Tornado Outbreak Of November 22–24, 2004
A record-breaking large and destructive tornado outbreak impacted the Southern United States at the end of November 2004. The outbreak started with numerous weak tornadoes from Central Texas through Louisiana from November 22 through the afternoon of November 23 before more significant tornadoes occurred through November 24. Over a dozen intense tornadoes touched down, including four deadly tornadoes in Texas, Louisiana, Mississippi, and Alabama. Overall, 104 tornadoes were confirmed, setting the record for the largest continuous outbreak in November. Meteorological synopsis In November and December 2004, the prevailing pattern was conducive for severe weather across the Southern United States, with a large ridge over the northern Pacific Ocean supporting a southerly storm track toward the Gulf Coast. The fall season contributed to an already active year, solidifying 2004 as the busiest year for tornadoes on record in the United States. This particular tornado outbreak bega ...

Dewpoint
The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to produce a relative humidity of 100%. This temperature depends on the pressure and water content of the air. When the air at a temperature above the dewpoint is cooled, its moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. When this occurs through the air's contact with a colder surface, dew will form on that surface. The dew point is affected by the air's humidity. The more moisture the air contains, the higher its dew point. When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed via deposition rather than condensation. In liquids, the analog to the dew point is the cloud point. Humidity If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls; this is because the air's capacity to hold wa ...

Florida Panhandle
The Florida panhandle (also known as West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida. It is a Salient (geography), salient roughly long, bordered by Alabama on the west and north, Georgia (U.S. state), Georgia on the north, and the Gulf of Mexico to the south. Its eastern boundary is arbitrarily defined. It is defined by its Culture of the Southern United States, southern culture and Rural area, rural demographics in contrast to urbanized central and southern Florida, as well as closer cultural links to Alabama and Georgia. Its major communities include Pensacola, Florida, Pensacola, Navarre, Florida, Navarre, Destin, Florida, Destin, Panama City Beach, Florida, Panama City Beach, and Tallahassee, Florida, Tallahassee. As is the case with the other eight U.S. states that have Salient (geography)#Panhandles in the United States, panhandles, the geographic meaning of the term is inexact and elastic. References to the Florida panhandle a ...

Carolinas
The Carolinas, also known simply as Carolina, are the U.S. states of North Carolina and South Carolina considered collectively. They are bordered by Virginia to the north, Tennessee to the west, and Georgia (U.S. state), Georgia to the southwest. The Atlantic Ocean is to the east. Combining North Carolina's population of 10,439,388 and South Carolina's of 5,118,425, the Carolinas have a collective population of 15,557,813 as of 2020. If the Carolinas were a single state of the United States, it would be the List of U.S. states and territories by population, fifth-most populous state, behind California, Texas, Florida, and New York. The Carolinas were known as the Province of Carolina during America's early Colonial America, colonial period, from 1663 to 1712. Prior to that, the land was considered part of the Colony and Dominion of Virginia, from 1609 to 1663. The province was named ''Carolina'' to honor King Charles I of England. Carolina is taken from the Latin word for "Char ...

Squall Line
A squall line, or quasi-linear convective system (QLCS), is a line of thunderstorms, often forming along or ahead of a cold front. In the early 20th century, the term was used as a synonym for cold front (which often are accompanied by abrupt and gusty wind shifts). Linear thunderstorm structures often contain heavy precipitation, hail, frequent lightning, strong straight-line winds, and occasionally tornadoes or waterspouts. Particularly strong straight-line winds can occur where the linear structure forms into the shape of a bow echo. Tornadoes can occur along waves within a line echo wave pattern (LEWP), where mesoscale low-pressure areas are present. Some bow echoes can grow to become derechos as they move swiftly across a large area. On the back edge of the rainband associated with mature squall lines, a wake low can be present, on very rare occasions associated with a heat burst. Theory Polar front theory was developed by Jacob Bjerknes, derived from a dense netwo ...

Interstate 10 In Texas
Interstate 10 (I-10) is the major east–west Interstate Highway in the Southern United States. In the U.S. state of Texas, it runs east from Anthony, at the border with New Mexico, through El Paso, San Antonio, and Houston to the border with Louisiana in Orange. At just under , the Texas segment of I-10, maintained by the Texas Department of Transportation, is the longest continuous untolled freeway in North America that is operated by a single authority. It is also the longest stretch of Interstate Highway with a single designation within a single state. U.S. Highway 83 is about longer than I-10 within Texas. Mile marker 880 and its corresponding exit number in Orange, Texas, are the highest-numbered mile marker and exit on any freeway in North America. Since widening was completed in 2008, a portion of the highway west of Houston is now also believed to be the widest in the world, at 26 lanes when including feeders. More than a third of I-10's length is l ...

Arkansas
Arkansas ( ) is a landlocked state in the West South Central region of the Southern United States. It borders Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, Texas to the southwest, and Oklahoma to the west. Its name derives from the Osage language, and refers to their relatives, the Quapaw people. The state's diverse geography ranges from the mountainous regions of the Ozark and Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta. Previously part of French Louisiana and the Louisiana Purchase, the Territory of Arkansas was admitted to the Union as the 25th state on June 15, 1836. Much of the Delta had been developed for cotton plantations, and landowners there largely depended on enslaved African Americans' labor. In 1861, Arkansas seceded from the United St ...

North Texas
North Texas is a term used primarily by residents of the Dallas–Fort Worth metroplex to refer to a geographic area of Texas, generally considered to include the area south of Oklahoma, east of Abilene, Texas, Abilene, west of Paris, Texas, Paris, and north of Waco, Texas, Waco. Definitions of the region typically do not include the sparsely populated Texas Panhandle, Panhandle of Texas, which is the northernmost region of Texas bordered by New Mexico to the west and Oklahoma to the north and east. 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 northern rural counties along the Red River of the South border. History Indigenous tribes in North Texas included the Caddo, Tawakoni, Wichita people, Wichi ...

Low-pressure Area
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A ...
