December 2004

Print Email

December was a fitting end to an exciting year of weather. The month began with much cooler than normal temperatures and little precipitation. A low pressure system brought some warmer temperatures and moderate rainfall to the Brazos Valley. A high pressure settled over the state, and temperatures warmed up quite a bit. A cold front hit the area beginning on the 14th, and high temperatures dropped 10°F from one day to the next. A little bit of rain fell with the front, as well and temperatures again warmed to the 70s before a large trough hit the state. Temperatures plummeted as a large arctic air mass settled over Texas, and while many parts of the state received snow, College Station remained relatively dry over Christmas. On the 23rd and 25th, the low reached 25°F, the coldest temperature all year in College Station. Following the cold snap, temperatures warmed back up into the 70s, some 15-20°F above normal. Unlike most of a very wet 2004, only 1.07" of rain fell in College Station, 2.16" below the December normal. For the entire year, College Station received 56.18" of rain, the 3rd highest total in College Station history and only 4.86" behind the 1968 record.
