After you mentioned her earlier I found a couple of articles. Very interesting.
Couple of years ago after the summer 2010 events here in Pigsknuckle, and working in river mechanics, I was thinking about a braided jet, similar to higher energy streams. Interesting that it is the opposite. Like she addressed in an article, what is happening is like meandering streams, a lower energy system, because the driving energy for the jet, the temperature differential between the arctic and mid-latitudes, is reduced.
Regardless, the results she described are what I have observed the last few years. The entire summer of 2010 was one system after another that would train thunderstorms every evening for three to four days. The summer culminated with a record flood right here in Pigsknuckle. The rain the evening before was not exceptional, 4"+/-, but since the two nights previous had also seen ~4" each night, everything that fell the final night was direct runoff.
May 2011 Dakotas/Montana rainfall event. Record post-regulation (dam) flooding on the upper Missouri.
June 2008 Iowa flooding.
Both of the above events, the climate just seemed to lock up all of a sudden, keep dumping rain. In general, no massive single events, but just rain followed by more rain, monsoon/saturated conditions, so by the end the total mass of every drop that fell was runoff.
