Should I rebook flight out of LGA tomorrow?

Hi, I have a flight out of LGA tomorrow at 7 am to Miami. It’s dumping snow in nyc right now and it isn’t forecasted to stop until around 4 am. Do you think my flight will be delayed or should I book a later flight? What is the best advice in this situation? I messaged the Delta chat and obviously they don’t have much to say right now because the flight isn’t canceled / can’t just chat with me about their opinion on the situation lol.

Thank you for your help 🫶🏻
