The NWS Frost/Freeze program is to alert backyard gardening enthusiasts and small farmers to the possibility of a frost or killing freeze during the “Growing Season” which is defined as the period between the average (median) date of the last Spring Freeze and the average (median) date of the first Fall Freeze. When a Frost or Freeze is expected during the “Growing Season”, the NWS will issue a Frost Advisory or Freeze Warning respectively.
As of today, the only location in VT and northern NY that is "technically in the growing season and NWS headlines could be issued if necessary is the Champlain Valley of VT/NY until October 11th. Therefore if a frost or freeze is forecast before October 11th in the Champlain Valley, a Frost Advisory or Freeze Warning would be issued. Elsewhere, please monitor temperature forecasts.
