PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BUFFALO NY
111 PM EDT WED AUG 24 2022

...NWS OFFICES SERVING NEW YORK AND NEW ENGLAND WILL CONDUCT AN 
EXPERIMENT THIS FALL TO IMPROVE SERVICES RELATED TO THE 
FROST/FREEZE PROGRAM... 

THE NATIONAL WEATHER SERVICE'S (NWS) FROST/FREEZE PROGRAM 
CONSISTS OF ISSUING FROST ADVISORIES, FREEZE WARNINGS, OR HARD 
FREEZE WARNINGS WHEN COLD TEMPERATURES POTENTIALLY THREATEN TENDER
VEGETATION AND CROPS DURING THE CLIMATOLOGICAL GROWING SEASON. 
THE GROWING SEASON IS DEFINED BY THE PERIOD OF TIME BETWEEN THE 
MEDIAN DATE OF THE LAST SPRING FREEZE AND THE MEDIAN DATE OF THE 
FIRST FALL FREEZE. 

CURRENTLY, THE ENDING OF THE ISSUANCE OF FROST/FREEZE HEADLINES 
FOR A SEASON IS 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 YORK AND NEW ENGLAND 
(BURLINGTON VT, GRAY ME, CARIBOU ME, BOSTON MA, ALBANY NY, BUFFALO
NY, BINGHAMTON NY, AND NEW YORK NY) WILL CONDUCT AN EXPERIMENTAL 
PROGRAM SERVICE DURING THE FALL OF 2022. THE PURPOSE OF THIS 
EXPERIMENTAL PROGRAM IS TO STREAMLINE THE FROST/FREEZE PROGRAM FOR
SIMPLIFIED CUSTOMER USABILITY. 

THIS EXPERIMENT SIMPLIFIES THE SEASON DURING WHICH FROST/FREEZE 
HEADLINES WILL BE ISSUED TO INCLUDE THE ENTIRETY OF THE 
CLIMATOLOGICALLY DEFINED GROWING SEASON AS WELL AS THE SUCCEEDING 
10 DAYS. THE END OF THE FROST/FREEZE PROGRAM WILL NOT BE BROUGHT 
ABOUT DURING THIS EXPERIMENT BY A FREEZE ACTUALLY OCCURRING TO 
BETTER ACCOUNT FOR USER’S PROTECTIVE MEASURES BEING EFFECTIVE AT 
PREVENTING VEGETATION DAMAGE FROM AN EARLY FROST OR FREEZE. 

THE FOLLOWING ARE THE CLIMATOLOGICALLY DEFINED MEDIAN DATES OF A 
FIRST FALL FREEZE AND THE END DATE OF THE FROST/FREEZE PROGRAM FOR
THE FALL SEASON FOR ALL COUNTIES IN THE NWS BUFFALO SERVICE AREA:
