The GEM model is showing snow on February 4th for the Ohio Valley. While it may seem heavy, we have equated 15mm out to about half an inch of liquid, which would equate to 5 inches of snow.. However, seeing just how massive and huge this storm is, I would not dispute the GEM showing a higher amount than is shown.
My confidence is very low, and this is only just a mention of a possible snowfall.
