Heat, humidity build cells that drop light rain on the valley
Storm cells are moving briskly across the Las Vegas Valley early Sunday evening.
Heat and humidity helped the storms develop late in the afternoon.
“They should clear out pretty quick and it should be clear after that,” National Weather Service meteorologist Jenn Varian said.
The cells moving southwest to northeast dropped light rain with some gauges mainly across the southern half of the valley showing less than .05 of an inch.
The coming week should be dry, according to the weather service.
With one final day of storm activity, watch out for a few stronger storms today – especially across Lincoln county an eastern Clark County. Strong winds and hail will be possible in these areas as our weather system departs the area. #nvwx #azwx pic.twitter.com/zZoNsEd8fV

The 2.55" of monsoon precipitation measured at the airport doesn't always tell the full story for the Las Vegas Valley.
Monsoon rainfall often has a lot of spatial variation, so here are the monsoon totals across the valley!
