4 p.m. By midafternoon Thursday, temperatures were dropping in central Oklahoma. Precipitation during the afternoon is expected to continue into the overnight hours.
“And that will probably turn to freezing rain overnight,” Matthew Day with the National Weather Service's Norman Forecast Office said Thursday afternoon. “We're looking at mainly after midnight, when it will start changing over to freezing rain.
“We're still looking at light amounts, probably not more than 1/10th of an inch of ice accumulation.”
Day said central Oklahoma might get up to 1/10th of an inch of ice accumulation and other areas, such as far northwest Oklahoma and southeast Oklahoma may have less.
As far as early Friday in central Oklahoma, Day said if there is icing it “might cause some concerns on bridges and overpasses, but I don't think it will be too big of a travel concern, other than that.”
While the amount and type of freezing precipitation may vary, the cold temperatures are a certainty.
“Tomorrow is going to be very cold,” Day said. “Especially with the winds up, we're looking at wind chill values down into the teens.
“With the actual temperatures, the highs will be in the 30s.”
A winter weather advisory for much of the Norman Forecast Office's coverage area remains in effect until 6 a.m. Saturday.
At 4:40 p.m. Thursday, temperatures at Oklahoma Mesonet stations varied from 23 degrees in the western Oklahoma Panhandle at Kenton to 71 degrees at Durant in southeastern Oklahoma.
11:10 a.m. Tree branches could snap and cause power outages from icing overnight and through Saturday morning in parts of Oklahoma. Less than an inch of sleet is also possible. Icing of tree branches could cause limbs to snap and fall on power lines, the National Weather Service reports. Power outages are possible. A weather advisory for colder temperatures, sleet and ice has been issued through 6 a.m. Saturday. Check NewsOK.com for updates.
