The Jet stream shows a huge Arctic Blast approaching Oklahoma by late Wednesday! Temperatures may warm up briefly before taking a nosedive Wednesday Night with bitter cold air and very strong winds surging south across Oklahoma.  Temperatures will drop into the teens for highs and single digits for lows with wind chills well below zero right before Christmas!  The good news for travel is that we are not expecting a winter storm but some light snow and flurries possible as the cold air comes in Thursday.  So dangerously cold temps but no White Christmas the way it looks right now.
