Mostly rain-free weekend ahead

"Good" AQI is 0 to 50. Air quality is considered satisfactory, and air pollution poses little or no risk.

"Moderate" AQI is 51 to 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.

"Unhealthy for Sensitive Groups" AQI is 101 to 150. Although the general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

"Unhealthy" AQI is 151 to 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.

"Very Unhealthy" is AQI is 201 to 300. This would trigger a health alert signifying that everyone may experience more serious health effects.

"Hazardous" AQI is greater than 300. This would trigger health warnings of emergency conditions. The entire population is more likely to be affected.

Breathe. The weekend will be sunny and mostly rain-free.

“Our rain chances go up, but only slightly as we head into Sunday,” Channel 2 Action News meteorologist Brad Nitz said.

The Atlanta weather forecast calls for a 20 percent chance of rain on Sunday and Monday.

In the meantime, the metro area will stay completely dry.

Temperatures will reach 71 degrees by 8 a.m. 86 degrees by noon and 93 degrees by 4 p.m. Saturday.

They were 87 degrees in Atlanta, 82 degrees in Blairsville and 87 degrees in Griffin just before 1 p.m. Friday.

Temps are expected to increase to a high of 93 degrees by 4 p.m. in Atlanta.

And with the heat, smog could potentially pose a problem for some.

A code orange smog alert was issued Friday for metro Atlanta. That means air quality could put sensitive groups at risk as temperatures start to push toward the lower 90s this afternoon.

"Watch for symptoms such as coughing or shortness of breath," according to a post from the Environmental Protection Agency.
