In DFW this year it was -18c one day and two later it was 25c. That isn't normal but every year we have at most one or two periods where there is at most a week of frozen precipitation. The problem is we don't know which month it is going to happen in and it happens suddenly. Climate change made it worse perhaps, but it has been this way for at least decades. I rember waiting in line for santa it was a beautiful 22c, before we got to the front of the line it was -7c.
