About pollen in Killeen
Pollen is running high in Killeen today, with tree and weed pollen both likely to cause noticeable symptoms for sensitive individuals. Grass pollen is also present at a moderate level, adding to the overall load. Anyone prone to seasonal allergies may want to take extra precautions today, particularly if spending extended time outdoors. Looking ahead, tree and weed pollen are expected to remain high for the next couple of days before easing into a more moderate range by midweek. Grass pollen should follow a similar pattern, gradually tapering off. This lines up with the seasonal norm for late September in Central Texas, as late-blooming weeds like ragweed remain active while common local trees such as cedar elm and mountain cedar begin their seasonal wind-down.
