The Loyola Medicine Allergy Count reports pollen counts each weekday morning in Melrose Park.

On Tuesday, the area recorded a "very high" count of 82,121, breaking the 2014 record. On August 20, 2014, the area recorded 82,000.

On Wednesday, Loyola reported the mold count was still "high."

The mold count measurement is based on the number of grains of pollen or mold spores in a cubic meter of the air, according to American Academy of Allergy Asthma and Immunology.

Allergy season commonly runs from March through the first hard freeze in October.
