Just How Rainy Has It Been In The Las Vegas Valley?

From the Las Vegas Sun: Las Vegas and the region should catch a break this weekend from a record-setting monsoon season, but not before more rain douses the valley this evening.
The National Weather Service issued a flood advisory as a band of moderate to heavy rain slowly traveled southeast through the region.
Rainfall totals were highest about 7 p.m. on the east edge of the valley near Wetlands Park, peaking at about 1/2 inch. One car was stuck in 2 to 3 feet of water on a flooded entrance ramp to Interstate 95 from Tropicana Avenue about 6:20 p.m., forecaster Mike Kennedy said....
Chris Stachelski, a National Weather Service meteorologist, said today marked the 20th consecutive day in which at least a trace of rain had been recorded somewhere in the Las Vegas Valley or its immediate surrounding area.
That nearly three-week stretch of rainy days far exceeds the previous record of 12 straight days of rain, in both 1967 and 1998.
“This weekend will be first fully dry weekend since Aug. 10 and 11, which is pretty remarkable,” Stachelski said.  http://www.lasvegassun.com/news/2013/sep/11/consecutive-rainy-days-20-and-counting-and-around-/
With the exception of a couple of weeks in late June, this summer has been normal, if not below normal, temperature wise.
