Forensic Weather Report by Address & Date of Loss
A source-cited reconstruction of what the weather did at a specific property on a specific date — radar, soundings, storm reports, and NWS forecast guidance, scored by roof-relevant hazard. Built from primary government data, in minutes.
What a forensic weather report answers
In property claims, the decisive questions are meteorological: what actually happened at this address, on this date? How strong were the winds? Was there hail — and how large? A forensic weather report answers them from the same primary data a testifying meteorologist works from, and links every finding back to its official source so the evidence trail is auditable.
What’s in a report
The geocoded address and parcel, with the nearest NEXRAD radar and its distance.
Every recorded storm event near the property in the window, each linked to its official source.
Wind, hail, and tornado evaluated separately, each scored by data strength (tiered).
NEXRAD Level II reflectivity and radial velocity, georeferenced to the address at the sampled beam height.
The nearest observed sounding (skew-T) with CAPE, shear, and freezing level — the pre-storm setup.
NWS Local Storm Reports, the NWS Area Forecast Discussion issued before the event, and NOAA NCEI Storm Events records.
Primary data sources
- NOAA NEXRAD Level II radar — reflectivity and radial velocity
- NWS Local Storm Reports & warnings (Iowa Environmental Mesonet)
- NOAA NCEI Storm Events Database
- NWS Area Forecast Discussions and Terminal Aerodrome Forecasts
- Rawinsonde (RAOB) soundings — University of Wyoming archive + MetPy indices
- US Census Bureau geocoder and Regrid parcel records
Who it’s for
Evaluate a date-of-loss claim against what the weather actually did, with source-cited evidence.
A defensible, methodology-transparent record for property-damage matters, with meteorologist certification available.
Independent, primary-source documentation of the storm environment at a specific property.
Confirm a storm hit the address before investing in an inspection or claim.
A note on what these reports claim
Stormview frames its conclusions as plausibility and consistency with the observed conditions — not confirmation that damage occurred at the structure. Radar samples aloft, not at roof level, and radial velocity is along-beam motion, not true surface wind. Conclusions are produced UNVERIFIED until a credentialed meteorologist reviews and certifies them. Roof-damage causation and extent are handed off to a licensed contractor or forensic engineer; legal evaluation to counsel.
Frequently asked questions
What is a forensic weather report?
A forensic weather report reconstructs what the weather did at a specific property on a specific date using primary government data — NEXRAD radar, NWS storm reports and warnings, soundings, and NCEI records — with each finding linked to its official source.
What data sources does a Stormview report use?
NOAA NEXRAD Level II radar (reflectivity and radial velocity), NWS Local Storm Reports and warnings via the Iowa Environmental Mesonet, the NOAA NCEI Storm Events Database, NWS Area Forecast Discussions and Terminal Aerodrome Forecasts, rawinsonde soundings, and parcel/geocoding data.
Does the report prove that damage occurred?
No. Conclusions are framed as plausibility and consistency with the observed conditions — not confirmation that damage occurred at the structure. They are produced UNVERIFIED until a credentialed meteorologist reviews and certifies them.
Can a meteorologist certify the report?
Yes. A Detailed Analysis can be reviewed and certified by a credentialed meteorologist who signs off on the conclusions.
How long does a report take?
A Storm Snapshot history returns in seconds; a Detailed Analysis is typically ready in minutes per storm.
