It's very tempting on these cooler fall days to drop the top on your convertible but if your allergic to elm or ragweed pollen this may not be a good idea. Even with the Summer drought the recent rains in the Brazos river valley have pushed up a good number of weeds recently. This is the source area for most of our ragweed pollen. The dry fall air blowing from the North and West brings and end to summer but the start of fall allergies.
A cool front expected on Tuesday may bring in a good number of these allergens into the region. Local elm tree pollen levels are exploding with over two thousand grains per cubic meter of air measured over a 24hr period. Ragweed has also risen into the triple digits for the first time this year but levels are expected to climb even more in the coming weeks as ragweed pollen begins to peak. The local area could see pollen counts for ragweed climb into the thousands, since each ragweed plant can produce up to one million pollen grains.
