Daytime high temperatures will continue to increase through Wednesday.

SYNOPSIS FROM THE PHOENIX OFFICE
Extreme temperatures continue today. In fact, most desert locations will be even hotter than Monday leading to record or near record readings. Over higher terrain areas of Arizona, scattered thunderstorms will produce very little rain but strong winds. Those winds are expected to spread to the central Arizona deserts by this evening causing areas of blowing dust. Anticipate a subtle decrease in temperatures Wednesday and Thursday with little change Friday through Sunday. However, very hot conditions will remain in place.
