This is the latest update to a blog I began on Dec 31st.
Newest model guidance shows little change in a late Sunday/early Monday arrival of very cold air. I have included a chance of LIGHT snow...given expected limited moisture conditions, a major snow event seems unlikely.
Most of the snow would be the result of low-level cold air condensation, a pattern which usually produces light amounts (discussion continues below map).
A large mid and upper low tracking to our north will help to "open the door" to the arctic air. If this low were to drift further south, the chance of significant snow will increase, but that appears to be of only low probability at this time.
