The event is starting with rain into Cornwall but the MetO has taken
Cornwall out of its snow warning, leaving areas to the east of
Cornwall at risk. It'll be interesting to see if the rain turns to
snow over Bodmin Moor. Temperatures at 0.2C, with a dewpoint of 0.1C

Marginal snow there, but on the higher moor and on the A30 perhaps
rain turning to snow about now? The rainfall radar is a peach! Very
marginal whether I'll get my promised snow! *))
