 Winds of up to 55 miles an hour are expected, along with blowing dust and heavy rains. Temperatures will be rising this week, possibly hitting 115. But Phoenix National Weather Service meteorologist Gabriel Lajero says we start the week tonight with a decent chance of a monsoon storm. Today, Sunday, we'll have the best chances, especially later this evening. We expect a cluster of thunderstorms to develop near the Tucson area, and that's going to be moving forward.
