NASA TV coverage underway, Propellant loading on hold due to weather 

The launch team is ready to begin loading propellant into the rocket, but they are holding due to a small weather cell that is producing lighting. Weather criteria for tanking stipulate that the probability of lightning must not exceed 20% in the first hour of tanking. The team is prepared to proceed with tanking as soon as the weather issue is no longer a concern.
