Why AccuWeather For Forensics is Different

A Weather Report Alone Will Not Win Your Case. Expert Interpretation Will.

AccuWeather’s Forensic meteorologists are actively forecasting today. Not retired experts dusting off credentials, the same scientists tracking conditions right now are the ones analyzing your case.

We identify the details that change verdicts. Ice on one side of a street but not the other. Sun angle and slope affect road conditions at the exact time of an incident. The data alone will not surface these; our experts will.

We do not hand you a PDF and walk away. We tell you which data matters, so you can be best prepared for cross-examination and better challenge the other side’s interpretation.

Testimonials from Valued AccuWeather Clients

Every forensic report replaces uncertainty with fact — reducing litigation time, claims costs, and investigative overhead.

“I have been most pleased with the services of AccuWeather generally and with Steve (Wistar) specifically. A seasoned claims representative was present in court to witness Steve’s direct examination and said later that he was the best trial expert he has ever seen. You can be sure that when I next need a weather expert witness, AccuWeather and Steve Wistar will be the first to get the call.”

“I just wanted to let you know that [insurance company] won the case yesterday. When I spoke to the jury afterwards, all 8 of them indicated that you were the reason that [insurance company] received a defense verdict. They liked the plaintiff very much and wanted to find for her. However, they found your expert testimony regarding the weather to be so compelling that they changed their minds and found for [insurance company]. I thought you made a fantastic witness.”
