The spring and fall seasons are pleasant in Dallas, as seen in this March photograph from an Oak Cliff park

The city of Dallas, Texas (USA) has a humid subtropical climate, yet the city and the surrounding part of Texas also tends to receive warm, dry winds from the north and west in the summer. In the winter, strong cold fronts from the north pass through Dallas, occasionally plummeting nightly lows between 10 °F (-12 °C) and 20 °F (-7 °C). Snowfall is seen on average three days out of the year and snow accumulation is seen two days out of the year.^[1] Occasionally, warm and humid air from the south overrides cold, dry air, leading to freezing rain, which usually causes major disruptions in the city for a day or two if the roads and highways become dangerously slick.

Tornadoes

Snow seen on the campus of Southern Methodist University

Tornadoes are perhaps the biggest threat to the city of Dallas. Dallas was most recently hit by a powerful tornado on 2 April 1957. The tornado would have likely registered as an F3.^[6] The most recent minor tornado with notable damage occurred in 1984 when a minuscule formation touched down near Lovers Lane and Greenville Avenue (which collapsed one side of an apartment building). In the spring, cool fronts moving from Canada collide with warm, humid air streaming in from the Gulf Coast. When these fronts meet over northern and central Texas, severe thunder storms are generated with spectacular lightning shows, occasional torrents of rain, hail, and at times, tornadoes. Dallas lies at the southern end of Tornado Alley, which runs through the prairie lands of the Midwest. In May 2000, the “Fort Worth Tornado” hit neighboring Fort Worth's downtown, causing severe damage to many of the city's skyscrapers (and damage to one prominent 70s-era high-rise extensive enough to elicit rejected proposals for demolition) as well as destroying some smaller buildings on the periphery of its central business district.^[7] Image File history File linksMetadata Download high-resolution version (813x600, 309 KB) The Laura Lee Blanton building on the Southern Methodist University campus during a rare snow in University Park, Texas (USA) Date captured: 22 December 2004 This photograph is the work of drumguy8800 gallery | contributions | xvisionx. ...

Floods

Major flooding occurred on the Trinity River in the years 1844, 1866, 1871, and 1890, but a major event in the spring of 1908 set in motion the harnessing of the river. On 26 May 1908, the Trinity River reached a depth of 52.6 feet (16.03 m) and a width of 1.5 miles (2.4 km).^[8] Five people died, 4,000 were left homeless, and property damages were estimated at $2.5 million.

Dallas was without power for three days, all telephone and telegraph service was down, and rail service was canceled.

The Trinity River flooding on 8 July 1908.

After the disastrous flood, the city wanted to find a way to control the reckless Trinity and to build a bridge linking Oak Cliff and Dallas. The immediate reaction was citizens and the city clamoring to build an indestructible, all-weather crossing over the Trinity. This had already been tried following the 1890 flood—the result was the "Long Wooden Bridge" that connected Jefferson Boulevard in Oak Cliff and Cadiz in Dallas, but the resulting unstable bridge was easily washed away by the 1908 flood. George B. Dealey, publisher of the Dallas Morning News, proposed a 1.5 miles (2.4 km) concrete bridge based on a bridge crossing the Missouri River in Kansas City. Ultimately a US$650,000 bond election was approved and in 1912, the Oak Cliff viaduct (now the Houston Street viaduct) was opened among festivities drawing 58,000 spectators. The bridge, at the time, was the longest concrete structure in the world.^[8] July 8 is the 189th day of the year (190th in leap years) in the Gregorian calendar. ... 1908 (MCMVIII) was a leap year starting on Wednesday (link will display the full calendar). ...
