...NWS Offices Serving New England and New York Will Continue an
Experiment This Fall to Improve Services Related to the Frost-Freeze
Program...

The Frost-Freeze program of the National Weather Service is designed
to alert local growers and gardeners of the potential of a damaging
frost or freeze for a given area during the climatologically defined
growing season. This allows people to take preventative measures for
plants and crops against potential damaging temperatures.

When a Frost or Freeze is expected during the growing season, the
NWS will issue a Frost Advisory or Freeze Warning respectively.
Actions in the Fall can help possibly prolong the growing season for
late stage vegetation.

Previously, the ending of the issuance of Frost/Freeze headlines for
a season was based on the occurrence of a freeze in one weather
forecast zone or two weeks after the median first Fall freeze date.
This approach was confusing to many users as meteorological
conditions often led to a patchwork approach of ending the NWS
frost/freeze program across multiple weather forecast zones and NWS
offices.

The NWS forecast offices serving New England and New York
(Burlington VT, Gray ME, Caribou ME, Boston/Norton MA, Albany NY,
Buffalo NY, Binghamton, NY, and New York, NY) will continue to
conduct an experimental program service during this fall season
2024. The purpose of this experimental program is to streamline the
Frost/Freeze program for simplified customer usability.

Just like last year, this experiment means that fall Frost/Freeze
headlines will be issued up to 10 days beyond the median date of the
first freeze. This corresponds to the 75th to 90th percentile of the
first freeze date, established by using 30 year temperature averages.

The following are the climatologically defined areas and their
respective 75th to 90th percentile of a first fall freeze, after
which Frost/Freeze headlines will no longer be issued.

November 1st: Interior Southern Connecticut, Lower Hudson Valley,
Interior NE New Jersey.

November 11th: Suffolk, Northern Nassau, and Southern Westchester
Counties, Coastal Connecticut, and Eastern Bergen, Essex, and Union
counties

November 21st: New York City, Southern Nassau County and Hudson
County
