Mist in Slavic languages

It's funny to notice how different Slavic languages deal with the word for mist or fog. Sometimes it looks as though four letters (g is a Czech/Slovak innovation from general Slavic g) were scattered over a table and each Slavic language combined them haphazardly. Czech has mlha, but Polish and Russian have mgła and мгла (mgla), respectively, whereas Slovak has hmla.
