How do I get climate data for Middle Tennessee?

A wide range of climate information is now available from the NOWData tab on our climate page. You can access daily record extremes, monthly normals, daily data for a month, and a great deal more. This information is available for several Middle Tennessee cities. (For Nashville's entire period of record, use "Nashville Area." If you select "Nashville Intern," you will only get data for the airport, which goes back to 1940.) This data is updated daily, so the information the NWS makes available is constantly being refreshed.

In order to access daily record extremes, for example, simply select a city, then "Calendar day summaries," enter "POR" for the year range if you want the entire period of record, or a specific range of years if you want to limit your search, then select a vaiable such as max temp, min temp, precipitation, etc., and under "Summary" select daily maximum or daily minimum if you want record highs or lows. The click on "Go" to get the data you specificed.

In order to access the 30-year climate normals for a station, just select the location, then "Daily/monthly normals," and follow your options from there. If you choose daily normals, you can use your mouseover on the graph to get a day-by-day readout.

To access daily data for a month, select that option after specifying your location, then use the drop-down calendar by clicking on the calendar icon to select the month and year you want data for.

If you want to know, for example, the driest or wettest January's on record for your station, select a location, then select "Monthly summarized data" under "Products," enter "POR" to specify the entire period of record, select "Precipitation" as your variable, then under "Summary" select "Sum" to get the monthly rainfall totals, then click "Go." Once the data table comes up, just click on the column header "Jan," and the data will automatically sort from least to greatest. Click it again to have it sort from greatest to least. You can do this for monthly average temperatures, snowfall, etc.

There are many other datasets available using the NOWData page, as you can see from the list of options. E-mail the webmaster if you require further assistance.
