Discussion
The quantity of pollen grains in the air for Sunday will remain relatively stable in the moderate range. This is a result of stable temperatures. No change doesn't mean no pollen, it just means that pollen producing plants are delivering pollen at a steady pace.
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.
