Why Does The Atmospheric Pressure Rise During Strong Thunderstorms?

[Coach McGuirk]

I see this all the time when there is a strong thunderstorm passing over me. You'd expect it to drop (like a hurricane or a tornado passing by) but it always rises.

My only guess is that it has to do something with the high pressure of the cold front.

Gravity wave?

C'mon, man. Blow really on to your hand. What happens?

Rain cooled air at the surface.

So you're saying downdrafts create high pressure. Makes sense.

It is a gravity wave with a thunderstorm.

Can I please have a Met who knows tell me if I'm right or wrong.

for some reason i laughed really hard at this

meso high

evaporational cooling ...low level thickness decreases, surface pressure rises

Short phrases explain everything!

Also, cold air is denser than warm air.
