The risk

Every case built on a free radar screenshot is one motion in limine away from collapse. Raw radar is not evidence. It is a probability estimate. Opposing experts know it. Courts know it.

Why it holds up

Four pillars of admissibility — every packet.

01 · Qualified expert

Named, court-qualified meteorologist.

Every report carries a named senior meteorologist's signature. CVs, prior-testimony history, and deposition availability provided with the packet.

02 · Peer-reviewed method

Transparent, published methodology.

The full blending methodology — radar, NWS observations, ground-truth storm reports, meteorologist review — is documented and peer-referenced. No black box.

03 · Chain of custody

Source data preserved and exportable.

Every parcel report ships with the underlying radar sweeps, NWS observations, and storm-report records that feed it. Opposing experts can inspect the inputs.

04 · Error rate published

Known uncertainty bounds.

Every metric ships with a stated uncertainty interval. Daubert's "known or potential error rate" prong is satisfied in writing.

From intake to trial

A packet in under 24 hours. An expert on the stand on request.

Submit the address and date of loss. Within one business day you receive a sealed Forensic Plus packet, routable directly to opposing counsel during discovery. If the case proceeds, your named meteorologist is available for deposition, trial testimony, and rebuttal.

We handle scheduling, travel, and demonstratives. You handle cross.
