It takes a lot to get temperatures below zero as far south as Oklahoma City, but that’s precisely the arctic airmass we have coming down early next week.
This is just one model forecast for next week, but it shows the potential for a brutally cold morning on Tuesday. There will also be a chance of some wintry weather, but the overall coverage and impacts aren’t entirely known at this point.
What I think is baked in are the coldest temps of the season by far. This weekend is an excellent time to take steps to protect animals, livestock, and plumbing, to be sure.
