[WR] Romsey - torrential rain and small hail
 

Near day darkness occurred at 1200Z heralding the
onset of intense rain accompanied by a barrage of
clear hailstones of 3 to 4mm in diameter clattering
against the windows. The hail element persisted
for exactly 9 minutes.

The SSE wind produced gusts to 36kt in the heavy
pptn, veering westerly and dropping dramatically
to just 5kt. All is quiet after that noisy spell
when the visibility plummeted to 1000 metres.

16.5mm of rain has fallen in the space of 3 and a
half hours between 0900Z and 1230Z, with over 7mm
dropping in the final half hour of that period.

The temperature has taken a modest 1 degree drop
whilst the pressure continues to fall, if more
slowly.

Currently (1240Z), the rain is falling at moderate
intensity.
