RMK: Intermittent bursts of rain, mostly slight. Although there's
almost a complete overcast I think the precipitation is
best
described as showers due to its convective nature.

RMK: A front of sorts appears to have gone through here around
1130-1140z with a sudden drop in dew point accompanied
by a gust to about 20 knots and the start of a drop in
temperature. The max was 4.8c at 1135z. It has been falling
gradually since then. The cloud is rapidly dissipating now.
If
it stays away we'll probably have a ground frost within an
hour
and an air frost quite early in the evening.
