A late winter push is the perfect ingredients for a active Dixie Alley severe season. She should start to crank up on the next few weeks.
Well what is the perfect set up for severe weather in Dixie Alley? I always thought that was it, the fight between cold and warm. Cold fronts moving south with warm gulf moisture running north.Not really. A late winter push for the east generally means a +PNA.
The persistent Aleutian ridge has afforded us the first legit -PDO since 2012, coupled w/ the much warmer than average Gulf of Mexico, the low frequency pattern looks more conducive to tornadoes than normal.
The whole cold vs warm thing is very simplistic. To get the strong severe weather setups you need a persitiant SE ridge and a rather broad one at that to pump in moisture which would be the end of winter.Well what is the perfect set up for severe weather in Dixie Alley?

Count that a blessingTornado season appears to be changing just like our winters. To me, it seems like they occur more frequent but are weaker. Growing up it seemed like every spring we could produce a violent tornado near Davie County NC but the past several years nada for areas south of Winston/Greensboro.
