About This Station

The station is powered by a Davis™ Vantage Pro2™ personal weather station. The station is located in the western part Collierville, TN (see more information about this beautiful small town below). Data is collected every 2.5 seconds and the site is updated every 2 minutes. The data is collected from the Davis™ station using Mac mini® hardware running WeatherCat for Mac® software. The station is comprised of a roof-mounted, wireless, solar-powered anemometer, a backyard wireless, solar-powered, main station module containing a rain gauge, and thermo-hydro sensor. The data are transmitted to an indoor display console which also provides some indoor conditions. The Vantage Pro2™ is a highly accurate personal weather station, but may not be calibrated more than every few years.

Rain Measurements

The rain measurements are usually accurate to within 0.01 inch. Rain water is collected in a five inch funnel and drips slowly onto a “seesaw” bucket divided into two separate containers. When the bucket contains exactly 0.01 inches of water, gravity forces it down. That causes the other bucket to start collecting water.

Each time the “seesaw” tips, it passes a magnetic switch which registers another 0.01 inch of “rain”. However, if the precipitation is very light, and the humidity is very low, the “rain” may evaporate before it can form enough drops to fill even one of the “seesaw” buckets. Thus, no “rain” will be recorded, even if we humans see and feel it.

On the other hand, an unusually heavy dew may cause “seesaw” buckets to tip at least once and the station will report “rain”. Please remember, humans are more sensitive at seeing and reporting what we call “rain”!

The station can report rain amounts from 0.01 to 99.9 inches, at which time this site will most likely be inaccessible. You can also follow changes in the rate of rain fall during the rain event.

About Collierville

Source: Collierville, Tennessee

Collierville is a town in Shelby County, Tennessee, a suburb located in the Memphis metropolitan area. The town had a population of 43,965 at the 2010 census. The town has a total area of 24.6 square miles (64 square km). The town is along a major Norfolk-Southern main line that connects major East Coast sities to the western United States as well as the Pacific. Collierville is only 5 miles west of a new intermodal facility recently built by the Class 1 railroad.

Our town is home to the “Avenue at Carriage Crossing”, an 800,000+ sq ft shopping center which opened in October 2005. Baptist Hospital, Collierville, serves the medical needs of the town’s residents. Collierville will soon become part of the Interstate 69 highway plan integrating Bill Morris Parkway (SR 385) as part of this USDOT project linking Canada and Mexico with the United States.

Collierville was chosen as one of Relocate-America’s Top 100 Places to Live in 2008. In 2014, Collierville’s historic town square was ranked by Parade Magazine as the “Best Main Street” in America.

Collierville’s traditional destination for visitors is the Historic Square, in the center of downtown. This quaint shopping and park destination boasts trendy shops, fun eateries, and a tree-lined park, with a restored log house, all overlooking the train depot.

“Fair on the Square” and the annual “Symphony in the Rose Garden” both take place every May. The Summer concert series at the historic Collierville town square kicks off the first week of June and lasts through the end of July. Collierville’s Farmers Market is located just off the Town Square on Washington Street (behind McGinnis’ Station/across from Mensi’s Dairy Bar).


The Town of Collierville has been transformed many times on its journey from a small settlement to the thriving community it is today. The land that makes up the town was originally used by Native Americans, then charted by French and Spanish explorers, and finally settled by hardy pioneers.


Source: The Climate

Collierville has a humid subtropical climate, with four distinct seasons. The Summer months are persistently hot (between 68 °F (20 °C) and 95 °F (35 °C)) and humid due to moisture encroaching from the Gulf of Mexico. Afternoon thunderstorms are frequent during Summers, but usually brief, lasting no longer than an hour.

Early Autumn is pleasantly drier and mild, but can remain hot until late October. Fall foliage becomes especially vibrant after the first frost, typically November, and lasts until early December.

Late Winters are mild, but cold snaps can occur. The official all-time record low temperature was -13.0 °F (-25.0 °C), which occurred on December 24, 1963. Snowfall is not abundant but does occur during most Winters, with an annual average of 5.7 inches (14.4 cm).

Spring often begins in late February or early March, following the onset of a sharp warmup. This season is also known as ‘severe weather season’ due to a higher frequency of tornadoes, hail, and thunderstorms.
