The latest AO forecast is off the charts. Since I have been into the weather I have never seen it go off the charts, and for so long. This signals one thing, extreme cold. When the AO is negative it means the cold air over the poles is easily transported to lower latitudes, and it's not polar air it's pure arctic air. To me this is a precursor of nasty times ahead.
This coupled with a negative NAO sends all the cold air into our region. After this winter I don't want to hear a thing about global warming, and neither will you. Check it out, it's almost unreal.
This intense blocking pattern over the arctic circle could be due to volcanic activity injecting sulfur into the stratosphere warming it which in turn cools the troposphere. The basis behind the AO! But that's only theory...
P.S I ended my below freezing streak with 225 hours and 32 minutes consecutive. (Not bad for December)
