For much of the northeast United States, Valentine's Day was the coldest on record, with people bundling up for the not-so-warm embrace of teeth-chattering temperatures.
From New York and Boston to Providence, Rhode Island and Hartford, Connecticut, temperatures on Sunday morning (local time) dipped to as low as -40degC -- on Mount Washington in New Hampshire.
The National Weather Service said the temperature in New York City's Central Park fell to -15degC, a record low for the date.
Boston reached -23degC, breaking the record set in 1934 of -18.5degC.
It reached -26.5degC in Worcester, Massachusetts, breaking the 1979 record of -24degC. Providence hit -23degC and Hartford -24.5degC, also breaking records from 1979.
In Montpelier, Vermont, the overnight temperature hit -28.5degC, tying a record set in 2003. And South Lincoln, Vermont, recorded -33degC.
Temperatures were so low in some spots they knocked out utilities.
A frozen regulator left about 400 customers in Connecticut without natural gas service and officials believe extreme cold in Vermont broke a utility pole, knocking out service to about 1500.
The cold kept many people inside.
Temperatures were expected to climb before a winter storm already bringing snow to the Midwest moves into the region.
