I have watched these threads with fascination and finally caved and created an account. This is a field I know nothing about, but involves snow, which I love. I moved away from Baltimore for 13 years, missed all the great snow storms and seems I moved back during the 6-7 year lull, and have watched wave after disappointing wave drop virtually nothing. So, give a complete idiot some guidance: at what point should I actually get excited? 6 hours out? 12? Sleep until the Governor declares a State of Emergency?
