RMK: A bizarre morning. The extensive fog in the Vale of Aylesbury,
stirred up by strong sunshine, has been drifting over the top of
the Downs under the influence of a barely perceptible NWly flow
(presumably decoupled), but the fog has only reached the adjacent
field to the W of here where the vis is 80m or less tho' the sky is
still blue. Vis at least 4km to the E.

RMK: Fog came and went several times up to 1200z;
looks foggy still in the Vale of Aylesbury from the Downs.
