Do I still go to my drivers test if it snows/ices?

I live pretty far up northwestern in NJ, my driver's test is in Wayne. So if it snows/ices on that day do I still go? It says for the 25th, it is supposed to rain/snow/ice. I hope it changes because I am fuming mad right now, and I have waited for this day forever, and I refuse to have weather ruin it!
