Owasso has been between two bands of snow most of this time, so I’m not SUPER happy about that, but still plenty of time to go!

Snowing in Owasso! Not super heavy, it’s light and fluffy snow, but there’s a moderate to heavy band on its way to Tulsa.

I didn't even see it on the radar...interesting. I would think that means the layer is cool all the way through though.

It's nothing profound, but you can see the sleet on the rooftops and my car from this AM.

Thanks for the great update! I live right on the Collinsville/Owasso line and woke up at 4:30 to sleet blowing into my window, sounded like someone hurling sand at my house lol.

NAM and HRRR both getting on board with that 2nd wave of precip and giving 9+ inches for lots of people.

Heavy sleet here in Owasso. Woke me up.

Been noticing on the HRRR, sleet and freezing rain moving into Tulsa more and more with each run on the early morning wave.

TSA upping the amounts on their page.

Canadian backed off a little on amounts, but still showing 6+ inches.

I figured it would lol. My assumption is that it's generated by using a blend of models, and they don't actively make it themselves. So sometimes it has an error, or grabs an erroneous model run that sends it to the moon, etc. Point is, I don't usually take much stock in their decision support page lol.

You know...there is technically blizzard criteria wind gusts associated with this during the heavy snow..

Also, their decision support page went off the charts

TSA mentioning potential lake effect snow in north to south oriented lakes here in OK. Specifically mentions Lake Oologah, which I can confirm produced lake effect snow at my house last year during the intense cold snap. I'm just summarizing here, but they essentially said, that at a minimum, NE OK and NW AR should see 4 inches of snow, but could see 7-10 inches in a "reasonable worst case scenario".

In addition to the NAM, here was the 12Z of the HRRR, and still snowing.

NAM is looking interesting so far. Not sure what to make of it yet.

18Z NAM results. And still snowing...

TSA expanded the winter storm watch to it's entire area.

Latest GFS. On top of the warm nose receding to the SE, it really dumps some good snow on the back end of the storm Thursday night.

TSA.. WINTER STORM WATCH IN EFFECT FROM LATE TUESDAY NIGHT THROUGH THURSDAY EVENING... * WHAT...Heavy mixed precipitation possible. Precipitation starts off as freezing rain, then transitions to sleet and eventually snow as the event progresses. Ice accumulations of one tenth to one half of an inch possible. Total snow and sleet accumulations of 1 to 10 inches possible. * WHERE...Portions of east central, northeast and southeast Oklahoma and northwest Arkansas. * WHEN...From late Tuesday night through Thursday evening. * IMPACTS...Power outages and tree damage are possible due to the ice. Travel could be nearly impossible. The hazardous driving conditions will disrupt daily life later this week. * ADDITIONAL DETAILS...Emergency managers and first responders should continue to prepare for a winter storm later this week. A disruption to daily life is likely, with threats to life and property possible.

06Z NAM vs the 12Z NAM. BIG SE jump with the snow(and still snowing)

NAM with a SE nudge on the warm nose.

GFS nudged SE, 06Z Euro eeevveeeer so slightly nudged SE as well. NAM still doing it’s North trend.

Not the most profound image but this is from TSA.
