BUT LAS VEGAS HAD A 70 F DEWPOINT!!!! PHOENIXS DEWPOINT WAS 64 F . WHAT IS GOING ON??? WHERE IS ALL THE DRY DESERT AIR GOING????
Gees, it is much drier in Houston than in Sahara Desert and that place is very dry. The Southwest is wet because it is monsoon season. Every night, I see large areas of thunderstorms over northwestern Mexico at this time.wxman57 wrote:It appears that the desert has shifted east - to Houston.

WHAT IS THE ACTUAL MECHANISM,,THAT IS PUSHING THE HUMID AIR INTO THE DESERTS? IS IT A LOW ALTITUDE WIND SHIFT? THE MOISTURE HAS TO BE COMING FROM SOMEWHERE. THIS IS RIDICULOUS!!!
