According to the National Weather Service in Upton, NY the 36.0″ of snow recorded by the cooperative observer in Ansonia, CT during the February 8-9, 2013 blizzard is being investigated as a possible state record.
“At Ansonia, an official NWS Coop observer recorded 36.0 inches during the standard 24 hour observing period. This breaks the previously established greatest daily snowfall record for CT of 28.0 inches,” a National Weather Service statement said.
The National Weather Service went on to say, “The record set at Ansonia is currently unofficial. A state climate extremes committee has been established to analyze and certify the data.”
According to the NCDC the daily snowfall record is 28.0″ from Middletown on January 28, 1897. The 24-hour record (which is different from a daily record) is 30.0″ according to NCDC from Falls Village in 1969. It is likely that this record would be broken as well if the Ansonia, CT observation becomes official.
A daily record is from new snowfall that is measured at the start of a new observation day. A 24-hour snowfall record can be set for snowfall that fell in any 24-hour period not necessarily ending at the official observation time.
The 40″ snowfall report from Hamden was ineligible for the record since it was reported by the public and not a trained spotter or cooperative observer.
