According to NASA, 'Cumulus clouds and lightning violated rules for launching Endeavour because of weather near the Shuttle Landing Facility. The runway would be needed in the unlikely event that Endeavour would have to make an emergency landing back at Kennedy. Endeavour's next launch attempt is 6:51 p.m. EDT Monday. NASA TV coverage will begin at 1:30 p.m.'"
