Forensics Meteorology from AccuWeather Reveals Weather-Related Truths

AccuWeather, Inc's expert forensic meteorology group offers a wide range of products and services related to historical weather research and weather analysis to aid in determining the truth about weather-related incidents. 

Our staff has earned M.S., Ph.D. and Certified Consulting Meteorologist (CCM) distinctions, and bring decades of experience to the study of weather.

Here are a few of the many ways in which we can help you to determine the truth about what really happened:

Contact a forensic meteorologist for more information or a free consultation.

  • Comprehensive Site-Specific Verbal Briefing. We examine all available data and prepare our opinion of the weather conditions at the exact street address and during a given time frame where the incident took place (not just at the nearest airport!) This is the most detailed report available. After we have conducted our research, one of our meteorologists will discuss our findings with the client and will be available for consultation to determine the next step in the case. The verbal briefing often leads to a written report. 
  • Comprehensive Site-Specific Written Report. A written report, signed by three meteorologists presenting our opinion, to a reasonable degree of scientific certainty, as to the weather conditions at a particular place during a given time frame. 
  • Depositions. Sworn pre-trial testimony of our findings can be provided by one of the AccuWeather forensic meteorologists. A deposition can be done at the AccuWeather office or at a location of the client's choosing. Our experts combine a Ph.D. in meteorology and the Certified Consulting Meteorologist distinction to give you the best possible expert for your case. Video and audio conferencing is available. 
  • Trial Testimony. Our weather experts have the experience and skills to explain complex weather conditions to a jury in a way that is easily understandable. We have participated in more than 100 trials across the country for both plaintiffs and defense. Video and audio conferencing is available. 
  • Courtroom Graphics and Animations. Graphs, tables, charts, maps, animations or other items requested by a client that are used in court in conjunction with testimony. These items are generally produced in-house by the AccuWeather graphics department, whose graphics are used by hundreds of television stations and newspapers to explain the weather to the public each day. 
  • Hourly Surface Weather Observations. Hourly weather data from any official National Weather Service reporting station can be supplied, including any or all of the following: temperature, dew point, relative humidity, cloud cover, precipitation, snow depth, visibility, wind direction, and wind speed. These hourly observations are typically available for the airport nearest to the site in question and can cover a range of 24-hours or longer. These observations are decoded by a meteorologist and put into an easy-to-read chart. Each set of hourly surface weather observations is accompanied by a letter signed by one of our meteorologists explaining what the data show. Hourly surface weather observations are more detailed than any of the monthly products that are available. They are useful in many cases. 
  • Doppler Radar Data. Doppler radar products include wind velocity, precipitation intensity, one-hour precipitation totals, and storm total precipitation. Our experts will not just provide you with a Doppler radar image. They will study the image and provide you with a letter explaining what we see in the image to help you better understand the benefits of the Doppler radar image. Doppler radar data are useful for cases involving lightning, wind damage, motor vehicle accidents, and excessive rain, just to name a few. 
  • Lightning Strike Data. Several cloud-to-ground lightning strike products are available. The most basic products are the United States maps and the Pennsylvania and vicinity maps showing the location of cloud-to-ground lightning strikes during a calendar day. Also available are three products that give information on lightning strikes within a given radius of a site during a specified time frame. The first just tells the number of strikes. The second is a map showing the location of the strikes. The third is a listing of the exact time and distances from the specified location of each strike. Each lightning strike product is interpreted by a meteorologist and is accompanied by a letter signed by a meteorologist explaining the data. Lightning strike data is often utilized to help insurance companies settle lightning damage claims. 
  • Monthly Weather Summary Climatological Report. A monthly compilation available from many locations nationally and internationally of daily high, low, and average temperatures, normal temperatures, liquid precipitation, snowfall, snow on the ground, heating degree days, and cooling degree days. Also presented are monthly totals and departures from normal for most of the listed weather factors. This item is obtained from the AccuWeather database. Each climatological report is examined by a meteorologist before it is sent to a client. Climatological reports are a good first step product for cases that occurred reasonably close to an observation site. 
  • Local Climatological Data Monthly Summary. A summary of the weather conditions during a month available from 300+ United States observation sites. The Local Climatological Data Monthy summary includes daily averages, totals, and extremes for temperature, precipitation and wind, 3-hour surface observations, and hourly precipitation totals. These Local Climatological Data Monthly summaries are examined by a meteorologist before being sent to a client. Slightly more detailed than the climatological reports, the local climatological data monthly summary is also a good first step for many cases. 
  • Cooperative Observer Report. Observations from over 8,000 sites in the United States. Cooperative observers are trained volunteer observers that fill in the gaps between official airport hourly weather observation sites. Cooperative observers take observations once a day and send their monthly observation forms to the National Oceanic and Atmospheric Administration. Observations can include any or all of the following: high temperature, low temperature, average temperature, observation time temperature, liquid precipitation, snowfall, and snow on the ground. A meteorologist examines the cooperative observer reports for consistency and accuracy and includes a letter interpreting the information before they are sent to a client. Like climatological reports and local climatological data monthly summaries, the cooperative observer reports are a good first step in many cases.
