I may not be that much of an expert (nor do I play one on TV, and have not stayed at a Holiday Inn Express)...but my 2 copper coins worth: The "main" southern stream trough actually has a neutral tilt (aligned more or less north-south). The northern stream energy up around WI is neutral to slightly positive tilt. But it sure looks like it's getting close to phasing with the southern stream...which, if it did, would probably result in a closed off system that becomes negatively tilted.
(Note: "positive" tilt, trough aligned more southwest-northeast in the flow..."negative" tilt, aligned northwest-southeast, and can become closed off..."neutral" tilt, aligned more north-south. Generally speaking, a positively tilted trough is weaker, and the energy can tend to get sheared out. A negative tilt or closed low implies a slow moving or intensifying system, or perhaps phasing if there's more than one stream...these tend to be much stronger. A neutrally tilted trough is kind of, well, neutral or "in the middle", could imply a trough that's amplifying and potentially can become negatively tilted.)
