I'm hoping against hope that the snow skirts 'round us, with minimal accumulation/disruption, but I realise that is extremely optimistic (unrealistic?) based on the current forecast.
Do I go ahead with the party no matter what? At what point, and under what conditions do I consider cancelling/postponing? Eeeeeek!!!
We're in central London, and the party is after school at a hall with entertainment booked, cake bought, food purchased, etc....
