Monday's high is forecast near 83.

Storm Chances Monday

Showers and thunderstorms are possible Monday afternoon and evening.

The National Weather Service in Las Vegas says tropical moisture and a passing storm system will raise the risk of heavy rain across southern Nevada. The greatest flash-flood concern is farther east and toward the Colorado River Valley.

Storm Chances Continue Tuesday

Storms may remain possible Monday evening.

Storm chances continue Tuesday, with a high of 82 degrees.

Drier Weather By Weekend

Conditions turn drier, with dry weather forecast Friday through Sunday.

That makes Monday and Tuesday the main weather-planning headache: Keep outdoor plans flexible and never drive through floodwater if a storm cell moves overhead. By midweek, the forecast settles into the familiar desert routine of bright skies and steadily warmer afternoons.
