Lookout,
My guess is that you're referring to the excellent poster, Perry/(aka SouthernWx), someone for whom I have deep respect due to his knowledge of Atlanta area wx history and his ability to make very interesting and informative posts about it. This knowledge is partially due to his excellent records/recall from his older relatives, including one of his grandmothers, that cover as far back as at least to the 1940's. I wish he would resume his frequent posting, but I know his health isn't great. He helped inspire me to post similar Atlanta related info though from a somewhat different perspective (library based microfilmed ATL newspapers a big source instead of relatives since I'm from Savannah; also, mine was centered more on Atlanta, itself, and the N burbs as opposed to his family's area W and SW of town). Due to this, some have gotten us two mixed up, which is always an honor for me. I didn't join WWBB until much later....late 2001 (so, I'm a relative newbie in comparison) when I posted those op. GFS (then called MRF/AVN) cold bias tests ad nauseum during that winter of false frigid alarms on the MRF/AVN. I think even you got sick of them..can't blame you lol...but I still don't regret doing them because the bias was absurdly ridiculous and I thought that was the best way to display it.
Let me know if it is Perry. I'm just educatedly guessing.
