Aquifer

Shelby County is located over four natural aquifers, one of which is recognized as the "Memphis sand aquifer" or simply as the "Memphis aquifer". This particular water source, located some 350 to 1100 ft (100 – 330 m) underground, is stated to contain more than 100 trillion gallons (380 km³) of water by Memphis Light, Gas, and Water, which draws, verifies the cleanliness of, and distributes the water to over 250,000 customers.[3]

Furthermore, in the time since the tapping of the well in 1887, the aquifer has only descended 125 ft (38 m), suggesting a reliable water source in Memphis for years to come.[4]

Most Memphians recognize this as their primary water source, and take great regional pride in their possession of the aquifer. Memphis water is notably soft, low in mineral content, and free of toxic substances.[5]

Memphis has a humid subtropical climate, with four distinct seasons. Historically, April is the month with the highest frequency of tornadoes, though tornadoes have occurred every month of the year. Memphis is sunny approximately 64% of the time.

Spring

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 the higher frequency of tornadoes, hail, and thunderstorms producing winds greater than 58 miles per hour (93 km/h). Average rainfall is slightly higher during the spring months than the rest of the year (except November), but not to any noticeable extent.

Summer

The summer months (late May to late September) are dominated by temperatures between 68 °F (20 °C) and 95 °F (35 °C), and humidity due to moisture encroaching from the Gulf of Mexico. Afternoon thunderstorms are frequent during some summers, but usually brief, lasting no longer than an hour.

Autumn

Early Autumn is pleasantly drier and mild, but can remain hot until late October. Abrupt but short-lived cold snaps are common. Late Autumn is rainy and colder, December being the third rainiest month of the year. Fall foliage becomes especially vibrant after the first frost, typically November, and lasts until early December.

Winter

Winters are mild, but cold snaps can occur. The official all-time record low temperature was −13 °F (−25 °C), which occurred on December 24, 1963. Mild spells are sometimes warm with temperatures as high as 75 °F (24 °C) during January and February. Snowfall is not abundant but does occur during most winters, with an annual average of 4.6 inches (12 cm) at the airport. The most significant snow in many years fell on March 8, 2008 when 7 inches (18 cm) blanketed the city. While severe weather is more common in Spring, notable severe weather has occurred in winter. On February 5, 2008 a tornado killed 3 in Memphis during the 2008 Super Tuesday tornado outbreak
