Why are people over analysing the charts for tomorrow and what the met app on their phone shows, the forecast for tomorrow is changing frequently, the one I've just seen on bbc news channel is different and not as good for some parts of the west country to the one this morning and I've no doubt they'll change again between now and tomorrow morning.
My advice, sit back and enjoy the ride, if you see snow then great and If you don't then oh well, plenty of time left and the post earlier by Tamara in the mod thread sounded very interesting for the future.
