Bye Bye SE Ridge ? Hello -NAO?

Good Evening

After taking the evening look at model data...I have seen something different than the cool-warm-cool signal that has been dominate for the past 45 days. Alot of the models are trying to move the intermittent SE ridge to more of a intermittent Bermuda type ridge. If this happens troughs will be able to dig further into the southeastern united states and maybe into south florida.

This happenes alot when you see a -NAO/-QBO regime start to take hold of the pattern. We have been lacking in the -NAO department as I truly thought it would have taken hold by now....but that has not been the case. Time will tell and we will see if this is just another confusing aspect or if it is indeed a true signal for sustained cold.
