Day of threatening Las Vegas storms ends as sunset nears
Storms that popped up in mostly higher terrain areas around the Las Vegas area for several hours Wednesday have come to an abrupt end.
In the last warning, Pahrump and Sandy Valley were under a flash flood warning until 8 p.m. But the rather strong cell along the Nevada-California state line disappeared about 6 p.m.
The National Weather Service said heavy rain, flash flooding, winds of 40 mph or more and frequent lightning were possible.
“We had a lot of activity through the whole day from the Spring Mountains to Searchlight,” meteorologist Ashley Nickerson said. “With sunset coming, there’s not a lot of energy for storms to feed on.”

As of 3 p.m., .67 of an inch had fallen in 90 minutes at a gauge at Blue Diamond Ridge South, basically the second line of mountain ridges west of Summerlin.
And, .28 of an inch had fallen near Mesa Ridge, the first line of mountain tops. A gauge just south of Calico Basin has received .43 of an inch in the past three hours.
The rain must be sort of the “third time is a charm” since the valley saw heavy clouds Monday and Tuesday, but did not receive much if any precipitation.
The Wednesday forecast listed rain as a 30 percent chance in the valley, with a high of 96 and low of 82.
Showers earlier today dropped about .20 inches along a few parts of the 215 Beltway in Henderson.
Hikers and campers were warned to avoid streams and washes and to know where they are relative to these areas as they can become deadly during heavy rain.

The agency said “deep moisture will fuel thunderstorms capable of producing heavy rainfall.”
The pattern of monsoonal moisture is not expected to end anytime soon. Chances for rain remain in the valley’s forecast for the rest of the week.
