For Attorneys
Storm evidence cited from
the original government record.
HailScore storm-history reports cite NOAA Storm Events database identifiers, NEXRAD radar station codes, and NWS warning polygon IDs for every event. Defense counsel can verify every fact against the public record — the evidentiary footing that proprietary “storm severity scores” do not survive on cross-examination.
Plaintiff and defense counsel. Property damage, bad-faith insurance disputes, hail-related litigation.

§I · The exhibit
What goes into the file.
Every HailScore storm-history report is a single-PDF attachment. It opens with the property identifier, the loss-date window you specified, and a one-line summary of confirmed hail occurrences within that window.
The body of the report lists each event as a discrete row: date, time (UTC and local), estimated hail size, distance from the subject property, and the government-record source identifier for that event.
The footer of every page contains the data-provenance statement and a generated-on timestamp. The PDF is unmodified between generation and delivery; the hash is recorded on our end for chain-of-custody purposes.

§II · Data sources
Five government sources. One report.
Each fact in a HailScore report originates with one of the public-record sources below. The citation format shown is what appears next to the event in the PDF.
| Source | What it provides | Citation format | Latency |
|---|---|---|---|
| NOAA Storm Events Database | Confirmed hail occurrence, location, magnitude, narrative | Episode ID + Event ID (e.g. 174532-1056981) | 60–90 days post-event |
| NEXRAD Level-II / SWDI MESH | Radar-derived maximum estimated hail size, sub-county resolution | Station code + UTC timestamp (e.g. KFTG 2024-06-19 21:47Z) | Continuous, historical 2015–today |
| SPC Local Storm Reports | Ground-truth reports from spotters and law enforcement | LSR identifier + reporting office | Hours (preliminary), days (final) |
| NWS Active Alerts API | Severe Thunderstorm / Hail Warning polygon coordinates, issuance time | VTEC string + polygon ID | Real-time |
| NCEP MRMS (Multi-Radar / Multi-Sensor) | Operational hail-size estimates, 2-minute resolution | MRMS product code + UTC timestamp | Hours after the storm |
Full source schemas and ingestion methodology are documented in the public methodology white paper. Disclosable to opposing counsel.
§III · FRE 702 & Daubert
The score is context.
The cited record is the evidence.
“A witness who is qualified as an expert … may testify in the form of an opinion or otherwise if … the testimony is based on sufficient facts or data; the testimony is the product of reliable principles and methods; and the expert has reliably applied the principles and methods to the facts of the case.”
— Fed. R. Evid. 702
Federal courts have repeatedly excluded expert testimony built on proprietary “storm severity” scores when the underlying methodology cannot be independently tested or verified. The challenge is structural: a score that nobody outside the vendor can reconstruct fails the second and third prongs of Rule 702.
HailScore reports are designed to sidestep that failure mode. Every event in a report names a specific public-record source — NOAA Storm Events narrative number, NEXRAD radar station code with UTC timestamp, NWS warning polygon ID, SPC Local Storm Report identifier. Opposing counsel, your expert, or the trier of fact can pull the originals.
The HailScore number is contextual — useful for the homeowner. The cited records are what go in the exhibit list.
