Forensic Meteorology is a field with no forensic scientists at all and unknow. Thus,the only thing I can do is to post what Wikipedia says about it:

Forensic meteorology is the process of reconstructing weather events for a certain location. This is done by acquiring local weather reports, radar and satellite images, and eyewitness accounts. Forensic meteorology is most often used in court cases for either insurance companies or a murder investigation.

<http://www.ametsoc.org/careercenter/careers.html> The forensic meteorologist retrieve and analyze archived weather record information which include surface observations, radar, satellite, river information, etc. They then reconstruct the weather conditions for the location in question. Some questions are when did the highest hurricane winds at a particular building occur, was sun in the eyes of the driver or was it cloudy at the time of the accident, or was lightning present when the house caught fire and are just a few examples of the types of questions forensic meteorologists answer for their clients. At times, forensic meteorologists are called to testify as expert witnesses in court cases that involve the weather.

For you interested about the ways to use forensic meteorology,I retrieved a list of generic meteorology tools (with links for descriptions and uses)
