Rita, your crocus will be fine. Mine in Utah always had snow on them several times, and they did just fine. Even with below freezing temps, they did just fine. I wouldn't worry about them for even a second. They are tough little guys!
It's supposed to get to 62 here today, but I don't see that happening. It's really cold and cloudy, and the wind has started blowing. Tomorrow is supposed to get up to 64, but I'll be surprised if it makes it! It's supposed to rain tomorrow, so I'm hoping for some warm air today, but not holding my breath.
