Tucson monsoon

Monsoon clouds gather over the cactus forest in the Saguaro National Park West, Wednesday, August 10, 2016.

One more day of triple-digit heat, before we get a brief reprieve from the heat in the form of rainfall and much cooler temperatures.

A few thunderstorms with gusty winds are possible today, but rain chances increase tomorrow with the best chances for rainfall in Tucson occurring Friday night into Saturday morning.

Heavy rain is possible with flash flooding in certain areas.
