ST. LOUIS (KSDK) – The heat picks up Tuesday, and it brings a 2014 milestone.

The orange label means air means members of sensitive groups – such as people with lung disease or asthma – could be affected, according to the U.S. Environmental Protection Agency. The general public is unlikely to be affected.

Tuesday's heat index should be around 100 this afternoon, and there's a chance for storms Tuesday night and Wednesday, according to NewsChannel 5 meteorologist Scott Connell.

Cooler and drier air is expected Thursday into Friday.
