If it's bad tomorrow I will more than likely skip it .
I've managed to get through each storm so far this winter but got caught heading home late in one of them and grinding along in deep snow I broke my chain. I do carry a chain tool and set about to fixing it in the freezing cold- the temp was close to 10f and the pin on the chain tool snapped. All this happened about 3 miles into my commute and I ended up walking the 7+ miles the rest of the way.
Sometimes it's just better to wait it out and ride another day.
