RMK: Noticed shallow fog forming over wet grass shortly
after 18z, and it appears to have been foggy for most of
the night, although vis was very variable. Vis improved
sharply from 200m to 2000m+ while I was doing the ob
with cloud down to 3 okta and strong sunshine briefly, but
it closed in again as I walked back. We appear to be near
the top of the fog. No higher cloud was visible. 0.2mm
fog drip overnight; and a high grass min characteristic of
all-night fog.
