Well, snow pellets actually.

After several days with similar temperatures, sunny periods & mainly
light winds
Min Max
15th 5.3 8.9
16th 4.4 8.3
17th 3.9 8.0

The wind really picked up (Force 4-5) last night. The temperature
dropped to 0.8C, but was back up to 3.0C by 09:00, with the wind
crossing the Penwith peninsula from the north coast, rather than the
really cold ENE direction.

Being off the sea, the wind has also brought a few very light snow
pellet showers. If the wind backs slightly more we could get some
heavy showers on the tip of Cornwall, but it doesn't look like that's
going to happen.
