Narrative:

Crj was cleared for takeoff runway 5 while thunderstorm was over airport. B712 was told to taxi to runway 5. B712 was observed on proper taxi route prior to left turn on taxiway a to runway 5. I looked at WX on radar to assess thunderstorm; then crj said was aborting takeoff. I then observed B712 had missed left turn and had stopped just short of runway 5; which was why crj aborted. B712 pilot seemed confused (possibly distraction by WX) and replied he was told to taxi to runway 5. I told pilot he missed turn and runway 5 was off to his left.
