About pollen in North Peoria
Weed pollen is running high in North Peoria today, and it is the main driver of allergy discomfort right now. If you are sensitive to ragweed or similar late-season weeds, expect symptoms to be fairly noticeable, particularly during outdoor activity in the afternoon. Over the next couple of days, weed pollen should hold at a similarly high level before easing toward midweek and then ticking back up slightly after that. This pattern fits the season well, since late September is peak time for ragweed and other weeds across the Midwest, well after the spring tree pollen from oaks and maples and the early-summer grass pollen have faded. Expect weeds to remain the main source of irritation until the first hard frost arrives.

- When driving the car, close your windows and turn the air conditioning system to recirculation mode.
