Weekend Run?

So, if you haven't looked at the weather lately, its snowing in NYC. We are supposed to get like 5-8 inches! It's crazy. Started sometime this early AM - was already snowing when my alarm went off for Terrier Bootcamp (cross-training). Given the weather I figured class was cancelled (and I was correct, it was). But, I am supposed to run a NYRR race tomorrow morning - and they say its still supposed to be snowing then. Fun. Ironically, the race is called the Snowflake 4M. Wonder on how many years its actually snowing on race day?
