So we have will it snow/won't it snow this weekend now 
The answer is probably yes, in places. Perhaps some over Scottish mountains Thursday night, then Friday night it could cover further south into northern England and Welsh hills. Snow showers though, so some may escape any precipitation at all.
Saturday I think the greatest areas at risk are down the East coast through to Lincolnshire. Perhaps parts of Norfolk too. However, many areas could be at risk, so I guess, be prepared.
It is going to be bitingly cold with the met office going for sub zero 'feels like' temperatures in the middle of the day even in the south.
Snow forecasting is when it gets really difficult. Hard enough to predict exactly which areas will get a rain shower on a showery day, people tend to really notice when you get snow wrong! This is where I also remind people I'm purely an amateur and its best to take what I say with a huge pinch of salt as I do get things wrong!
