FORT WAYNE, Ind. (WFFT) — We're in the midst of spring allergy season across northeast Indiana and northwest Ohio.
Tree pollen is at high levels through May, but grass pollen levels start to rise throughout the month.

Have you noticed how weather plays a role in pollen distribution?
After rain, pollen levels drop.
Moisture weighs down the pollen, preventing it from traveling.
Rain also washes pollen out of the environment, but a heavy rain can make things worse.
That's because the intense rain can release a higher number of smaller pollen particles into the air, according to allergists.
Rainy falls and winters can also increase pollen level for the following spring.
When we're in a dry stretch, pollen levels drop because plants typically grow slower.
Drought conditions make it harder for plants to grow.
However, if you're allergic to mold, the dry conditions actually make things worse.
That's because mold spores may lift from the soil during dry and hot weather.
Windy conditions also can raise pollen levels.
The wind helps stir up dust, mold and pollen, activating allergies.
Temperatures also play a big role in allergy season.
A mild winter can lead to an early start to allergy season because trees and plants can start pollinating earlier.
Sudden drops in temperature can freeze tree pollen production, according to infoplease.com.
Frequent large temperature variation can also make one's allergen sensitivity.
Even though rainy conditions started the week in northeast Indiana and northwest Ohio, tree pollen levels will remain high through the end of the week.
Grass pollen levels will begin climbing on Thursday.
