Snow is rain - just a bit colder - hail is hard :censored: rain. It all appears the same on the radar I think.
I reckon you might be in for a couple of hours of snow from about 7-ish (looking at the BBC weather website). Not sure how heavy though.
Sounds interesting for once poo ? I'm heading for another jaunt on snowblocked A74 according to radio 2 travel news ?
