Gusty north winds will blow in as a cold front moves into eastern Oklahoma and northwest Arkansas overnight.
Much colder air will be sweeping in from Canada and surging southward so that Sunday and Monday are not expected to get above freezing, according to WARN Team meteorologist Dick Faurot.
"Strong northerly winds on Sunday will be on the order of 20 m.p.h. with much stronger gusts bringing wind chill values down into the teens or even single digits at times," Faurot said.
"The winds will not be quite as strong on Monday, but it will still be brutally cold with morning lows in the teens and daytime highs in the 20s to near 30 at best."
Light snow or flurries are possible just about anytime both days, but most of the winter precipitation is expected to fall over far western Oklahoma and south of Interstate 40.
If you are traveling west, be weather aware as the National Weather Service has issued a winter storm warning and winter storm advisory for northwestern Oklahoma from 6 p.m. Saturday to 6 a.m. Monday.
Temperatures are likely to go back into the 40s on Tuesday and Wednesday with another chance of wintry precipitation later next week and into the weekend.
"We are being rather conservative with respect to the winter weather potential later next week as the uncertainties are just too great to have any real confidence in a snow or no snow forecast," Faurot said in his weather blog.
