We should know by Thursday into Friday whether Tulsa will have freezing rain or ice this weekend.
We're told it depends on the temperature when the precipitation falls.
Robert Darby at the National Weather Service tells us, "It's difficult sometimes to gauge exactly what the temperature is going to be at the surface especially several days out."
Darby says another factor is how shallow and cold the air mass will be will determine whether we have rain or ice coming down.
"I would say, by Thursday and especially into Friday, we will have a better handle on how some of the short term models will be handling how shallow and how cold this air mass is going to be into Saturday."
