How often severe weather threatened a ZIP code in the last 5 years: hail and thunderstorms, wind, freezes, heat and floods.

Questions

Where does the data come from?

National Weather Service warnings that covered the center of the ZIP code, from the Iowa Environmental Mesonet archive of NWS products.

Is it free?

Yes. The summary is free for everyone; the full year-by-year report asks only for your email.

Why warnings and not damage?

Warnings are the official, consistent record of when severe weather threatened an area. They do not say how much damage happened at a given address.
