weather prediction center wikipedia

The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service... government. Until March 5, 2013, the Weather Prediction Center was known as the Hydrometeorological Prediction Center (HPC). The Weather Prediction Center serves as a center for quantitative precipitation forecasting, medium range forecasting (three to eight days), and the interpretation of numerical weather prediction computer models. The Weather Prediction Center issues storm summaries on storm systems bringing significant rainfall and snowfall to portions of the United States. They also forecast precipitation amounts for the lower 48 United States for systems expected to impact the country over the next seven days.

Advisories are also issued for tropical cyclones which have moved inland, weakened to tropical depression strength, and are no longer the responsibility of the National Hurricane Center. The Weather Prediction Center also acts as the backup office to the National Hurricane Center in the event of a complete communications failure. Long range climatological forecasts are produced by the Climate Prediction Center (CPC), a branch of the National Weather Service. These include 8–14 day outlooks, monthly outlooks, and seasonal outlooks. From the early days of organized weather collection in the United States, a central facility was used to gather and disseminate data. Originally, this task occupied[when?] a single room within the United States Army Signal Service in Washington, D.C.

Reports were collected via telegraph and general forecasts were made for the country.[citation needed][1] While WPC's roots lie deep in the past,[when?] the organization can be most directly traced to the formation of the Analysis Center by Circular Letter 39-42, signed by Weather Bureau director Francis W. Reichelderfer on March 5, 1942.[2][3] Operations began on March 16, 1942, with the unit collocated with the Weather Bureau Central Office at 24th and M Streets NW in Washington, D.C.[4] Initially the unit was...

The NWS performs its primary task through a collection of national and regional centers, and 122 local Weather Forecast Offices (WFOs).

As the NWS is an agency of the U.S. federal government, most of its products are in the public domain and available free of charge. Early attempts to record weather information can be traced back to Joseph Henry of the Smithsonian Institution, who, after a tornado in Jefferson, Illinois (modern-day Des Plaines, Illinois), in 1855, wrote to the Daily... Organized large-scale weather recording by the Smithsonian led to the creation of the U.S. Signal Service, the earliest predecessor of the modern-day National Weather Service.[12] In 1869, Cleveland Abbe, then director of the Cincinnati Observatory, began developing and issuing public weather forecasts (which he called "probabilities") using daily... This effort was undertaken in cooperation with the Cincinnati Chamber of Commerce and Western Union, which he convinced to back the collection of such information.

Meanwhile, Increase A. Lapham of Wisconsin lobbied Congress to create a storm warning service, having witnessed the destructive power of storms in the Great Lakes region.[13] Representative Halbert E. Paine introduced a bill authorizing the secretary of war to establish such a service. On February 9, 1870, the first official weather service of the United States was established through a joint resolution of Congress signed by President Ulysses S. Grant[14] with a mission to "provide for taking meteorological observations at the military stations in the interior of the continent and at other points in the States and Territories... and for giving notice on the northern (Great) Lakes and on the seacoast by magnetic telegraph and marine signals, of the approach and force of storms." The agency was placed under the secretary of...

Army Signal Service under the chief signal officer, Brigadier General Albert J. Myer. Myer gave the National Weather Service its first name: The Division of Telegrams and Reports for the Benefit of Commerce.[16] In November 1870, Myer hired Lapham as the first civilian assistant to the new service, but Lapham left less than two years later. Abbe joined as the second civilian assistant to Myer in January 1871 and began developing a system for national forecasts, based on his work in Cincinnati, which he began issuing the following month.[17] Throughout... The agency first became a civilian enterprise in 1891, when it became part of the Department of Agriculture and its name officially became the U.S.

The SPC's core function is to forecast severe weather events, particularly tornadoes, severe thunderstorms, and related hazards, across the contiguous United States. It provides forecasts and warnings to inform the public, emergency management agencies, and other stakeholders about potential severe weather risks, playing a critical role in mitigating damage and saving lives.

In 1952, the Storm Prediction Center began as the Severe Local Storms Unit (SELS) within the U.S. Weather Bureau in Washington, D.C. In 1954, the Severe Local Storms Unit moved its forecast operations to Kansas City, Missouri. In 1955, the Severe Local Storms Unit began issuing convective outlooks for predicted thunderstorm activity. In 1960, the Severe Local Storms Unit began issuing radar summaries in three-hour intervals.
