It’s time to focus on the strongest arctic front of the season heading to Oklahoma. This arctic airmass will have more of an impact than those prior. Each progressive front of this nature typically gets colder from here out over the upcoming winter season. So on with the details!

The front arrives Friday night into early Saturday morning keeping most of Oklahoma in the 20s during the day with wind gusts around 40 mph (equals wind chill values in single digits). Mid level energy will transverse the area generating thick cloud cover. At this point, a light wintry mix is expected with the passage of this front. There likely won’t be any significant travel issues in Oklahoma the way it looks now, but will need to watch for any changes that indicates stronger lift and better moisture to work with. Another weak upper wave will move through a couple days later which may spark another very light round of wintry precipitation. I cannot guarantee a winter-less Christmas Eve or Day as a few computer model ensemble runs indicate a storm system lurking with ice or snow. It should be cold with highs in the mid 20s regardless. Remember, it’s situations like this that need to be watched. That is, the cold air comes first, and once established in the overall global weather pattern, let the mayhem fly. This happens with quick moving upper level storm systems that produce some surprise winter weather events. Always a challenge to predict days and weeks out. BTW…I posted just one map below of the temperatures we could see Sunday morning should this front be 1. as strong as advertised, 2. we do get a little light frozen precipitation before hand, and 3. skies clear with a light wind. -AT
