It appears we have 6-8" of snow across parts of Tulsa county, with another inch or so possible before it tapers off in a few hours. There are motorists stranded all over the city and the state.
Christmas with the family was a quick one this evening, hard to tell how hard it's snowing with the way it's blowing around, but with the 8"+ still on the ground from last storm and what has come down today, it's getting pretty bad. In the back yard here (in town) we have a drift ALREADY pushing 6-7'. With the a good 1/4" of ice coating the trees from yesterday and the winds blowing like they are, I'm thankful for power, big old Elm tree in back has already dropped a BUNCH of branches, some 6"+ in size. Going to be INSANE by morning...
Will be interesting to see what the models tonight do with the low come after Friday 18Z, we could be in for a long duration event of ground blizzard conditions as the low parks itself over NW IA...
I had to pull off and go home, snow rate was near 4" hour at one point in Tulsa. Many persons stranded in vehicles. My nephew has been stranded on I40 west of OKC for 5 hours and national guard has advised them they will be stranded all night.
I had driven down the street to my sister in-laws and with in 20 minutes the tracks were completely covered.
The thing to think about up here is the fact there was a widespread area of a foot of snow on the ground, which got there from 2 storms, second being a windy ditch filler. Ditches out there in flat areas were just rather full of snow before anything has happened. It never got very warm but managed to compact down to maybe 7-8 inches. Then yesterday the ice hit this same area of eastern NE into nw Iowa. So you have a very icy crust on the snow before anything from this storm. Now stack a foot to foot and a half on that, with wind, drier variety.....and long duration of higher winds. It's going to have to be a nightmare to keep any of the roads open.

0z GFS indicating 1.25+ liquid equivalent in this area which should be rather high ratio snow. The potential is down right crazy. At this rate Omaha's 27 inch all time record snow depth could be looking to be broke. Perhaps not after this one, but given much of anything further. Yeah ok, so that is way ahead of things lol.
