This one looks like high altitude convective weather build up not frontal one, you will be flying under their level anyway, so losing sight of the ground is not an issue, but always keep bits of blue sky above and plan the route around them
Flying between TS tactically is a death trap in GA aircrafts, it is not experience or equipment (stormscope, datalink, visual) that you are missing it's the SPEED, you will be doing 80kts around TS in any GA aircraft (I know some cruise at 160kts but they will slow down to 120kts yellow arcs when they wiggle and about 40kts get shafted by turbulence and windsheer), so if you do the math it is dead easy: TS lifecycle is 10min, you need to say 20nm clearance away to keep teeth and visibility, that's 120kts so you are barely moving while they pop up/down around you, you will get caught soon or latter whatever your decision making as you can't run away...
Flying under TS means precautionary landing or forced landing before you lose VMC or control, you have to cut the loss not making it to destination or even back, no point climbing above MSA to fly IFR in a CB/TS cell, but between Culumnimbus and Cumulusgranite the choice is obvious
Enjoy, they make some nice views from distance, so worth flying even if you don't make it to destination, if you do, the sun makes a nice appearance 10min after they passed at destination !
I know it is a hot day, just take more fuel
