Above image is a forecast based SOLELY on the computer model average.

Graphic includes 12z Euro, 15z SREF, 18z NAM/GFS/SREF. I also plugged in higher snow to liquid ratios, ranging from 11:1 in New London County to 14:1 in Litchfield County.

Model details:
12z Euro: 0.2" minimum to 3.1" maximum
15z SREF: 0.3" minimum to 4.4" maximum
18z NAM: 0.1" minimum to 3.9" maximum (corrected minimum value)
18z GFS: 0.2" minimum to 5.5" maximum
18z RGEM: 0.2" minimum to 3.2" maximum 

Based on this, the GFS shows the most, with the Euro/RGEM showing the least. Interestingly enough, I generally have the highest confidence in the Euro and RGEM.

Stay tuned as I will have my specific snow forecast later this evening.
