In Florida, we get thunderstorms all summer long. The ATC here are top notch, and can seemingly thread a needle through the storm cells, and find a generally smooth ride.
My airline has provided us pretty good guidance on operating when there are storms by the field. One thing we like to do is carry a comfortable amount of fuel for the inevitable hold. (8-11,000lb of planned arrival fuel is not uncommon for an afternoon arrival in an A319/320/321). That being said, if there's a large cell on final, we'd rather land with a tailwind, with alternate missed approach instructions, than fly under the red.
