Most likely it's typical supply & demand. They are projecting low demand this weekend so they'll drop prices so they can move some cars off their lots. This isn't uncommon. Last weekend at RDU was the opposite: I booked 3 weeks prior and got a rate of ~$100. As the weekend approached, rates went up over 50%.
