BRACKNELL (TAWFIELD)
0900 SSE F3 20km - 2/AC T184D142
RMK: [CAVOK] - 2Ac~120. Sky has a continental, hazy look to it.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 12.4 grass min: 09.6 precipitation: NIL [24hr total: 00.0
mm]
other data: rather more Ac cas around about a couple of hours ago - one
cell quite 'threatening', but dispersed as it moved north. ]=
1200 SE F3 30km - 2/AC T259D158
RMK: [CAVOK] - 2Ac cas~070/080, 2Ac (thin patches)~100, tr Ci~300.
Feels distinctly 'tropical'; the castellatus towers have well-developed
vertical structure, and are moving from SSW, so a good amount of
directional shear evident (from the surface): double-checked dew point -
seemed a bit high, but same value from wet/dry and direct rh dial.=

1500 SSE F3 30km - 2/AC 6/AC T278D150
RMK: [CAVOK] - 2Ac cas~070, 6Ac~090, total = 6 oktas; base of lower Ac
looking dark & 'wet', as if it would produce a few drops if the lower
air wasn't so dry. Provisional day max. 28.8°C, which is higher than
anything we recorded during August.=
