High pressure returns this week, bringing with it hotter weather and a slightly decreased chance of rain.

Forecasters say temperatures in Tucson Wednesday could be as high as 108. Phoenix is forecast to be around 112, while Gila Bend and Yuma could reach 116. While not unusual for August, the heating trend will send temperatures well above average, which should be 97 for August 8 in Tucson.

The National Weather Service has issued excessive heat warnings through Wednesday evening for Phoenix, Casa Grande, Gila Bend and Yuma. Residents of those areas are advised to limit outdoor activity and drink lots of water.

Rain remains in the forecast through the week, especially for Wednesday night.

J. J. Brost with the National Weather Service in Tucson says August could end up being cooler and wetter than normal, this week notwithstanding.
