The Monsoon Season...
Summer in the Southwest is also the Monsoon Season there. Something about a subtropical ridge from Mexico and a thermal low from Bangladesh causes this annual weather pattern normally associated with the tropics (during our winter months). The thunderstorms hang out during the early part of the day over the Sandia Mountains shadowing Albuquerque. Late in the afternoon and evening, the clouds turn dark, move over the city, and it rains like hell, sometimes for just a few minutes, sometimes the better part of an hour. Then, the next morning, one wakes up with a typical New Mexico summer sky: deep azure blue, with huge, billowing, white Simpsons clouds. Then the pattern begins all over again.
Just one of the many enigmas that is New Mexico. It is much more than the hot, arrid, desert southwest most people perceive.
