Specific information for Louisville, Lexington, Bowling Green, and Frankfort.
Below is a series of maps showing average first and last dates for selected temperature thresholds. Data were taken from about fifty area observing sites. The data used were from each site's entire period of record (often stretching back into the 19th Century), and thus are averages rather than normals. Due to the limited number of points for which data are available, there is some "bullseyeing" on the map. These maps are for general information purposes only. For more precise information for your exact location, consult the Kentucky Climate Center or the Indiana State Climate Office.

Preliminary Local Climatological Data
The Preliminary Local Climatological Data Sheet summarizes temperature, heating and cooling degree days and precipitation and snowfall. This is preliminary unofficial data compiled within our office, and may contain erroneous or incorrect data.
Official published climatological data can be obtained from the National Centers for Environmental Information (NCEI) in Asheville, North Carolina for about 300 locations nationwide for a small charge. The data can be purchased via the Internet, for both online display, or hard-copy printout as well. Official monthly publications also contain 3-hourly weather observations for that month and an hourly summary of precipitation. Annual LCD publications contain a summary of the past calendar year as well as historical averages and extremes. Please note that Official LCDs are not available for FFT and BWG.
