Gusty North Winds Expected To Bring The Cold Back To Green Country

The rollercoaster ride of Oklahoma temperatures continues this week with a warm weekend followed by sub-zero wind chill values expected Monday morning.

If you're looking for something to blame, look north and up in the atmosphere to a stubborn polar vortex that continues to spin between Hudson Bay in Canada and the Great Lakes, according to News On 6 WARN Team Meteorologist Mike Grogan.

"This puts Oklahoma in a strong northerly and northwesterly flow in the jet stream," Grogan said in his Weather Blog.

"We're close enough to the core of Arctic air that we experience the cold blasts every several days from cold fronts that race into the region."

The cold air is expected to reach us Sunday evening and overnight as cold air races in from the north. The National Weather Service has issued a wind advisory that will be in effect from 10 p.m. Sunday to 6 a.m. Monday for several northeastern Oklahoma counties including Tulsa, Creek, Rogers, Mayes, Osage, Pawnee, Muskogee, Okmulgee, Wagoner.

Wind gusts as high as 50 mph are possible, especially along and north of Interstate 44, according to the National Weather Service in Tulsa. Gusts of up to 40 mph are expected. Because no moisture is riding the cold wave, fire danger will once again be high.

The burst of cold air will settle in for about two days, Grogan said.

"A wetter and cooler than normal pattern may develop as we head into February, which may heighten the chance for unsettled weather," Grogan said.

"This is great news for our fire concerns, but could mean wintry weather once again."
