What the finished report looks like.
Every report is built around your incident window. The preview shows the structure of a delivered report with the details blurred. Your report carries the real values, the citations, and the meteorologist's signature.
Delivered reports include the conditions timeline, accumulation and temperature record, radar and observation citations, active warnings, and the signed meteorologist summary for your window.
What is a forensic weather report?
Weather records are scattered across stations, radar archives, and official bulletins, and none of them were taken at your exact address. A forensic weather report closes that gap. A meteorologist reconstructs the conditions at the incident address itself, hour by hour, and writes up what happened in language a claims file or a courtroom can use.
That matters because cases rarely turn on the nearest airport's daily summary. They turn on whether ice had formed in that parking lot by 7am, whether the hail at that address was large enough to damage that roof, or whether visibility on that road had dropped before the collision. The report answers the question the case is actually asking.
WDS prepares these reports on request for attorneys, insurers, risk managers, property owners, and private individuals at any US address, going back 10 years. Each one is scoped to your matter, quoted individually, and signed by the meteorologist who prepared it.
Every detail the case needs, documented.
Reports are scoped to your matter. A slip and fall report leans on ice and refreeze detail. A hail claim leans on storm timing and intensity. These are the building blocks.
Hour-by-hour conditions timeline
A reconstructed timeline of conditions at the incident location, covering the event window you specify plus the lead-up period that matters for your case.
Precipitation type and amounts
What fell, when it started, when it stopped, and how much. Rain, snow, sleet, freezing rain, and mixed precipitation are broken out separately.
Snow and ice accumulation
Snow depth, new snowfall, ice accretion, and melt and refreeze behavior across the period, including overnight refreeze windows relevant to slip and fall claims.
Temperature and freeze-thaw record
Hourly temperatures, highs and lows, and every crossing of the freezing mark during the report window.
Wind, visibility, and storm conditions
Wind speed, gusts, and direction, plus visibility and storm intensity where hail, straight-line wind, or severe weather is at issue.
Lightning activity
Cloud-to-ground lightning near the address during the window, when lightning is relevant to the claim.
Radar and official observations
Radar imagery for key moments and the surrounding official surface observations that support each finding, cited by station and time.
Warnings and advisories in effect
Every watch, warning, and advisory active for the location during the window, with issue and expiration times.
Written meteorologist summary
A plain-language narrative from a degreed meteorologist stating what the weather was doing at the address, written to be read by attorneys, adjusters, and juries.
Built for claims, cases, and disputes.
Slip and fall claims
Establish surface conditions at a specific address and time. Snow, ice, refreeze, and the precipitation history leading up to the incident.
Insurance claims and disputes
Verify hail, wind, flooding rain, or winter weather at a covered property on the date of loss. Support or challenge a claim with documented conditions.
Legal cases and litigation
Court-ready weather documentation for plaintiff or defense, with sources cited and expert support available for depositions and testimony.
Accident reconstruction
Visibility, precipitation, road-icing conditions, and wind at the time and place of a vehicle or workplace accident.
Construction and schedule disputes
Document the weather behind delay claims, force majeure notices, and disputed work windows.
Contract and SLA verification
Independent verification of weather thresholds written into service contracts, from snowfall triggers to rain days.
Every request is quoted individually.
No two matters need the same report. A single morning at one address is a different job than a two-week storm across three properties. So we do not publish a flat price. You describe the scope, we quote it, and the price is fixed before any work starts.
Tell us what you need
Submit the incident location, the date or date range, and what the report needs to establish. A meteorologist reviews every request.
Get a scoped quote
We reply within one business day with any clarifying questions and a fixed quote for your specific request. No subscription, no commitment until you approve.

Forensic weather report FAQs.
What is a forensic weather report?
A forensic weather report is a documented reconstruction of past weather conditions at a specific address and time, prepared by a meteorologist for use in legal cases, insurance claims, and disputes. It states what the weather was doing at that address, with sources cited, so the facts can stand up to scrutiny.
How much does a forensic weather report cost?
Pricing is quoted per request. Cost depends on the length of the weather window, the number of locations, the depth of analysis, and turnaround time. Submit a request with your scope and we reply with a fixed quote, typically within one business day.
Can the report be used in court?
Yes. Reports are prepared and signed by a degreed meteorologist, document their sources, and are written for legal and insurance use. Expert consultation and testimony support are available as a separate engagement if the matter advances.
How far back can a report go?
We cover any US address going back 10 years. Tell us the date and address and we will confirm coverage before quoting. There is no charge to ask.
How fast can I get a report?
Typical turnaround is a few business days after approval, depending on scope. If you have a filing deadline, say so in the request and we will confirm whether we can meet it before you commit.
What do you need from me to start?
Three things: the location (a street address or intersection), the date or date range, and what you need the report to establish. Anything else, like incident time or photos, helps us scope the work but is not required to get a quote.
Not sure if your matter needs a full report? Send the request anyway. A meteorologist reads every submission and we will tell you honestly if a report will help.
