What's generating these repeat events?
This is not a 100% rule of thumb, but when you get air upper zonal due east west, that is normally a harbringer of normal or calm weathers that outside of winter lend themsleves to precipitation that normally are thermally driven. Like those afternoon showers that spring up after the clouds billow up. And normally under these conditons, severe weather doesn't happen.
OTOH, in late Spring and early Fall if you see dips in the jet, that does two things.
(1) Those swirls of intermixing of the zonal flows and polar like flow spin up low pressure systems
(2) Those swirls of intermixing of zonal and polar flows also create increased temperature differntials in the air masses, that give even more uplift. When you see those examples of significant uplift, that is when you get your bad storms, hail, and tornadoes. And if it happens to be in a area of (1) that amplifies the updraft.
There are cases like with just dry lines, where there can be very little temperature variation, but if two bubbles of dry and moist air clash, you can get the same. This mostly happens in the southern plains, where we often can get twisters without a front.
Long answer, but to your question, and watching the GFS models, we are seeing much of the same of angular dips in the upper jet until mid month. Then thing look more zonal then But again, the GFS isn't always right
