I wouldn't be so sure Len.
Turned decidedly sleety in Penzance in a very heavy burst just before the clearance. Certainly sleet rather than hail, all sliding down the conservatory roof. The temperature dipped to around 4C around 13:30, but the dewpoint is close to freezing and the rain drops were very large. Below 3C @ Cardinham at 14:00.
The recent showers have suggested wintry precipitation melting very close to sea level. Take a look at the 14:22 webcam image here.
