My rainfall data for last night's storm had obviously under-recorded the
true amount by a wide margin due to the gauges being blocked my hail.
According to David Braine on Spotlight around 100 mm fell in one hour and
on top of that there was between 15 cm and 30 cm depth of hail.

Hard to describe how much hail actually fell but imagine a hail storm
which covers the ground in around 1 or 2 minutes then let this intensity
continue for nearly two hours, with torrential rain mixed in. The sound it
made was like a continuous loud roar, coupled with dazzling, frequent
lightning and deafening thunder, something that I won't forget in a hurry.

The effect the rain and hail had on soil temperatures, especially the 100
cm depth temperature is quite remarkable and larger than anything I have
recorded before. At this depth the temperature normally varies by only a
few tenths of a degree over a week but here are readings for the last 5
days.

Date 30cm 100cm
26 11.4 11.8
27 10.1 11.7
28 8.2 11.5
29 7.0 11.3
30 5.9 7.6
