The warm, dry weather over the weekend brought a lot of you outside this weekend...and you may be paying for it today. The spring allergy season is in full swing right now. With the warmer weather, the tree pollen has gone through the roof in recent days, and pollen counts are the highest they have been all spring.
Pollen is typically measured using a device called a 'rotorod'. The rotorod is a group of clear rods coated with a silicone grease that are exposed to the air at certain intervals over a 24 hour period. Pollen grains are collected as they stick to the grease coated rods. The rods are then examined under a microscope where the individual grains of pollen are counted and indentified. Based on the counts, a concentration of pollen in the air is calculated and given as a number of grains per cubic meter of air.
The latest pollen count in Huntsville was taken last Tuesday...there were 150 grains per cubic meter then, but that was before the warm up we had this weekend. In Atlanta today the pollen count had climbed to more than 2,000 and we're likely seeing similar numbers for north Alabama.
With more warm and dry weather expected through midweek, don't expect any relief. Pollen levels will stay in the extreme range through Wednesday.
Shower and storms moving on Thursday will bring some temporary relief, but the pollen levels will skyrocket again as dry weather returns this weekend.
