Expect another gorgeous day Friday in the Austin, with weather very similar to Thursday’s.

Temperatures will be in the 60s until about 10 a.m., when the city will begin to rapidly warm up, the National Weather Service said. We’re expected to reach a high of 84 degrees in the late afternoon.

It’s not all good news today: Texas has declared Friday an Ozone Action Day for the Austin metro area, which includes Travis, Williamson, Hays and Bastrop counties. That means those particularly sensitive to ground-level ozone, such as elderly people, those with asthma or other lung diseases and young children, should minimize the amount of time they spend outdoors.

Ozone is a smog ingredient produced by a combination of sunlight and pollutants, such as those from gas-powered engines. People can take steps to mitigate ozone by avoiding the use of gas-powered equipment, using public buses and trains, combining errands to avoid multiple car trips, and not idling a vehicle’s gas engine.

Looking forward, Saturday’s weather is expected to be a little cloudier and a little warmer, with a low of 66 degrees and a high of 84, the National Weather Service said.

Plan for muggy weather on for Mother’s Day on Sunday. There’s just a slim chance — 20 percent — of thunderstorms throughout the day, so plan for the possibility of scattered rain.
