Forecasting For Phoenix

Should get a break, over the next week, with thunderstorms.

Lots of lower-level moisture from the south, particularly with Hurricane Emilia, spinning away off the southern Baja coast, acting to pump moisture north.

Upper level winds from the NE, from the Rim. The different wind directions means a considerable amount of shear - more than normal - which can, under some circumstances, promote storms.

It seems promising. What can go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong, go wrong?
