It's been a very unusual and wild weather day in the Las Vegas Valley today. The combination of plentiful monsoon moisture and an upper-level disturbance moving through south-central California has brought a deluge of rain, causing flash flooding.
Here are a few of the interesting statistics.
The normal high temperature is 101 today with a normal low of 79. The highest temperature today was 83, but that was before dawn. For much of the daylight hours, temperatures have been in the low 70s, 6 to 8 degrees below the normal low.
As of 2 p.m. PT, McCarran Airport has had 1.60 inches of rain, Henderson has had 2.14 inches, and Boulder City came in with 1.26 inches. It was still raining as I write this. To put this into perspective for you, the normal YEARLY rainfall is 4.20 inches. Before today, McCarran had 0.63 of an inch this month; so in the month of August, there has been more than half of the normal yearly rainfall.
Drier air will move into the Las Vegas Valley tomorrow as the richest monsoon moisture gets pushed to the east.
This is setting the stage for some places to be within reach of their all-time driest year on record.
