It's impossible to predict exactly when the most frigid day of the year will be, but based on historical data, we have a good idea of when North Dakotans should plan on using one of those coveted sick days to stay in bed.

The folks at NOAA's National Climatic Data Center have compiled data for the last 30 years and identified the rough timeframe of the coldest days of the year across the country. They considered a number of climatological variables, including the average low temperature for every day. From the values, scientists can determine which day of the year, on average, has the lowest minimum temperature.

In North Dakota, it's looking like we can expect the coldest day to fall anywhere between January 1-25, depending on where you live. In Bismarck-Mandan, our coldest day is predicted to fall between January 16-20.

So while it's not exactly earth-shattering information (it is January in North Dakota, after all), you may want to consider marking those days with a big, red 'X' and just plan on staying in bed.
