Look at mPING as it relies on actual observations, not the colors on radar maps. It currently has sleet up to Ada, OK, right in line with the Euro and HRRR. It does appear the NAM was too warm at the mid levels, though, as it had sleet up to I-40 where it’s currently all snow.

I mean you can just take a look at the radar and it's obvious that's sleet falling all through southern OK.

That too…reflectivity is bright and CC shows a clear boundary from roughly Ada to McAlester. Still means the NAM was too warm which has me injecting some hopium.

If that carries eastward, it would remove the lone model that’s really punching the mid level warmth way quicker/north than others.  I know I’ll flip but a few extra hours will make a big difference.

I’ll say this for the northwest crew, the models are really good out this way with these ratios. 18-20:1 is a good bet for the first 4-6 hrs of the storm before they slowly scale back, but even still, it’s probably 15:1 or better through 15z Sunday. After that, it’ll be a degrading column with the warm nose trying to approach, but flakes will be massive. Clumped aggregates that’ll still amount to 10-12:1 before a flip of any kind.

weird. its 10:1 map was more snow than the weenie ratio map

the snow maps aren't really useful for this storm.  figure out how much liquid you think you'll get as snow.  apply a ratio (i think 13:1 for you).  And make a forecast.  

I'll probably rip and read Euro QPF at 12z tomorrow.  Tweak a little.  It's really good that the Euro is King at QPF.  Cause it's super wet.
