Springfield updated their WSW and Winter weather page after the 3 PM hour. Greater than 6" went up to 73% here. Greater than 8" at 47%, but the "Expected Snowfall" is 8". Hmm.
21z RAP is nice for everyone.
I'm pretty confident on getting 4" IMBY, somewhat confident I may see 6", but anything over that I'm not confident in seeing. Too close to the 850 MB line and I've seen too many times where it ended up being warmer than forecast or there was some layer of the atmosphere that was just a little warmer than models thought which ended up giving more sleet. Despite the cold surface temps, the ratios won't be that great due to this warmer layer being nearby as well. So in general I think 4-6" is a good bet for me.
Just looking at the 10:1's for here at hour 84, Euro 9.3", GFS 9.4", GEM 7.0", NAM 7.4", RGEM 8.5"
Looking like maybe 6+" is a good possibility assuming no warm nose funny business.
06z NAM continued going north, 06z GFS went farther SE.
Winter Storm Watches are now in effect for some areas.
Springfield:
" It is worth mentioning that the ECMWF Extreme Forecast Index indicates a potential for an anomalous snowfall, and the Shift of Tails indicates that at least 50 of the ECMWF ensemble members are forecasting a higher-end snow. Again, the warm nose will be a big determining factor."
Looks like Wichita is forecasting 6-12" or so of snow.
Tulsa will issue a Winter Storm Watch in 12-24 hours.
