About pollen in Columbia
Weed pollen is the main driver of today's conditions in Columbia, running high enough to cause noticeable symptoms for those who are sensitive. Grass is contributing at a moderate level as well, so combined exposure could feel like more than a typical day. Tree pollen, by contrast, is low and not expected to be a significant factor right now. Looking ahead, weed pollen should ease slightly over the next several days but remain elevated, while grass levels hold fairly steady before tapering toward the end of the period. Tree pollen is likely to stay low throughout. This pattern fits the season: late September is prime time for ragweed and other fall weeds, which typically overshadow the oaks, pines, and other trees that are far more active in springtime. Anyone bothered by weed allergies should expect this to be an active stretch for a while longer.
