It's been a brutally cold few days for people across the Northeast, but that's nothing compared to the current summit conditions at Mount Washington. It was so cold Saturday morning, it tied for second coldest place on earth according to the Mount Washington Observatory. 

Temperatures at the summit dropped to minus 36 Fahrenheit, with the wind chill an incredible minus 90 below.

The country has been gripped in a cold snap as temperatures across the Northeast are expected to remain frigid through the weekend. Burlington, Vermont saw temps drop to minus 1 with a wind chill of minus 30. New York residents shivered through Saturday as the mercury there dropped to 8 degrees with a wind chill of minus 9. 

Hartford, Connecticut saw temps drop to 10 degrees with a brutal wind chill of minus 20. 

The good news? Sunday is supposed to be the last day of the deep freeze. According to the National Weather Service, a moderation trend in temperatures is expected to begin on Monday and continue through midweek. 

The Mount Washington observatory took its historic moment to briefly explain the difference between ambient air temperatures, and wind chills. 

To clear up some recent misinformation circulating: 

Coldest ambient air temp so far: -33.9F 

Coldest calculated wind chill so far: -89F ( 

Fri daily record low is -37F (1959) 

Sat daily record low is -38F (1959) 

Wind chills don't count as records lows. 

The observatory, located on the summit of Mount Washington in New Hampshire, is meant to help scientists observe the natural systems that are part of the planet's natural climate cycle. Founded in 1932, the Mount Washington station was the first of its kind in the world, setting the example for other weather observatories that have followed.
