Rain can temporarily decrease pollen counts in the air, but only if its a heavy enough downfall, light rain may not change pollen counts by very much. Following the rain, the humidity and warmer weather can actually increase pollen counts. Other aero-allergens like mold can increase and cause more symptoms too. So, it can be good and bad.
And then there are thunderstorms. Certain wind patterns called updrafts can occur and can these can worsen allergies and asthma due to increases in mold spore counts and a decrease in the size of grass pollen particles which can affect the respiratory tract more easily.

If you have allergies or asthma, talk to your allergist about tips you can follow to prevent your allergies or asthma from flaring!
