Sneeze of the day: Pollen levels high in Chicago area

Pollen counts have been consistently high for the past month, but are finally starting to come down.

Yes, but: Fall allergy season typically tapers when frost arrives in late October or early November.

The big picture: Worsening allergy seasons are a concern nationwide. NOAA researchers are developing a new pollen forecasting model, the first of its kind for a federal agency.
