BRACKNELL (TAWFIELD)
0900 WNW F2 2500 BR 1/SC/SMOKE T-009D-021
RMK: Not too sure about the Sc - a large component must be elevated
smoke ex. the explosion at Hemel Hempstead: not nearly so concentrated
now. Also present 1 okta cirrus. Moderate hoar frost deposits present -
some surfaces icy.
[ OVERNIGHT DATA (18Z - 09Z):

1200 WNW F1-2 9000 BR FU 7/SMOKE 1/SC T024D011
RMK: The character of the elevated smoke varies from very thin veils
(sun shining strongly through) to markedly dense, billowed shapes -
these latter to the north (nearer the source), where I estimate some
genuine Sc (smoke-element induced) is located. Also visible above the
smoke is cirrus - sun shining, but general light level much reduced from
what would be expected this time. Can smell smoke in air (and we are
some considerable distance away).
Source of smoke can be seen clearly now with thick smoke plume rising
and shearing southeast, before being picked up by the lower-tropospheric
flow and feeding the general smoke veil overhead. Like something out of
'Lord of the Rings'!=
