Dallas Deluge Demolishes Daily Downpour Data;
New January Daily Rainfall Record, Second Wettest January

Following last year's exceptional drought, the climate pendulum has jumped to the opposite extreme, bringing record rainfall and floods to portions of north Texas. Although the National Weather Service reports that the heavy rain has ended, the 3.54" of rain so far today at Dallas is nearly 3 times the old record for the date of 1.28" in 1973. The daily total is also an all-time January daily record, exceeding the 3.15" on January 4, 1998, and it's the second-highest daily total for any winter day (December-February), behind the 4.22" on December 20, 1991.

The January 2012 monthly total to date of 6.04" is approaching 4 times the normal amount of 1.66". It also surpasses the 5.58" in January 2007 to become the second wettest January, behind 9.07" in 1932.

Note: Although the Dallas/Ft. Worth climate record is considered continuous back to 1898, data have been collected at several locations in the area:
  • 1898-1940: Downtown Fort Worth
  • 1940-1953: Fort Worth Meacham Field
  • 1953-1974: Greater Southwest International Airport
  • 1974-present: Dallas/Fort Worth International Airport

One of them is Dead Horse Dam, Flathead County, Montana. They tied their record there for the hottest day ever in January. No airport, urban heat island.
