I agree with that estimate as well. I would probably go closer to the 10" range. The satellite images of the storm are very impressive and the NAM estimated snowfall looks to be inline within the 10" range.


Wow, latest 12z GFS Bufkit estimate gives OKC up to 15" of snow, with ratios maxing out at 22:1! :eek:

It also appears some thunder will be possible in the heaviest bands later tonight.

Yep between 20:1 and 30:1


DEEP SATURATED DENDRITIC GROWTH LAYER ATOP COLD ARCTIC AIR MASS WILL YIELD VERY HIGH LIQUID SNOWFALL RATIOS AROUND 20-30:1.

For every inch of water, there would be 25 inches of snow. Its a lighter, fluffier snow.

Now this is just impressive.

The entire state has an at least 70% chance of receiving 4+ inches of snow.

I am now under a Winter Storm Warning here in SW MO: 5-8" of snow for us. The RUC and HRRR have been far superior to any of the others. I am sure that has to be frustrating for the meteorologists.

This is unbelievable! Parts Northwest Arkansas has received 30 INCHES just this morning!! A band set up and was putting out rates of over 3 inches per hour, and just sat over the same spot. I have gotten about 15 inches, but the News reporters are out in the snow in NW Arkansas and some is up to their waste. The Pro Met says this may have set the single day Arkansas snowfall record.

The winter storm way under-delivered here. I went to bed expecting 6-12 inches, and I woke up to find only around 4.

Still a decent snowfall, but nowhere near as bad as it could have been.

Amazing pics! Thanks for sharing. We wound up with 6" here. It has been quite an active last couple of weeks around here. Glad a warm-up is on the way now.

That is very very impressive. The coldest lows last night line very appropriately with the heaviest snow pack across Kansas, Oklahoma, Arkansas, and Missouri.

What's even more insane is that one of my coworkers pointed out how poorly GFS MOS did with the forecast for Bartlesville, OK for this morning. Remember, they hit -27F for the low today. The forecast was for a low of 7 degrees - 34 degrees too warm!

Sorry Bartlesville. Unofficial Mesonet observation of -31 from Nowata, OK. We'll see if this reading becomes official.
