The farming/gardening season is getting underway and typically in this part of the country, the last spring freeze occurs between April 19th and May 3rd.  The National Climatic Data Center (NCDC) also produces frost and freeze maps and these can be found at:  http://www.ncdc.noaa.gov/oa/climate/freezefrost/frostfreemaps.html

When necessary, the National Weather Service will issue a
