The low moved further westwards than had originally been forecast, so
snowfalls were restricted mostly to the northern parts of Greece.
Alexandroupolis, Kastoria, Florina, Kilkis, Grevena, Naousa, Karditsa,
Veroia, Yannitsa, Edessa, Kozani, Ptolemaida, Katerini and the suburbs of
Thessaloniki were dressed up in white, while some problems were reported
across the road network of Macedonia. Night time temperatures were quite
low:

Kato Nevrokopi -7C
