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.

While recognized standards for placing weather stations have been
followed as closely as practical, the data may vary from official reports as well
as other stations in the area. Our data is shared with Weather
Weather Observer Project,
Other organizations may be added.
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.

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.
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.
