An arctic cold front moved across Vermont on the 24th and delivered very cold temperatures of zero to 25 degrees below zero by the morning of the 25th. However, on the night of the 25th into the morning of the 26th, a secondary cold front combined with a strengthening area of low pressure near New Brunswick, accounted for the combination of brisk northwest winds of 10 to 15 mph and temperatures 5 to 20 degrees below zero for wind chill readings of 25 to 40 degrees below zero.
Some morning lows on the 25th included: -29 degrees in Island Pond (Essex), -21 degrees in Sutton (Caledonia) and Morrisville (Lamoille), -19 degrees in East Haven (Essex), Canaan (Essex) and Enosburg Falls (Franklin), -15 degrees in Greensboro (Orleans), -14 degrees in Montpelier (Washington), East Albany and Newport (Orleans), -10 degrees in Bethel (Windsor), Westford (Chittenden) and Alburgh (Grand Isle).

Some morning lows on the 26th included: -20 degrees in Island Pond, East Haven, Canaan (Essex) and Sutton (Caledonia), -16 degrees in East Albany (Orleans), -15 degrees in Montpelier (Washington), -14 degrees in St. Johnsbury (Caledonia) and Eden (Lamoille) with -11 degrees in South Lincoln (Addison), Woodstock (Windsor), Rutland (Rutland) and the NWS office in South Burlington (Chittenden). Northwest winds of 10 to 15 mph created wind chill values of 25 to 40 degrees below zero.
The cold wave diminished slightly on the 27th-29th, due to a slight airmass modification and clouds across the region, but it still remained some 10 to 20 degrees below normal. However, another arctic front pushed across the area on the 29th with a replenishment of arctic air that brought early morning low temperatures on the 30th of 10 to 30 degrees below zero. Some morning low temperatures on the 30th included; -32 degrees at Island Pond (Essex), -27 degrees in Sutton (Caledonia), -25 degrees in East Haven (Essex), -24 degrees in Enosburg Falls (Franklin), -22 degrees in Morrisville (Lamoille) and -18 degrees in Hanksville (Chittenden) and Newport (Orleans).
