"Avengers: Endgame" memes? Pshaw! "Game of Thrones?" Pretender to the crown. When it comes to endangered species memes, nothing works better than the cannon fodder that is the redshirted Star Trek crew member.
Things don't look all that bad tomorrow, though. At least at this point. But given the benign nature of the severe weather season thus far, the hint of some high end severe weather tomorrow gives us pause.
Okay, we paused. Now, prepare for severe weather. It COULD start as early as later this afternoon, although the Storm Prediction Center has calmed things down today somewhat. Looks like flooding could be the big ouchie tonight (extending through Wednesday).

We see a flash flood watch for tonight across NE OK, but I wouldn't be shocked if that extends farther to the south and west eventually.

SPC "only" gives us a marginal risk across most of the state for today, with pretty low chances for anything significant in the way of wind and hail, and twisters.

Tomorrow still looks to be the most significant day, with Wednesday another "wait and see, could be bad" day.

There's no way to give absolutes on this. SPC will issue new outlooks later just before noon, and things could change a bit, change dramatically, or stay pretty much the same. That's the way these severe weather days evolve. What happens today could have a big impact on tomorrow, and then again on Wednesday. Where will the boundaries set up? What will happen to the capping inversion? Will we hit the magical temperature to initiate convection? And that's just the basic stuff. At the least, I'd say prepare for lots of rain starting tonight, with wind and hail a possibility to add tomorrow, but don't rule out a high end severe weather day tomorrow just yet.
The 3-day rainfall forecast shows the flooding threat pretty well, but even that is being too particular. Where will those storms line up and repeatedly train over the same area?

All these reasons and more to PREPARE NOW for the next few days. Or at least put on a gold or blue shirt.
