About pollen in Tri-Cities
Grass pollen is the main driver in Tri-Cities today, sitting at a moderate level (3) and holding the overall index at moderate. Expect this to persist over the next couple of days before easing slightly, with the forecast dropping to a level 2 for the latter part of the window. The timing fits the season, as grasses typically dominate through late spring and early summer in this region. Tree pollen, which generally peaks earlier in spring, is not reflected in today's data, and weed sources like ragweed usually don't ramp up until later in summer. For now, grass remains the pollen to watch.
