A forensic meteorologist is a weather scientist who reconstructs past atmospheric conditions to determine what the weather was at a specific location and time. They analyze archived data, radar imagery, satellite observations, and atmospheric models to produce expert analyses used in insurance disputes, legal proceedings, accident investigations, and other situations where weather conditions are a factual question.
The word "forensic" means "relating to the application of scientific methods to the investigation of facts." A forensic meteorologist applies meteorological science to investigate what the weather was, not what it will be. While most meteorologists focus on forecasting future conditions, forensic meteorologists work backward, piecing together what already happened.
What Forensic Meteorologists Do
A forensic meteorologist's work goes well beyond looking up historical weather data. Their analysis typically involves several layers of investigation.
Retrieving and reviewing surface observations
They start with archived data from ASOS and AWOS monitoring stations, the same hourly records of temperature, wind, precipitation, and visibility that form the basis of most weather documentation. But they do not stop here.
Interpreting radar data
Doppler radar provides spatial and temporal detail that surface stations cannot. A forensic meteorologist can analyze radar imagery to evaluate whether hail was present at a specific location, estimate hail size based on radar reflectivity signatures, track the path and intensity of a thunderstorm as it moved through an area, and identify features like microbursts or rotation that indicate tornado potential.
Analyzing satellite imagery
Satellite data shows cloud development, storm structure, and the evolution of weather systems from above. Combined with radar and surface data, it helps build a three-dimensional picture of the atmospheric conditions.
Applying atmospheric modeling
When the location in question is between monitoring stations (which is common, since stations are typically at airports), forensic meteorologists use atmospheric models to interpolate conditions. This is particularly important for establishing what conditions were like at a specific property that may be miles from the nearest station.
Producing expert reports and testimony
The final product of a forensic meteorologist's work is usually a written report explaining their analysis, methodology, data sources, and conclusions. If the case goes to trial or arbitration, the meteorologist may provide deposition or courtroom testimony, explaining their findings in language that judges and juries can understand.
Education and Credentials
Forensic meteorology is a specialization within the broader field of atmospheric science. Most forensic meteorologists hold at least a bachelor's degree in meteorology or atmospheric science, with many holding master's or doctoral degrees.
The most widely recognized professional credential in the field is the Certified Consulting Meteorologist (CCM) designation, issued by the American Meteorological Society (AMS). The CCM designation requires a combination of education, professional experience, demonstrated competence, and adherence to ethical standards. While the CCM is not required to practice forensic meteorology, it is widely respected in legal settings and is often cited as a qualification indicator.
Other relevant credentials include the Certified Broadcast Meteorologist (CBM) seal from AMS (though this is more common in broadcast meteorology), membership in professional organizations such as the National Council of Industrial Meteorologists (NCIM), and state-specific certifications where applicable.
When Forensic Meteorologists Are Retained
Forensic meteorologists are typically brought into situations where the weather conditions at a specific time and place are either critical to the outcome or actively disputed.
Personal injury litigation
When a slip-and-fall, auto accident, or workplace injury involves weather conditions, attorneys may retain a forensic meteorologist to document what conditions existed at the time of the incident. For more on how weather data applies to these cases, see Weather Data for Personal Injury Cases.
Property damage disputes
When an insurance company disputes whether weather conditions at a property were severe enough to cause the claimed damage, a forensic meteorologist can analyze radar data and surface observations to provide expert analysis of the conditions at the specific location. See How to Prove Weather Caused Property Damage for more context.
Construction delay claims
When weather delay claims involve significant liquidated damages and the project owner disputes the claimed conditions, a forensic meteorologist may be retained to evaluate the weather data and provide expert testimony about whether conditions met the contract's threshold definitions.
Criminal cases
Weather conditions can be relevant in criminal proceedings, from visibility conditions during an accident to whether weather created mitigating circumstances. Forensic meteorologists may testify about conditions that affected the events in question.
Aviation incidents
Weather is a factor in many aviation accidents and incidents. Forensic meteorologists analyze conditions affecting flight operations, including turbulence, icing, visibility, and wind shear.
What Forensic Meteorology Costs
Forensic meteorologist fees reflect the specialized nature of the work.
Typical fee ranges: Hourly rates for analysis and case review typically range from $200 to $500 per hour, with most cases requiring 10 to 20 hours of work. Written reports typically cost $2,000 to $8,000 depending on complexity. Deposition testimony costs $2,000 to $5,000 per day, and trial testimony costs $3,000 to $7,500 per day.

Forensic Meteorologist vs. Weather Evidence Report
The distinction between a forensic meteorologist's report and a structured weather evidence report is important for choosing the right level of documentation.
Forensic Meteorologist
Expert AnalysisAnalyzes Doppler radar data to determine hail size, storm paths, and precipitation intensity at specific locations
Interpolates conditions between monitoring stations using scientific models
Forms expert conclusions about what conditions existed at a specific micro-location
Provides deposition and trial testimony, answers cross-examination questions
Weather Evidence Report
Structured DocumentationHourly temperature, wind, precipitation, visibility, and pressure from ASOS/AWOS stations
Warnings, watches, and advisories that were in effect at the location during the date
NCEI Storm Events Database entries for the county, including type, magnitude, and narratives
Structured assessment based on defined meteorological thresholds with documented data sources
Both rely on observation data recorded by monitoring stations within national weather observation networks. The difference is whether you need someone to interpret that data (forensic meteorologist) or whether you need the data itself presented clearly (weather evidence report). For more on what weather evidence reports contain, see What Is a Weather Evidence Report?
For many insurance claims, demand letters, and initial case evaluations, a structured report provides a clear summary of the recorded weather conditions. For complex litigation, disputed conditions, or cases requiring expert testimony, a forensic meteorologist may provide deeper analysis.
How to Find a Forensic Meteorologist
If your situation calls for expert meteorological analysis, several resources can help you find a qualified practitioner. The American Meteorological Society (AMS) maintains a directory of Certified Consulting Meteorologists. Expert witness directories such as SEAK, JurisPro, and the Expert Institute list meteorology specialists. The National Council of Industrial Meteorologists (NCIM) also provides referrals to consulting meteorologists.

Frequently Asked Questions
A forensic meteorologist reconstructs past weather conditions at a specific location and time. They analyze archived observations, radar data, satellite imagery, and atmospheric models to determine what conditions existed, and they produce written reports and testimony explaining their findings.
Most hold at least a bachelor's degree in meteorology or atmospheric science, with many holding graduate degrees. The Certified Consulting Meteorologist (CCM) designation from the American Meteorological Society is the most widely recognized professional credential in the field.
Expert analysis is typically appropriate when the case involves significant financial exposure, when conditions at the specific location are disputed, when radar interpretation is needed, when the opposing party has retained a weather expert, or when the case is heading to trial.
Hourly rates range from $200 to $500, with full case reports typically costing $2,000 to $10,000 and trial testimony reaching $3,000 to $7,500 per day. See The Cost of a Forensic Meteorologist Report for a complete breakdown.
No. Weather forecasters predict future conditions. Forensic meteorologists investigate past conditions. The skill sets overlap but the application is different. Forensic meteorologists focus on historical reconstruction and expert analysis rather than prediction.
Yes. Forensic meteorologists regularly provide deposition and trial testimony as expert witnesses. Their testimony is typically evaluated under the Daubert standard (or state equivalents), which assesses whether the expert's methodology is scientifically reliable. For more on how weather evidence is introduced in court, see Can You Use Weather Data as Evidence in Court?
The Bottom Line
A forensic meteorologist is a specialized weather scientist who reconstructs past conditions using multiple data sources and expert analysis. They are often involved in high-value litigation, complex weather disputes, and cases where conditions at a specific micro-location are central to the case.
For many common documentation needs, however, the level of analysis a forensic meteorologist provides exceeds what the situation requires. Understanding the distinction between expert analysis and structured documentation helps you match the right resource to your specific situation and budget.
