sprites, I remember those California Ads
"Now southern California is entering it's 8th year drought, please save water"
But it really wasn't warm at all, it was just cold and dry for many winters.
I think what azdustman is really worried about is residual dryness, that is even though the upper levels of the atmospheres has water in the forecast, because it has been so dry for so long, below the surface of the atmosphere near the city of Phoenix, the air acts like a giant vacuum and sucks up all the available moisture and draws it right back up in the air again (evaporates before it touches the ground) I forgot what that's called. Verga? )and moves elsewhere.
If you look at the satellite archives you can actually see that each time a storm tries to make it to Arizona it falls apart and dies. But the storm somehow manages to magically reappear again near Texas. That's because the RH has to be near 100% to get the full effect.
It's going to take a torrential downpour to get that city back on track, but one big storm like this one could do it.
I have a friend from Phoenix who says it's not only dry, but the air quality is just awful for winter.
