Thunderstorms sweep through Valley, bringing wind, rain, power outage and rainbow

A series of storms swept through the Treasure Valley Tuesday evening, delivering lightning strikes and a power outage to Boise.

The first wave, around 6 p.m., brought little rain but strong winds and a beautiful rainbow over Boise, said National Weather Service meteorologist Les Colin. Heavier rains hit the Stage Stop area at the Elmore-Ada county line, bringing a third of an inch within a half hour.

The second wave, after 8 p.m., brought heavier rain to the Boise area, and a lightning strike downed a power wire, knocking out power to more than 560 Idaho Power customers in the area around Boise Spectrum Center, the company reported. By 9 p.m. power had been restored to all but 30 customers in the area of South Allante Place and Chase Street.

More rain was forecast overnight, but Wednesday is expected to be dry in the Treasure Valley. Another system is expected to bring more rain Thursday, Colin said.
