I saw that too Brian, I noticed the BBC forecasts today playing the whole thing down to 'scattered snow showers' mainly in the 'N and NE' with mostly rain and sleet from the cold front. I think the biggest event will be the cold from this and possible convective activity. I would certainly like to be near the NE, N and NW coasts on Fri night or Sat - deep convection with electrified cbs with thundersnow are possible, the Irish Sea would be the prime place too. Some think the cold front will be convective with a risk of thunder and even a tornado. As for snow...I guess we won't know until it happens...there's alot happening with this system, check out this detailed simulation which is fascinating...
