Las Vegas has a 30 percent chance of storms Sunday night. South winds between 20 and 30 mph are forecast to pick up in the afternoon and evening.

Temperatures will see a drop of 5 to 10 degrees compared to the recording breaking heat on Saturday, with highs in the 90s — which are expected to continue into the week.

Boaters on Lake Mead should take caution. Winds of 20 to 25 mph could produce waves up to 3 feet Sunday afternoon, with scattered overnight storms possible.
