About: December 1989 United States cold wave

The December 1989 United States cold wave was a series of cold waves into the central and eastern United States from mid-December 1989 through Christmas. On December 21-23, a massive high pressure area pushed many areas into record lows. On the morning of the 22nd, Scottsbluff, Nebraska, experienced -42 °F. The next morning, the front pushed temperatures in Houston down into the single digits. On the 24th and 25th, Miami experienced freezing temperatures and Key West tied its December low of 44 °F. The wave extended all the way into Mexico's Lower Rio Grande Valley, resulting in tens of millions of dollars in damage to the agricultural sector. The December cold wave was actually the second of the year, after a February cold wave had extended into Texas.
