Mount Washington Observatory – Record lows temperatures expected. Wind chill Warning In Effect Through Noon EST Sunday.

MWOBS – We continue to track an extremely cold arctic front that will impact the higher summits over this forecast period. With the passage of the front, the coldest airmass of the season will usher into the region Friday through Saturday. This exceptionally cold airmass will have the potential to break several minimum temperature records, including Friday’s daily record of -32F, February’s monthly record of -46F, and even the all-time record of -47F. This extremely cold weather event will produce dangerously cold wind chill values Friday through Saturday, which will create life-threatening conditions for those hoping to travel to the higher summits. Due to the harsh cold conditions, a wind chill warning will remain in effect through noon Sunday.

The Mount Washington Observatory (MWObs) is a private, non-profit scientific and educational institution organized under the laws of the state of New Hampshire. The weather observation station is located on the summit of Mount Washington in New Hampshire. The Observatory’s mission is to advance understanding of the natural systems that create the Earth’s weather and climate, by maintaining its mountaintop weather station, conducting research and educational programs and interpreting the heritage of the Mount Washington region. The first regular meteorological observations on Mount Washington were conducted by the U.S. Signal Service, a precursor of the Weather Bureau, from 1870 to 1892. The Mount Washington station was the first of its kind in the world, setting an example followed in many other countries.
