Discussion:

Today's pollen rating is 28 (MODERATE), all TREES: 43% cedar, 43% elm and 14% maple. Lower than expected winds helped to keep tree pollen levels in the MODERATE range today. Winds will be somewhat higher for the next three days allowing tree pollen levels to increase to the lower end of the HIGH range. No precipitation is expected through Saturday. Overnight low temperatures will be in the upper 30’s to low 40’s with daytime highs in the upper 60’s and low 70’s. Grass and Weed pollen are typically ABSENT at this time of year. (Russ)
