More about our Reports
A StrikeMaps Property Weather Report is a summary of the public weather record for a specific address on a specific day. It pulls together NOAA SPC storm reports, the day’s SPC outlook, archived NEXRAD radar, and Mapbox satellite imagery into a printable PDF. Here’s what’s in one.
What’s in a Property Weather Report
A walkthrough of every section of a real Day Report. Names and address are redacted, but every other element is exactly what gets generated.

Storm character
Severe storms move as systems, sometimes spanning dozens of miles. A report on a single address has to look beyond that address to understand the storm’s character — whether it was a discrete supercell, a squall line, or a multicell cluster. We pull reports from three nested radii, and each one answers a different question.
- 3 mi·Single cell
Within 3 miles, a single storm cell is most likely to have produced consistent conditions across the area. Tighter and SPC reports thin out; wider and you start mixing in unrelated parts of the storm.
- 5 mi·Multi-year coverage
SPC reports are sparse — especially for older events. Five miles is wide enough that an address typically has some history over a multi-year window, but tight enough that the reports still describe weather near it.
- 10 mi·Storm system
Severe storms travel as systems that span dozens of miles. Ten miles is wide enough to read the storm's shape and mode — supercell, squall line, multicell — without pulling in activity from an unrelated system.
A real storm field across DFW — each pin is one hail, wind, or tornado report from the same day.
Where the data comes from
Every section of a report is built from publicly-available data published by NOAA, the National Weather Service, and partner archives. We don’t generate weather data — we organize it.
NOAA Storm Prediction Center
Every storm report in a Day Report comes directly from the NOAA Storm Prediction Center's daily storm-report archive. SPC reports are preliminary observations and are sometimes revised during quality-control review.
National Weather Service
The storm direction and speed in the Storm Summary are derived from archived NWS warnings issued during the event — the same operational products meteorologists used in real time.
Iowa Environmental Mesonet — NEXRAD
The radar snapshot in every Day Report is composite reflectivity from IEM's NEXRAD RIDGE archive, mirroring NOAA's national NEXRAD network. The frame is aligned to the storm window for the selected date.
Mapbox & OpenStreetMap
The satellite frame, base cartography, and address geocoding are from Mapbox. Road, boundary, and place data is contributed by the OpenStreetMap community.
