If your allergies have been bothering you more than usual in recent days, mold spores could be to blame.
The latest readings for the Philadelphia area show that pollen is nearly nonexistent and ragweed is low or very low.
Mold spore counts, however, were very high Tuesday, after having gone into the extreme zone Monday.
“We are seeing extreme levels of outdoor mold spores due to warm temperatures and high humidity,” Dvorin said Monday. “It is unusual for October to be seeing these longer periods of elevation in temperatures.”
