A fun post from our local NWS office regarding snow cover on Thanksgiving dating back to 1955. Despite all the predictions for this year's winter, we may at least have some luck on this one! From all of us at TCMETSOC, we hope you have a Happy Thanksgiving, and drive safely if you are traveling!

The EPA is starting to allow the use of pesticides containing PFAS on food. The move is part of an effort to roll back the regulation of PFAS — also known as "forever chemicals" because they don't break down easily in the environment.

"As they scoured well records & years of data, they zeroed in on a significant clue: The purges were occurring near wells where companies were injecting oil field wastewater at excessively high pressure, high enough to crack rock deep underground & allow the waste to travel uncontrolled for miles."
Oil regulators claim Oklahoma's wastewater incidents are under control.
But our reporting with @readfrontier.bsky.social shows the state is still dealing with dozens of instances of toxic waste spewing out of the ground, one of which killed about two dozen cows in Sept.
