If you've been woken up in the early hours of Sunday morning ... this is why.
A massive storm system has developed, covering two-thirds of Minnesota with the strongest storms running a curve across the bottom half of the state, with the tip in the Twin Cities.
Heavy rain and strong winds arrived in the city at around 5 a.m., bringing with it lightning and some loud thunder.
The National Weather Service said rain could fall at a rate of 1-2 inches an hour, with wind gusts reaching 30-40 mph.
It has issued a hazardous weather outlook for numerous counties, most of them in central and southern Minnesota, saying that hail is also a possibility.
After the storm ends, the pressure will continue to build as it gets hot in the Twin Cities and Minnesota Sunday afternoon, with heat indices pushing 100 expected in parts of the state.
Start of a stormy week
Sunday morning's storm is just the first of many likely this week. During Sunday scattered storms are expected across central Minnesota, some of which could turn severe.
But then the humidity and heat will continue to build, with the NWS saying "several rounds of thunderstorms are expected throughout the upcoming week."
The worst of these is most likely to come on Monday evening and night, when "damaging winds, large hail and heavy rainfall appear possible," the NWS says, and "a few tornadoes could also occur."
It comes after massive storm on Tuesday caused localized flooding, blew multiple trees down as well as power lines, shutting off electricity to more than 140,000 homes.
