About pollen in Lee's Summit
Weed pollen is the main story in Lee's Summit today, and levels are high enough that sensitive individuals will likely notice symptoms through much of the day. If you tend to react to ragweed or similar weeds, it may be worth limiting time outdoors during peak afternoon hours and keeping windows closed when possible. Looking ahead, weed pollen is expected to hold steady at a high level for the next several days before easing slightly toward the end of the five-day stretch. This tracks with the typical pattern for early October, when ragweed and other late-season weeds are at their strongest before cooler weather sets in. Tree pollen, which comes from species like oak, maple, and elm here in the region, is not a concern at this time of year and will remain quiet until spring.
