I believe its TSSN and its only the intensity of the thunder/lightning thats
noted?

-TSSN (light thunder) or +TSSN (heavy thunder) as thunder is given priority
over snowfall (it has a higher synop code number)

someone correct me!

Good morning all.

Light snow accompanied by frequent lightning (SNTS?) over Athens since a
few
hours. Snowfalls are moderate in the northern suburbs and heavy at times
in
the northernmost ones and the surrounding hills and mountains. Blowing
snow
and freezing fog in the northernmost suburbs, too.
