This Day in National/World Weather History ...
 21 September 1588 → After an unsuccessful battle with the English fleet, the Spanish Armada encountered strong storms and high winds off the coast of Ireland on its way back to Spain. 26 ships are believed to have been lost. The remaining ships limped back to Spain defeated and demoralized, ending the reign of the once unbeatable Spanish Armada.
 21 September 1894 → A huge tornado outbreak swept from Iowa through Minnesota to Wisconsin, with an unusual number of extremely violent tornadoes. The tornado that rampaged through Kossuth County, MN, was likely an F5 as homes and farms were wiped clean from the earth.
 21 September 1909 → A category 3 hurricane crossed the Gulf of Mexico and came ashore in southern Louisiana. The storm inflicted 120 mph winds on southeast Louisiana and took its storm surge 2 miles inland. There were about 371 fatalities despite the Weather Bureau having issued its first warnings for the storm three days earlier.
 21 September 1938 → The New England Hurricane was one of the most destructive and powerful storms ever to strike southern New England. The storm roared ashore over Long Island, NY at nearly 60 mph at the time of high tide. This created a deadly tidal surge, which submerged downtown Providence, RI under 20 feet of water. Hurricane force winds were felt throughout New England, with a gust to 186 mph at the Blue Hill Observatory in Milton, MA. The Great New England Hurricane of 1938 was responsible for over 500 deaths.

August 20, 1904:

A destructive, estimated F4 tornado moved ESE from 7 miles WNW of Willow Lake, through the town, and on into Bryant. Most of the damaged occurred in those two towns. All buildings on at least three farms were blown away. One woman died in Bryant, Hamlin County, as the tornado swept across the residential west side of town. Another man was killed just west of Willow Lake, as his farm house was scattered for miles.

August 20, 1988:

More than 150,000 acres were consumed during one of many fires in Yellowstone. This was the single worst day of the fires and was later dubbed Black Saturday. More Yellowstone land burned on this day, than all other fires combined since the establishment of the park in 1872. Ash from the fires drifted as far away as Billings, Montana.
