Initial models showed Tulsa “right on the line” between sleet and snow, he said.
“If that’s true, you could have a scenario where places like Bixby and Broken Arrow get 2 inches of sleet, and northwest Tulsa gets 6 to 8 inches of snow,” he said.
“It looks like Tulsa will be in the sleet/snow zone where areas to the south could experience a lot of ice issues.
“The bottom line is that this is going to be a major winter event,” he said.
Precipitation will start as rain as early as Tuesday evening in some areas, then change to freezing rain, ice pellets and snow on Wednesday.
Precipitation will fall in the area Wednesday and Wednesday evening, with possibly a second round Thursday afternoon, he said.
“Wednesday to Thursday seems like the best time for the worst,” he said.
The weather service also said the cold wind will bring “very dangerous” wind chill readings from Wednesday evening through Thursday.
“It’s going to be very windy,” Piltz said, adding that getting around will likely become difficult. “You’re going to get a lot of blowing snow and blowing snow, especially in areas outside of town.”
