November 2004 Weather in Review

 

More flooding came in November 2004, increasing from what had occurred in the previous month of October. In reality the early part of this century and decade has shown some rainy Octobers and Novembers. After a wetter than usual October in 2004, and one that was warmer than usual for South Central Texas, November 2004 was much wetter than usual, and conditions cooled off significantly from October. November 2004 has now taken its place in the record books as the wettest November in Texas since comprehensive record keeping began in 1895. In addition, 2004 may also turn out to be the state's wettest years. According to preliminary data from the NOAA National Weather Service Southern Region Climate Center in Baton Rouge, La., November averaged 6.08 inches of precipitation across Texas. The previous record was 5.71 inches in 1902.

November 2004 ended up the wettest November of record for Austin Mabry, San Antonio and Del Rio. November 2004 was the 3rd wettest November of Record at Austin Bergstrom. Even though it was the wettest of record at San Antonio, with 9.46 inches of rain, and wettest for Del Rio with 4.71 inches of rain, the long history of Fall and Early Winter Monthly Rainfall from October to December shows months that have had between 10 and 20 inches of rain in the area. November 2004 rain at Austin Mabry was direct evidence of this with a record 14.10 inches of rain, the wettest November since 1856. Austin Bergstrom had 9.91 inches, the 3rd wettest November of Record, after 10.51 inches in November 2001 and 12.49 inches in November of 1974. Just 3 years ago, on November 15, 2001, a flood event came to the area, with very heavy rains and severe weather in the Austin Area to San Antonio. Rainfall amounts on November 15, 2001 were as follows: Austin Bergstrom 8.68 inches; Austin Mabry 7.55 inches; and San Antonio 2.18 inches. October 1998, another extreme rain example for a Fall month, brought between 15 and near 30 inches of rain. Another 15 to 30 inch rain event came to Southeast Texas in October 1994. Floods came during Christmas of 1991, when between 10 and 20 inches of rain fell in the area in December of 1991. Flooding is definitely a Fall and Winter Weather Hazard for Central and South Central Texas, and this is nothing new to the present, as history paints several events from the past before the 1990s. In the 1980s, heavy rain events came to South Central Texas in late December 1984 and December 1986. A heavy rain event affected Southeast Texas in December of 1982. In December of 1913 floods came to the area also. From December 1 to 4, 1913, widespread floods came to Central and Southeast Texas, plus parts of South Central Texas. San Marcos received 15.5 inches of rain in one day. Austin received 10.66 inches of rain on the 3rd and 4th. Some parts of San Antonio got 7 inches of rain in one day; however official amounts on December 4th, 1913 was 2.02 inches.

The wettest Novembers of Record for Austin Mabry, Del Rio and San Antonio was established in November of 2004. November 2004 was the 3rd wettest November of Record at Austin Bergstrom. The list below show the 10 wettest Novembers of record for each of these locations. In addition, rainfall comparisons for Calendar Year 2004 from January 1 to November 30 are shown, with 2004 as of November 30 all ready in the top 10 wettest years.
