BRACKNELL (TAWFIELD)
0900 NE F3 50km - T253D132
RMK: [SKC/CAVOK] - considering the situation (length of warm/hot spell
and wind from an easterly point), visibility and sky clarity is
remarkably good.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 15.1 grass min: 11.8 precipitation: NIL [24hr total: 00.0
mm] ]=
1200 NNE F2-3 60km - T296D125
RMK: [SKC/CAVOK] - visibility OK, but distinct 'haziness' now towards N
& NE.=
1500 E F3 50km - T327D130
RMK: [SKC/CAVOK] - although clear of cloud (and still reasonably
'blue'), there are tantalising signs of high-base convection (a distinct
'haziness' at the top of the dry thermals). Also, although vis generally
good, looking even more 'brown/hazy' towards NE quadrant: with light
winds today, presumably accumulation of London basin pollution building
up.=

1800 E F3-4 40km - T309D102
RMK: [SKC/CAVOK] - sky clear of cloud, but aircraft overhead losing
distinction against an increasing pollution level. Visibility not so
good now (still fine considering the situation), with a welcome strength
to the wind turning up in the past couple of hours, nearly a full F4,
rather than a mix of F3/4.
[ DAYTIME DATA (09Z - 18Z):
screen max: 33.5 precipitation: NIL
other data: Day maximum 1.5degC higher than yesterday, and we have now
had our hottest day (any month) since the infamous 10th August, 2003.]=
