A string of thunderstorms moved northeast Friday afternoon through the Las Vegas Valley, causing flash flood warnings and dropping high temperatures 20 degrees.
The clouds causing the heaviest rainfall eventually broke apart and moved east, decreasing the chance of flooding.
“Nowhere around the valley got more than an inch,” National Weather Service meteorologist Chris Stumpf said.
The department’s rainfall-measuring locations throughout the valley reported 0.47 inches at Anthem Detention Basin, 0.16 inches in Henderson, 0.09 inches at Nellis Air Force Base, 0.06 inches at McCarran International Airport and 0.02 inches at the North Las Vegas Airport.
The weather service received no reports of flooding in Clark County, Stumpf said.
The weather service issued two flash flood warnings Friday afternoon, first for south central Clark County lasting until 5:30 p.m. and then for central Clark County until 6:30 p.m. The central county warning was extended until 7:30 p.m.
Because of the chance of additional rainfall today , Clark County remains under a flash flood watch, a step down from a warning, until midnight.
The thunderstorms broke a stretch of triple-digit-temperature days in the area. Friday’s high temperature reached 86 degrees, a dramatic difference from Thursday’s high of 106 and highs of 113 and 114 earlier in the week. Relatively cooler temperatures are expected to last until drier air moves back into the area on Wednesday.
Weekend forecasts predict a high of 90 degrees and a 60 percent chance of rain today . A high of 97 degrees and a 30 percent chance of rain is predicted for Sunday.
