Winter 2007/08: Warm and Dry

Near Record Warm Temperatures and Low Rainfall Define February

The persistent, progressive pattern of flat high pressure ridges, punctuated by similarly fast-moving cyclones, in the middle levels of the atmosphere (generally between 15,000 and 25,000 feet) racing through Texas, maintained what sometimes felt like a ceaseless wind which predominated from the south or southeast much of the time, as the cyclones tended to lift well north of the Rio Grande Valley. In February, the southerly flow dominated most, resulting in top ten highest average temperatures for the three primary climate locations of Brownsville, Harlingen, and McAllen (Tables, below). A brief summary of the winter statistics for these locations follows.
