Scottish and Northern English dialect: gloomy, dark, dreary, or dull in appearance or weather; murky or shadowy.
From Middle English droumi or droume, possibly from Old Norse drumar 'darkness' or related to roots meaning 'dark' or 'obscure.' Preserved in Scots.
Droumy perfectly captures Scottish atmosphere—misty, gloomy, and murky all at once, which is why it stuck in Scottish dialect for describing the typical gray weather and dim light.
