While individual cells may be visible, hail is not very reflective, is notoriously difficult to detect with radar, and can be found miles downwind from weather systems. It can be a VERY surprising encounter as you may be clear of the weather by miles and suddenly encounter hail.
Two years ago I was at the local airport and we had a massive storm build up just west of us and pass through. I was inside a C-47 inside of a hangar with ear buds in listening to music while cleaning while the hangar door was partly open. It went from being relatively bright outside to whiteout with just hail in an instant. We had hail falling a good 5 minutes before the first drop of rain even fell. The Hail was big too, biggest I found was golf all sized. (We had so much hail dumped, that I could no longer hear the music in the hangar at full volume, I had $5k worth of damage to my car, our fabric controls on our C-123 had a few holes in it, and we still had hail on the ground the next day. it was just spectacular).

Not sure how flightaware works in terms of radar - does it those the most recent image when the plane lands, or as it passes a given point? I honestly don't know how they come up with the imagery once the flight is over, but could it have been that the cell just to the north of the flight path is what they flew through? Otherwise it could have been hail thrown from the storm cell. Again, didn't take much time to look at the scaling, but they do look pretty close to it.
From my own flights, I have noticed the radar keeps updating for some amount of time after you pass a given area as I have seen a couple of my flights this summer show me flying my Cessna 310 right through red. Now it is possible, that it could have been "red" below me and that is return they are showing, but I know I have never flown through any of the cells flightaware has showed me flying through.

Storms can't really develop "instantaneously". They can develop quickly, but it's not instant or without notice. Pilots have warning that conditions are favorable for a storm, and in this case the pilots appear to have known that they were trying to punch a hole through a group of cells.
I remember one storm while I was working at the flight school that I had to call back the entire fleet that was out. I watched a cell develope from nothing into a 40,000ft cell in a matter of 15 minutes.
