BRACKNELL (TAWFIELD)
0900 WSW F2 25km - T247D172
RMK: [CAVOK] - sky clear, but a little less 'blue' than previous days -
quite hazy towards sunward horizon. Mist for a short time around dawn.
Wind a notch down on this time yesterday, and the dew point is a degree
higher, so we're in for a steamy one!

Assuming that was the same one I saw, Martin, it was even further away,
eventually spawning some showers across Cambridgeshire, roughly
between St Neots and March, though they seem to have slipped through
the NCM network.
