Marion, Illinois Tornado Outbreak
The Marion, Illinois tornado outbreak was a small, severe tornado outbreak that affected southern portions of the Midwestern United States on May 29, 1982. Tornadoes touched down in the states of Illinois, Missouri, and Indiana, with Marion, Illinois, being the hardest hit. Ten fatalities occurred there after the town took a direct hit from an F4 tornado. The outbreak also produced an F3 tornado affecting the Conant, Illinois, area and several weaker tornadoes in the surrounding area. Meteorological synopsis On the 12:00 UTC surface chart, a cold front was draped from Minnesota southwest across Iowa, Kansas, Oklahoma, and into Texas. A triple point was found just south of Des Moines, Iowa, with a warm front positioned east across northern Illinois and Indiana. Morning dew points ranged from at Saint Louis, Missouri, and Louisville, Kentucky, to at Memphis, Tennessee. dew points were found in Fort Smith, Arkansas, Springfield and Cape Girardeau, Missouri, and Fort Campbell ...

Tornadoes Of 1982
This page documents the tornadoes and tornado outbreaks of 1982, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Synopsis Numbers for 1982 were slightly above average, both in terms of number of tornadoes and number of fatalities. Probably the most notable tornado events of the year was the April 2–3 tornado outbreak resulting in 29 fatalities primarily in Texas and Oklahoma and the May 29 Marion, Illinois tornado which killed ten people. Events Confirmed tornado total for the entire year 1982 in the United States. January Throughout January, 18 tornadoes were confirmed across the United States. This is above the annual average of 15. January 3–4 In early January, a major winter storm affected nearly the entire Contiguous United States, including widespread bl ...

Interstate 57
Interstate 57 (I-57) is a north–south Interstate Highway in Missouri and Illinois that parallels the old Illinois Central Railroad for much of its route. It runs from Sikeston, Missouri, at I-55 to Chicago, Illinois, at I-94. I-57 essentially serves as a shortcut route for travelers headed between the South (Memphis, New Orleans, etc.) and Chicago, bypassing St. Louis, Missouri and Springfield, Illinois. Between the junction of I-55 and I-57 in Sikeston and the junction of I-55 and I-90/I-94 in Chicago, I-55 travels for , while the combination of I-57 and I-94 is only long between the same two points. In fact, both the control cities on the overhead signs and the destination mileage signs reference Memphis along southbound I-57, even as far north as its northern origin at I-94 in Chicago. Likewise, at its southern end, Chicago is the control city listed for I-57 on signs on northbound I-55 south of Sikeston, even though I-55 also goes to Chicago. , I-57 has no spur rout ...

Minnesota
Minnesota () is a state in the upper midwestern region of the United States. It is the 12th largest U.S. state in area and the 22nd most populous, with over 5.75 million residents. Minnesota is home to western prairies, now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed, and settled; and the less populated North Woods, used for mining, forestry, and recreation. Roughly a third of the state is covered in forests, and it is known as the "Land of 10,000 Lakes" for having over 14,000 bodies of fresh water of at least ten acres. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub. With a population of about 3.7 million, the Twin Cities is the 16th largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas in the state include Duluth, Mankato, Moorhead, Rochester, and ...

Louisville, Kentucky
Louisville ( , , ) is the largest city in the Commonwealth of Kentucky and the 28th most-populous city in the United States. Louisville is the historical seat and, since 2003, the nominal seat of Jefferson County, on the Indiana border. Named after King Louis XVI of France, Louisville was founded in 1778 by George Rogers Clark, making it one of the oldest cities west of the Appalachians.

Dew Point
The dew point is the temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content. When cooled below the dew point, moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. When this occurs via contact with a colder surface, dew will form on that surface. The dew point is affected by humidity. When there is more moisture in the air, the dew point is higher. 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 less vapor is needed to saturate the air. In normal conditions, the dew point temperature will not be greater than the air temperature, sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warm Front
A warm front is a density discontinuity located at the leading edge of a homogeneous warm air mass, and is typically located on the equator-facing edge of an isotherm gradient. Warm fronts lie within broader troughs of low pressure than cold fronts, and move more slowly than the cold fronts which usually follow because cold air is denser and less easy to remove from the Earth's surface. This also forces temperature differences across warm fronts to be broader in scale. Clouds ahead of the warm front are mostly stratiform, and rainfall defiantly increases as the front approaches. Fog can also occur preceding a warm frontal passage. Clearing and warming is usually rapid after frontal passage. If the warm air mass is unstable, thunderstorms may be embedded among the stratiform clouds ahead of the front, and after frontal passage thundershowers may continue. On weather maps, the surface location of a warm front is marked with a red line of semicircles pointing in the direction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Des Moines, Iowa
Des Moines () is the capital and the most populous city in the U.S. state of Iowa. It is also the county seat of Polk County. A small part of the city extends into Warren County. It was incorporated on September 22, 1851, as Fort Des Moines, which was shortened to "Des Moines" in 1857. It is located on, and named after, the Des Moines River, which likely was adapted from the early French name, ''Rivière des Moines,'' meaning "River of the Monks".

Occluded Front
In meteorology, an occluded front is a type of weather front formed during cyclogenesis. The classical and usual view of an occluded front is that it initiates when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface. The point where the warm front becomes the occluded front is the ''triple point''; a new area of low-pressure that develops at this point is called a ''triple-point low''. A more modern view of the formation process suggests that occluded fronts form directly without the influence of other fronts during the wrap-up of the baroclinic zone during cyclogenesis, and then lengthen due to flow deformation and rotation around the cyclone as the cyclone forms. Features and variants Occluded fronts usually form around mature low pressure areas. There are two types of front occlusions, warm and cold, depending on the temperature contrast: * In a cold occlusion, the cold air mass that over ...
