Tried doing some research on whether La Nina is a cooler or warmer winter for us. Based on previous post who I know loves cold weather it must be warmer, in theory, for our region. This would stink. Bad.

However, the graphs that I found that display typical La Nina wind flow portrays cooler/colder air that is closer and available to be tapped by a dipping jet stream, should there be one.

We certainly can't do anything about the weather but man oh man...we need a couple of solid (not pipe busting) freezes to even the score from the past 2 benign winters.
