I'm afraid it's not looking good. The latest charts have the next low coming down across the country this weekend stalling over the south west, where it will start to pick up warmer air from the south before moving back up over the country. :(
The build up to Christmas is looking to be a very cold one from the latest GFS charts. Both time's I've looked today (two different runs) have said the same thing. Will be interesting to see if the next one says the same.
