Forensic

Meteorology

Tornado path analysis: Meteorologists plotted the NWS tornado survey data relative to a site as one part of our analysis to determine approximate wind speeds.
Temperature analysis: Meteorologists reviewed time-series data to determine duration of freezing temperatures for a file related to frozen (burst) pipe damage.

WHAT WE DO

Haag provides forensic meteorology services in which our experts are able to analyze weather conditions at a given location for a certain date or range of dates. Our experts utilize local weather data such as surface observations, radar, and/or storm reports. Forensic meteorology has proven to be a valuable resource when weather conditions are believed to have been a contributing factor for insurance disputes, personal injury cases, wrongful death lawsuits, motor vehicle accidents, etc. This type of analysis can be performed on its own or in conjunction with an engineering evaluation by one of our licensed engineers.

For weather-related cases, we employee several meteorologists qualified to perform meteorological reviews. All of our meteorologists have obtained their Certified Consulting Meteorologist (CCM) designation from the American Meteorological Society or work under the direct supervision of a CCM. Meteorologists that have obtained a CCM must pass a rigorous examination process exhibiting a high degree of technical proficiency and moral character.  

Regardless of discipline, our experienced meteorologists have provided expert testimony in cases involving extreme winds, hail, heavy rain and flooding, roof collapses, slip and falls, snow and ice, vehicle accidents, criminal cases, etc. Our clients include insurance companies, attorneys, property owners, and more.

Meteorological services include

  • Detailed meteorological analyses of weather events (hail, tornadoes, thunderstorm winds, tropical systems, etc.)
  • Precipitation and temperature time history reviews
  • Wind versus wave data analysis
  • Winter weather evaluation (snow, black ice)
  • Weather data analysis for agriculture applications
  • Drought analysis
  • Maritime conditions
  • Storm surveys
  • Slip and fall support
  • Expert witness testimony
Wind analysis: Climatological review of maximum yearly wind gusts relative to a provided storm date which had a peak measured wind gust of 18 mph (shown in red).
Snowfall analysis: Case involved a slip and fall incident. Precipitation maps were used in conjunction with nearby surface observations to determine the arrival time of snowfall and the total accumulation.
Hail analysis: Client was provided with a photograph of a hail stone taken a few miles from a site. Meteorologists plotted the location of the photograph and site and showed that the storm that produced the photographed hail did not pass over the property.

Fred Campagna, CCM, CBM, Director of Forensic Meteorology, is a veteran on-air meteorologist with twenty-six years of experience. Fred has worked as a forensic and consulting meteorologist for more than twelve years and has worked on hundreds of civil and insurance-related legal cases, providing detailed written reports plus courtroom, deposition, and private arbitration testimony.

Pat Hyland, CCM, Senior Forensic Meteorologist, is a meteorologist with over ten years of experience providing meteorological consulting services. He previously worked for the NOAA National Severe Storms Laboratory where he transitioned cutting-edge science, research, and technology into implementation within the National Weather Service. His past research has included severe weather radar applications, probabilistic hazard information and impacts, cloud microphysics, and lightning.

Jared Leighton, CCM, Senior Forensic Meteorologist, is a meteorologist with seventeen years of experience forecasting for the National Weather Service (NWS) across numerous geographic areas. Most recently he forecast for the NWS in Kansas City, providing life-saving severe and winter weather warnings as well as post-storm snow, tornado, hail, and wind analyses for Kansas City and its surrounding areas.  His past formal research comprised all types of severe weather, but focused primarily on field observation, collection, and remote detection of large hail. 

Kyle Pittman, Associate Forensic Meteorologist, is a meteorologist and is also currently a PhD student and graduate teaching assistant in the Department of Earth, Atmosphere and Environment at Northern Illinois University. His current research work is examining the impacts of climate change on tornado outbreaks, and he has past research experience on understanding supercell thunderstorm environments, heavy rainfall events, and tornadogenesis.

Tim Marshall, P.E., Forensic Engineer/Meteorologist Emeritus, has a combined background in meteorology and civil engineering. He was a key contributor to the development of the Enhanced Fujita (EF) Scale used operationally by the National Weather Service since 2007 to rate tornadoes.

Precipitation analysis: Daily precipitation totals for an agricultural site. This included radar-indicated accumulation as well as surface observations.
Radar analysis: Base radial velocity radar analysis of a tornado relative to a property.
