Slight chance of thunderstorms tonight and Friday - High of 110

PHOENIX -- Summer storms may be on tap early Friday in the Phoenix area.

The National Weather Service predicts a slight chance of showers and thunderstorms after midnight Thursday into Friday.

Gusty winds and lightning are the primary threats from any storms that develop.

Forecasters say there's an increasing chance of showers and thunderstorms through the weekend with the greatest threat late Saturday into Sunday.

Meanwhile, there's a slight chance of showers and thunderstorms Thursday afternoon in east-central Arizona including Gila County.

Lightning and gusty winds could develop.

Weekend brings chance of monsoon storms

This upcoming weekend could be the first time this year Arizona sees a significant monsoon storm.

The National Weather Service is predicting a 30 percent chance of showers and thunderstorms in the Phoenix area on Saturday. Activity also is expected in higher elevations and eastern Arizona.

The monsoon starts June 15, although no significant storms or rainfall have occurred. The season lasts until Sept. 30.

Monsoon storms can produce strong winds and blowing dust that make driving difficult, and can bring dangerous lighting and flash-flooding.

Last year's monsoon produced below-normal rainfall, and as National Weather Service meteorologist Valerie Meyers puts it, was "pretty much what we call a dude."

Meyers says this season is expected to be normal.
