New York ( CNN ) -- Cold air swinging south from Canada left residents from North Dakota to New York contending with severe weather that proved deadly in some areas . `` Those people who work outside have to be careful , '' CNN meteorologist Chad Myers said Wednesday . Authorities say exposure to sub-freezing temperatures left at least three people dead in Wisconsin , Minnesota and Illinois . The coldest air so far is in northwestern Quebec , where temperatures plummeted to 45 degrees below zero Fahrenheit in the city of Rouyn , according to forecasters . `` We feel the wind chill , and so do pets . You need to find some place indoors and out of the wind for them , '' Myers said . In the northern Maine town of Presque Isle , temperatures hung around 24 below . And in Grand Forks , North Dakota , residents bundled up to stave off a potentially deadly wind chill that hovered even lower -- around 33 below . `` The biggest thing is staying out of the wind . That 's what kills you , '' said Michael Lannen , who works at a Menards hardware store in Grand Forks . `` It seems we get one of these kinds of weeks every year , so everyone is just trying to bundle up and stay indoors .
