Discussion
The quantity of pollen grains in the air for Sunday will be increasing over today's levels in the moderate range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and the lower dewpoint.
Allergy Facts
Although pollen grains can often travel extreme distances from the plants that shed them, grass pollen tends to stay near its source. One study demonstrated that 99% of grass pollen remains within a mile of the plants that shed it. This suggests that the cause of grass pollen allergies is probably right outside your door -- perhaps the front lawn or some roadside grasses.
