The worst weather

I'd I would like to tell you about the worst weather that I've I have ever experienced. It was only the beginning of the winter. In mid-December the snow didn't did not stay for long and it quickly melted away. But suddenly, one evening there was a heavy snowfall.
As a result of this snowfall, snow drifts were formed. Because of this there were dangling wires. The lights was were turned off throughout the city. After some time the lights came back turned on, but the Internet still didn't did not work. There were rolling blackouts.
And only a week later, all everyone returned to their seats. (not sure of the context here). 

Hope corrections are ok :)
