Yes indeed, there's always a fly waiting in the ointment. I'm not worried about what the models are showing for the NAO until we get into early/mid-December. However, as a general rule, I don't care for very high or very low QBO values during the winter. But that concern may be silly, since I don't understand it all that well. Also, to add to my uncertainty, no matter what the QBO value is, there is always a camp stating that it won't hurt and an opposing camp saying it's completely disastrous. So, I end up hoping for something close to neutral.
