Discussion
The pollen levels for Sunday will be falling in the moderate range. This change results in part from rising humidity, relatively calmer winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. This will improve your outlook if you have allergies and enjoy the out of doors.
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.
