A Very Active Last 10 days of March?

Over the last couple of days the 8-14 day analog have been increasingly pointing to an active period across the Plains and into the Midwest.
So I took the top four years on the list and looked up the storm reports centered on that date. As you can see by the examples below a stormier period could be on the way.  



 
 Storm reports and the overall weather pattern looks to be changing to a more trough, ridge, trough. However by looking at the NAO and PNA charts below. There could be an unfavorable trough off the east coast disrupting the streamline flow from the Gulf. This is due to the NAO going negative and supporting a trough and low pressure development off the east coast. So this could actually keep the southern Plains capped with warm temperatures.
Time will tell but we're definitely in need of the rain down here in the Southern Plains. We currently have over a dozen wildfires just in the state of Oklahoma this afternoon.
