About pollen in Dayton
Grass pollen is the main player in Dayton today, sitting at a Low level (2 on the Universal Pollen Index), and it's also what's keeping the overall reading at Low. The near-term forecast holds steady at that same Low level for the next few days before easing slightly toward the end of the period. This fits the season, as late spring into early summer is typically when grass pollen does most of its work, while the tree pollen that dominates earlier in spring has largely faded. Tree and weed data aren't available right now, so today's picture leans entirely on grass figures. Ragweed, the big weed-season driver, generally doesn't ramp up until later in the summer and into fall.
