Pollen Index: 9.3 Pollen Level: medium-high Predominant Pollen: Ragweed, Elm and Chenopods. Pollen concentrations for Thursday will be falling in the low range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, rising humidity and heavy rains in the afternoon and evening which tend to wash pollen out of the air. The lower pollen levels are significant and should help allergy sufferers to cope tomorrow.
A widespread heavy rain event is taking shape across portions of the Southern and Central Plains into the Corn Belt, bringing an increasing risk of flash flooding through early Thursday.
