Here’s the latest on our potential Winter Weather event coming up for Friday into Saturday morning.    Below is the very latest 00Z run of the High-Res NAM Model showing temperatures at around 11AM Friday morning across Oklahoma.  Temperatures will slowly fall through the day down to near freezing for most by 5-6 pm. (With the exception of far SE corner of the state)

The much advertised Arctic front will move into Oklahoma late Tomorrow night into Friday AM. Temperatures will slowly fall to near freezing by late in the day Friday across Central/Southern OK.


Rain will develop across portions of Western N TX into Central OK by Friday AM. Surface temperatures initially will only support a Cold rain, however as we cool this will likely change over to a Mixture of Sleet/Freezing Rain in the late morning to early afternoon hours (Possibly as early as 9-10 AM) from North to South (Mainly along and S/E of Interstate 44) Keep in mind Surface temperatures have been rather warm lately so it would take a prolonged event for us to have significant impacts on travel! At this time I only expect patchy areas of Ice on area roads with the main problem areas being elevated Surfaces like Bridges/Overpasses.


As we start to cool in the upper levels any lingering Frz Rain will change over to a Light Snow by late Friday evening likely between 8-9 PM this will last through daybreak on Saturday. I expect accumulations to be rather light from mainly a dusting to up to 1.5 to maybe 2 inches.   It’s possible some isolated locations could pick up locally higher amounts (See more on this below) .


This is a more technical discussion here: I’m showing you the 500 MB level – This system has appeared more sheared out in previous runs but is more “closed off” on this latest run of the Nam. So this is a plus if you want to see some snow!  It’s not entirely out of the question that we could see a Moderate to Heavy Snow band setup somewhere over Central East Central and possibly down into Southern OK late Friday into the early morning hours of Saturday.  If this were to occur we could see an enhanced area of Snowfall totals as shown below.


Latest Nam model showing possible Snow Totals by Saturday AM.. Keep in mind some of this is likely on the higher-end side but it gives you an idea. I do think it’s possible that some isolated spots see up to 1.5″ to 2 inches.


Here’s a look at my Latest Storm Impacts for Friday afternoon – Midday Saturday. We will see some Ice and Snow but it appears at least at the moment that both should only be minor issues! Travel impacts will be low but again just use common sense and exercise caution especially on those bridges and overpasses!

So as it stands right now this system will be a quick hitter and thus this should limit the overall impacts.   We dry out going into Saturday afternoon and both Christmas Eve and Christmas Day look dry with daytime highs in the upper 20s north to lower to mid 30s down South.  Lows will be in the low to mid 20s statewide.        A Bigger Winter Storm could impact Oklahoma towards the middle to end of next week 28,29th , 30th +/- a few days!   I’m watching it closely and will have more on this over the next few days.     As always if I see any changes in this you’ll be the first to know and I hope you have a Merry Christmas!
