I wouldn't mind some more rain, El Niño.
There's been plenty of blocking, just the Pacific has not cooperated. Areas to the N and NE (where the blasts are) is actually warmer than avg than we are here. Teens and 20s is colder for us but for them its just a little below normal.
Its not so much the lack of blocking, its the lack of anomalous cold air. And really this period just solidified my discontent with +PNA' and -NAO. It just benefits the east and lakes. About as reliable as those drunkin PWC mets! Give me a -PNA bowling ball and -EPO
I'm not sure I buy this ... if we had blocking in the North Atlantic, the deep and cold troughs which have impacted areas to our E/NE wouldn't be so progressive. Essentially the fast flow would slow down as I understood it. Maybe I'm wrong. That has happened more than once.![]()
I don't argue the lack of anomalous cold air. That definitely has been true more than not. Here's the question though: how can the AO be so incredibly negative yet we lack that cold air in this part of the globe? One would think that even at the high latitudes of North America that they would be suffering through an incredibly tough winter. I don't think they are. It doesn't add up.
Porta the NAO is as negative in winter this month as it has ever been since 2010. Also AO is -4 SD there is blocking but the Pacific is piling up too much stuff. Also the +PNA just slides the cold air east
On lack of cold air I don't know what else to blame other than the El Nino. It pumps a lot heat into the atmosphere. Whatever the reason when you get into the monster Nino cold just doesn't like to build in Canada.
I cringe over the years following the models and busting on cold outbreaks using the +PNA/-NAO/-AO combo. 2011-2012 spooked me since on using it. Its just not as reliable as -EPO/-PNA combo
