About pollen in Chicago
Grass pollen is the main driver in Chicago today, sitting at a Low level on the Universal Pollen Index, which keeps the overall reading at Low as well. The forecast points to steady conditions over the next several days, with grass holding at this Low mark before easing slightly toward the end of the period. This fits the season, as late spring into early summer is typically when grass pollen is most active across the region. Tree pollen, which dominates earlier in spring, is not reported in today's data, and weed pollen tends to stay quiet until ragweed picks up later in the summer and fall. Overall, expect a generally light, stable stretch for now.
