Tornado Outbreak Of May 15–17, 2013
The tornado outbreak of May 15–17, 2013 was a small but intense and deadly tornado outbreak that produced several damaging tornadoes in northern Texas, south-central Oklahoma, northern Louisiana, and northern Alabama. In mid-May 2013, an upper-level shortwave trough tracked across the Southern Plains of the United States. An associated low-pressure area and atmospheric instability resulted in the formation of tornadoes across northern Texas and Oklahoma on May 15. Afterwards the storm system weakened as it tracked westward, though six additional tornadoes were reported in Texas, Louisiana, and Alabama in the two days following May 15. Over a period of nearly two days, the storm system produced 26 tornadoes in four states. The strongest of these was an EF4 tornado which struck Hood County, Texas on May 15. However, on May 16 and May 17 no tornadoes were confirmed to have been stronger than EF1 intensity. In addition to tornadoes, large h ...

Tornadoes Of 2013
This page documents the tornadoes and tornado outbreaks of 2013. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season, and somewhat regularly in Europe, Asia, and Australia. There were 916 tornadoes confirmed in the United States in 2013. A total of 115 fatalities were confirmed worldwide in 2013: 55 in the United States, 36 in Bangladesh, 24 in China, three in Turkey and two in Brazil. One of these tornadoes was the largest ever at 2.6 miles wide. Despite the high death toll along with several large outbreaks, the year was below average in terms of the number of tornadoes that occurred. On April 1, Canada began utilizing the Enhanced Fujita scale to rate tornadoes with minor modifications to better suit the region's tornadoes. Synopsis E ...

Supercell
A supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to away. They tend to last 2–4 hours. Supercells are often put into three classification types: classic (Normal precipitation level), low-precipitation (LP), and high-precipitation (HP). LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United Stat ...

Cleburne, Texas
Cleburne is a city in and the county seat of Johnson County, Texas, United States. As of the 2010 census, its population was 29,337. The city is named in honor of Patrick Cleburne, a Confederate general. Lake Pat Cleburne, the reservoir that provides water to the city and surrounding area, is also named after him. History Cleburne is Johnson County's third county seat (the first being Wardville, now under Lake Pat Cleburne). It was formerly known as Camp Henderson, a temporary Civil War outpost from which Johnson County soldiers would depart for war (most of them served under General Cleburne). The city was formally incorporated in 1871. Cleburne was near the earliest road in the county. The location featured water from West Buffalo Creek, making it a stop for cattlemen from the Chisholm Trail. In August 1886, the Texas Farmers' Alliance met at Lee's Academy and adopted a 17-point political resolution, commonly known as the Cleburne Demands, which was the first major docum ...

Severe Thunderstorm Watch
A severe thunderstorm watch ( SAME code: SVA) is a severe weather watch product issued by regional offices of weather forecasting agencies throughout the world when meteorological conditions are favorable for the development of severe thunderstorms as defined by regional criteria that may contain large hail, straight-line winds, lightning, intense hydrological phenomena and/or tornadoes. A severe thunderstorm watch does not necessarily mean that severe weather is actually occurring, only that conditions present a credible risk for thunderstorms producing severe weather phenomena to affect portions of the watch area. A watch must not be confused with a severe thunderstorm warning. Definition A ''severe thunderstorm watch'' indicates that atmospheric conditions observed in and close to the watch area have created a significant risk for the development and intensification of convective thunderstorms that could exceed regional severe criterion, and are normally issued in advance o ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Texas
Central Texas is a region in the U.S. state of Texas surrounding Austin and roughly bordered by San Saba to Bryan and San Marcos to Hillsboro. Central Texas overlaps with and includes part of the Texas Hill Country and corresponds to a physiographic section designation within the Edwards Plateau, in a geographic context. Central Texas includes the Austin–Round Rock, Killeen-Temple-Fort Hood, Bryan–College Station, and Waco metropolitan areas. The Austin–Round Rock and Killeen-Temple-Fort Hood areas are among the fastest-growing metropolitan areas in the state. The Greater Austin and Greater San Antonio areas are separated from each other by approximately along Interstate 35. It is anticipated that both regions may form a new metroplex similar to Dallas and Fort Worth. Some of the largest cities in the region are Austin, College Station, Killeen, Round Rock, and Waco. The largest U.S. Army installation in the country, Fort Hood, is located near Kil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Texas
North Texas (also commonly called North Central Texas) is a term used primarily by residents of Dallas, Fort Worth, and surrounding areas to describe much of the north central portion of the U.S. state of Texas. Residents of the Dallas–Fort Worth metroplex generally consider North Texas to include the area south of Oklahoma, east of Abilene, west of Paris, and north of Waco. A more precise term for this region would be the northern part of the central portion of Texas. It does not include the Panhandle of Texas, which expands further north than the region previously described, nor does it include most of the region near the northern border of Texas. Today, North Texas is centered upon the Dallas–Fort Worth metroplex, the largest metropolitan area in Texas and the Southern United States. People in the Dallas and Fort Worth areas sometimes use the terms "Metroplex", "DFW", and "North Texas" interchangeably. However, North Texas refers to a much larger area that includes many ...
