The activity followed the similar bangs and bright flashes which startled many in the early hours of Friday, prompting some to call the police to report a possible explosion in the Capital.
The thundersnow could be heard across the city from shortly after 1am, in several bursts.
Residents took to social media, with one stating: “THUNDERSNOW!!! WW3 just broke out across Edinburgh.”
Heavy rain and hail followed, adding to already high water levels in many parts of the city.
Another resident posted on Twitter: “More of the thundersnow and lightening in #Edinburgh tonight, sounds like the sky is about to collapse, and so much hail/snow/rain. Enough 2020, please... #Thundersnow.”
According to experts at the Met Office, thundersnow is when thunderstorms form in wintry conditions and sometimes give rise to heavy downpours of snow.
This, along with the usual thunder and lightning, is called 'thundersnow'. Thundersnow is unusual only because it can only occur in a few months of the year.
