1976: The first WSR-74 weather radar went online in Corpus Christi, Texas. An improvement on the old WSR-57 systems, 62 would eventually be installed in the United States before being replaced by the much more advanced NEXRAD Doppler radar.

1899: In the wake of a major blizzard that affected much of the eastern United States, hundreds of cities across the country, including Dallas, New Orleans, and Atlanta, set record low temperatures that still stand today. Several U.S. state records were set as well, in Nebraska, Ohio, Texas, and most notably Florida, where Tallahassee sank to −2 °F (−19 °C); the only time on record the state has seen temperatures below zero Fahrenheit.
2007: The Valentine's Day Storm hit its peak over the eastern half of North America. Up to 48 inches (120 cm) of snow fell in Vermont and 37 people were killed. The storm system also spawned a small tornado outbreak, killing one person near New Orleans.
1967: The TIROS-9 weather satellite ended its mission. The satellite was the first of the TIROS program to be in a near-polar orbit, allowing cloud cover pictures and radiometric temperature observations to cover the entire surface of the earth over the course of several orbits.
2005: Cyclone Olaf struck areas of American Samoa, causing severe damage.
1959: Vanguard 2, the first weather satellite, was launched, carrying a device to measure daytime cloud cover.

2013: Cyclone Rusty, which brought gale-force winds to Port Hedland, Western Australia for a record 39 hours straight, made landfall near Pardoo Station.
2010: A European windstorm named Cyclone Xynthia battered Europe for the second day, causing widespread wind damage across the continent. Eventually more than €1.3 billion in damage would be attributed to the storm, and at least 51 people killed.
2004: Cyclone Monty reached its peak intensity off the Pilbara coast of Western Australia, with estimated wind gusts as high as 215 kilometres per hour (134 mph).
