -SHRA 1/CB 3/TCU T174D100
RMK: 1Cb cal (distant / to E & ENE), 3Cu con (in immediate
vicinity)~028, also 2Cu hum/med~035, 3Sc~070, 2Ci~280. Other very light
showers over us in past couple of hours, but vigorous convection in
VCNTY, and some sharp downpours must have resulted.
[ Heard on R5L a little while back - report from the Notting Hill
carnival area - 'hail sufficiently heavy to set car alarms off'!]=
