We've gone so over the top on weather fearcasting. Just look out the window if you want to know what the weather is. Save the "the world is ending" messages for truly life-threatening, property-damaging weather (and no, temperature alone doesn't qualify---it's easy to know it's cold or hot by just stepping outside).

Timely. I’m about to turn off severe weather alerts from my local city because they insist on spamming - multiple times per day - cold weather alerts.

And they start at pretty ridiculous temperatures in the double digits. The only way those would be dangerous to you is if you were homeless and lacked any form of winter clothing, at which point you either already know or are too far mentally gone for a text alert to help you.
