None of the opinions expressed in this post are mine, I just read what the smart people say and put all together!
Steady as she goes people, remember winter models are all less reliable compared to the summer ones, so we will have last minute winners and losers, as always. Models tend to under power the block meaning that the low pressure bumping into it will not make as much progress at it appears, I would assume that is why this predicted front has consistently been pushed further west as we get closer to the event. It is still not reliable as to where the front will exactly end up. It could continue to move west (good for Cornwall less so for the east) or it could push further east than predicted (bad for all of us here but better for the rest of the country. Also remember that the snow predictions are even less reliable.
I forget who first said it but the quote was "get the cold here, then look for the snow" well the cold is here and it looks to be staying for a while at least a week. If this weekend doesn't work out you will have to wait until Monday for the next opportunity, yes that soon!
If it does go mental then brilliant, but remember the cold weather can be dangerous, keep an eye out for the more vulnerable in your local community when you are out throwing snowballs at everyone!
