KANSAS CITY, Mo. — The pollen and mold counts are lower today which is a relief for people with allergies. Mid-season genera such as Maple are starting to dominate the count. We also periodically see grass pollen, though most of that comes from further south where the season has progressed more than here. Long-distance transport of pollen can be an issue at times. An example is Mountain cedar which comes from central Texas during December in plumes. That is their version of ragweed season.
