Thundersnow very rare

Diary readers might be curious about the combination of thunder and snow we are experiencing this morning.

It is a very rare occurrance, but is not unknown even in these islands (though your editor must confess to not having experienced it before).

Aptly called 'thundersnow', in the US only six occurrances are recorded on average each year.

This one in Kent, England last year, happened during a BBC TV interview recording.
