JC - the map has my area I live at 0c - highly unlikely - that has happened only once in 12 years!!!! Temps at the Ionian sea rarely drop below 6c at night. Bur snow hopefully will be in dem der mountains from 2nd!
Jayne, the map I posted simply indicates upper air temperatures not surface.
-10 upper air temps would give you a good chance of lower level snowfall - (put simply)
Anyhow next week looks like some decent falls
