Personal Injury/Weather-Related Vehicular Accident Case
John’s analysis and reconstruction of the precise weather conditions at the time and location of my accident were remarkable. His report detailed the type of precipitation, temperature, and ice conditions. His expert testimony and report made all the difference, helping me settle the dispute with my insurance company quickly.
New York Attorney
Slip-and-Fall Case
I recently worked with John Bryant of Weather and Climate Consulting, LLC, on a New York slip-and-fall matter in which the ‘Storm in Progress’ defense was the central issue. John’s analysis of NEXRAD radar and site-specific temperature trends was surgical. He pinpointed the exact minute precipitation ceased and tracked the freeze/thaw cycle with a level of precision I haven’t seen from larger national firms. His work provided the objective evidence we needed to establish the timing of the hazard. He is easy to work with, highly responsive, and very cost-effective. If you have a case where the “when” and “how” of ice formation are in question, he is your guy.

Frequently Asked Questions
- What types of legal cases can benefit from forensic meteorology?
Forensic meteorology is valuable in a wide range of cases, including premises liability (slip and fall accidents), property damage from hurricanes, hail, or flooding, wrongful death involving lightning or severe weather, insurance claim disputes, and weather-related vehicle accidents. If weather played any role in an incident, a forensic meteorologist can provide scientific evidence to support or refute claims.
- How does John Bryant reconstruct past weather conditions?
John uses a combination of historical weather databases, NEXRAD Doppler radar data (including Level II Dual-Pol analysis), surface observation records, and advanced meteorological modeling. This multi-source approach allows him to pinpoint exact conditions, such as precipitation onset, wind speeds, or lightning activity, at a specific location and time, producing court-admissible findings grounded in the scientific method.
- Does John Bryant work for both plaintiffs and defendants?
Yes. John maintains a balanced practice, providing objective, independent analysis for both plaintiff and defense counsel. His testimony is always rooted in science, not advocacy, which makes his findings more credible and resilient under Daubert standards in federal and state courts
- What does the process look like from initial consultation to testimony?
After an initial consultation to review the details of your case, John gathers and analyzes all relevant meteorological data for the incident’s location, date, and time. He then prepares a comprehensive forensic weather report suitable for legal proceedings. If needed, he is available to provide deposition testimony and appear in court as a qualified expert witness to translate complex atmospheric data into clear, compelling narratives for judges and juries.
