We will take a look at the NAM model to breakdown the timing. Snow will begin to overspread the area from south to north between 9 PM Monday through midnight Tuesday, below is the NAM valid 11 PM Monday night:
By 2 AM Tuesday Morning much of the state is in steady to heavy snow, by this time driving is highly not recommended:
