LMAO, they test the sirens once a month on Wednesday, for anyone unfamiliar.
(Edited, I live real close to one, but I don't really pay attention to the day or frequency. Tons of trains around too, you learn to drown it out.)
Midwesterner that gets noon on Friday tests here. I got the joke tho.
Ours is Mondays!
But what if a tornado actually appears at that time?
The image says what happens. It can't hurt you, it's against the rules.
They cancel it if the weather isn’t good, just in case they need it for real.
They'll likely run a different signal than the normal test. If, for example, they normally test in "alert" (steady) then they might use the "attack" (wavering up and down) signal instead.
Then the Tornado Guards will shoo it away.
Then they nuke the tornado
you would know, it's almost always done during clear weather.
It runs for maybe a minute at 1pm. If it goes off before or after, it's not a test.
Like in 2017 in Mexico when the earthquake happened like two hours after their yearly earthquake drill. People figured it out pretty quickly, but I've never been in a tornado so I don't know if it'd be as easy to tell as an earthquake.
What if it's just a very thorough drill?
Depends on the region. Some places will test it on noon on Sundays. The place I'm currently at will test it once a month on Wednesday at 11 am.
Ours get tested on Saturday
I lived in a small farm town on the Mississippi river in the Midwest for years. Their siren would literally go off at 6pm every, single, day. (Albeit very briefly) Something about letting people outside know it was time to head home for supper.

1pm local time on the first Wednesday of the month in my state.
