Predominant Pollen: Ragweed, Chenopods and Nettle

Outlook

The amount of pollen in the air for Sunday will be greater than today's levels in the high range. This results in part from drier air. If you have these allergies, tomorrow will likely be more difficult outdoors.

Today

The quantity of pollen grains in the air for Saturday will be increasing over today's levels in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and windy conditions.

Allergy Fact

The great aerobiological pioneer Durham estimated that 415 pounds of ragweed pollen fell per square mile in Milwaukee, Wisconsin, during the early 1930s. This was likely a significant underestimate.
