TSA’s current thoughts from 3:30 AM is 1-2 inches across NE OK, but said they’re going with a. Conservative approach right now.

06z nam with a shift north.

Canadian has actually done really well this winter. Its sometimes been the first to sniff something out and then the euro comes around. Same deal here. Liking the latest Euro run!

Once again.....looking like Tulsa and NW AR barely miss out on one. going to be 34 degrees and heavy rain, and that'll just piss me right off lol.

I know......

My interest is piqued.

I'm thinking this last half of January is our best shot for the winter to get something substantial. I've got a good feeling.

This Thurs-Sat system has the makings of something great IF we can get the cold air to stick around. I say great, but if we get anything it would be an ice storm. But you know what? Give it to me.

18Z NAM Deformation zone smack centered over Tulsa.

I think the NAM is following in the Euro and HRRR's trends.

I mean, that’s really far south.

Also has Tulsa getting .2 inches of freezing rain. If the NWS buys this run, and the HRRR continues to reflect it, I think they'll expand the winter storm watch.

LOCK. THIS. IN.

Last night's run for reference.

12Z Euro is reflecting the 16Z HRRR right now.

What I'm getting at is, here is the 12Z HRRR run and the latest 16Z both at 4AM tomorrow morning. In the 12Z it appears that it's already beginning to wrap up to pump out the totals in N OK, but in the 16Z it's practically entirely in NW TX. What does this mean, if anything at all? Or am I obsessing, lol.

Question for those more meteorologically inclined. What is it going to take to eek that deformation band more east? A more negatively tilted trough? more southern storm track? Etc Just trying to figure out what I should be on the lookout for when watching the HRRR.

It's so close to Tulsa it HURTS. I'm just praying that when the storm develops that deformation band is just 20 miles closer....I don't need to be dead center with 6+ inches, I just want 3. If I didn't have a 6 month old that hardly sleeps, I'd just get in my car and chase some snow! To think....I could chase tornadoes and then snow just hours apart in the same geographical area!

I know these 18Z runs include old upper air data(aka not the on shore sampled stuff) so I’d say it’s not locked in. Plus, they’re literally going to wait until the HRRR is in 18 hr range to make those calls.

The cold front finally gets a push into Northeast Oklahoma Friday afternoon and through Northwest Arkansas late Friday evening/overnight Friday night as the main upper low shifts eastward into Texas. Behind the cold front...much colder air is forecast to filter into the region Friday night which will allow for precip to transition over to a wintry mix of freezing rain and sleet into Saturday morning from northwest to southeast. The greater wintry mix is expected across Northeast Oklahoma before the nose of warmer temps aloft can be eroded. Ice accumulations of a few hundredths of an inch will be possible with to up toward a tenth of an inch for some location along the Oklahoma Kansas border. Surface temps will continue to fall Friday night through much of the Saturday as the upper low shifts east into the CWA and then Northeast into Missouri Saturday afternoon. By Saturday afternoon temps in the 20s to mid 30s are forecast from north to south. These temp profiles combined with moisture wrapping around the upper low will aid in a transition to all snow during the day Saturday from west to east before tapering off and exiting by Saturday evening. Also behind the exiting low...gusty northerly winds in the 20 to 30+ mph range will be possible which could create areas of blowing snow Saturday morning. At this time...snow accumulations of 1 to 3 with locally higher amounts could be possible along and north of I-44 with around 1 inch or so for far Northwest Arkansas before the precip ends. With these amounts and also the possible ice amounts a winter storm watch will be issued across parts of the Oklahoma Kansas border in Northeast Oklahoma Friday night into Saturday.

Tulsa just barely excluded from Winter Storm Watch.

I've been watching it past few runs. I haven't said much because, well...1 thing at a time right? But that is a mean ice storm, not to mention afterwards there's 1 day above freezing and then it doesn't get above freezing for a while.

Well, hellooo beautiful.

OKC updated their snowfall map, also shows an eastward trend.
