Some of the county soil survey bulletins have tables that
display average last frost date and so forth. The benefit
of these tables is they show a range of dates based on
percentage chance of frost and degree of frost temperatures. Other bulletins describe weather data in text.
The average last frost date is when the spring days have
progressed to the point where there is a 90% chance of
frost-free weather, with a 10% chance of a remaining frost.
The extension service publications use established weather
data from government sources.
Some of the county soil survey bulletins are now digitized.
See:

Washington County, Arkansas, where I live, is one of the few
counties in AR that is completely digitized. The "Manuscript"
portion of the soil survey contains all the introductory tables
and descriptions, with factual data about the county, agriculture,
and climate.
The National Weather Service / NOAA is a good source for
regional data.

Does anyone know who determines the last/first frost dates? Is it the USDA or individual coop extension offices?
Thanks in advance for the info.
