Your expectations have materialised as I have to hand a rainfall total
from the Isle of Wight, narrowly exceeding the Portsdown Hill figure.
At Wootton, 5km NE of Newport and 5km W of Ryde, 44.9mm
of rain fell between 2100 and 0900Z most of which occurred during
the storm from 0330 to 0530Z (approx).

Here in Romsey, I emptied 'just' 18.8mm. Unlike Wootton, however,
the thunderstorm merely produced slight to moderate intensity rainfall,
following a period of very heavy rain and a gusty northwest wind (that
awoke me) without thunder, although lightning was visible southwest.
As the heavy rain eased at 0320Z, the first rumbles could be heard,
finally out of earshot by 0515Z.

Most of the overhead activity was medium level (AC cas) producing
a fair amount of CC flickering and long drawn out noises, but lower
bases (CB) and more of the direct CG strikes were evident towards
the south.

My Friday (midnight-midnight) total for Portsdown Hill was 51.3mm. 47mm fell
between 0430Z & 0600Z.
