This Po Valley fog is oppressive.
'Padana' — pa-DA-na. Adjective from 'Padano' (of the Po). 'Opprimente' — op-pri-MEN-te, stress on the third syllable.
Use in northern Italian cities (Milan, Turin, Padua, Ferrara) during autumn and winter when the famous Po Valley fog settles for days or weeks. Very regional and specific.
'Nebbia padana' refers specifically to the fog of the Po Valley (Pianura Padana). 'Opprimente' (oppressive) captures the psychological effect of grey skies for extended periods. This phrase shows regional meteorological knowledge.
