The bad weather that returned to northern Greece early Sunday morning with snowfall on the mountains and a sharp drop in temperatures in lower altitudes and coastal regions, is continuing to worsen, Monday evening.

Prime minister, Alexis Tsipras, said on Sunday he would not accept an extension to Greece's current bailout, setting up a clash with EU leaders - who want him to do just that - at a summit on Thursday.

Greece’s exit from the euro is just a matter of time because no one wants to risk lending money to the country any more, said former Fed chairman Alan Greenspan.
