I don't want to see the pna too positive or see it too negative. That's why it's very difficult to get winter weather in the south

We tend to score at the end of +PNA patterns. A spiked +PNA really helps if we get energy diving out of Canada or the PNW, but generally we tend to score after a period of +PNA and as we are trending to a neutral. Too much west coast ridging, especially coupled with a -NAO and we just send the freezer down here and end up with sunny and 25 degree days. Very very fine line

Always very difficult here. Get cold established and take our chances from there
 
Guys a spiked PNA is always is a good thing. Let me pick only one TC and a posotive PNA is always numero uno! #2 is atlantic blocking, -nao's an 50/50 lows etc, to slow flow and lock the cold air coming down out of canada in. We will get the ns energy this winter with a + pna , no problem. Problem will be hunting some ss energy to generate a phaser or two. Expect a lot of upslope snows this year, esp first 2/3 rds of winter . Aka, have the Jimmy roadtrip plan developed on standby. After about 4 or 5 downslope screw jobs, just take a 90 min trip up top.

IDK. I guess my biggest thing with the PNA is just don’t let it be strongly negative and I’ll take my chances with cold close by and strong blocking up north. Some of the best storms I’ve gotten to experience, including February 2004, and the 2010 Christmas storm, took place with a -PNA. While I’ve seen so many times a strongly + PNA suppress everything way south and we end up cold and dry.

According to multiple studies of NC winter storms, of all the indicies, a -NAO is the most common thing in place. I’m not saying a +PNA is bad, I’m just pointing out that there have been a number of great storms that saw a neutral or slightly -PNA
