Discussion:
Today’s GRASS pollen rating is 17 (LOW). Today’s WEED pollen rating is 7 (LOW). Today's TREE pollen rating is 1 (LOW): 100 % pine. Yesterday’s rain helped to wash down the pollen from the air. There is a 60% chance for thunderstorms tonight and a 20% chance on Thursday. Friday will be mostly clear and Saturday mostly sunny. Daytime high temperatures will be in the low 80s to low 90s through Saturday. Overnight lows will be in the mid 60s.
