Wednesday Snow Part 3

Looking over some of the new data that is coming in tonight.

So far, data from just one of the models (the NAM) is in. The model seems to be coming in slightly wetter than earlier today. Snow to liquid ratios could be anywhere from 12:1 to maybe 16:1. The 16:1 may be pushing it a little because we aren't that cold at the surface. However, a 1,500' thousand feet up in the air we are -5 degrees Celsius.

Here is what the model is suggesting for moisture available and the potential snow using the ratios above.

CITY | Liquid | Snow (12:1)/(16:1)

  • Blytheville, AR - 0.14" | 1.6" / 2.2"
  • Cape Girardeau, MO - 0.02" | 0.2" / 0.3"
  • Dyersburg, TN - 0.16" | 1.9" / 2.5"
  • Jackson, TN - 0.17" | 2" / 2.7"
  • Jonesboro, AR - 0.16" | 1.9" / 2.5"
  • Murray, KY - 0.05" | 0.6" / 0.8"
  • Poplar Bluff, MO - 0.05" | 0.6" / 0.8"
  • Sikeston, MO - 0.05" | 0.6" / 0.8"
I think it will be possible for a half inch to perhaps a few isolated spots of 2" of snow to fall through mid-morning Wednesday.

As previously mentioned, a Winter Weather Advisory is in effect until noon Wednesday for parts of southeast Missouri, western Tennessee, northeast Arkansas and northern Mississippi.
