July in April: How will 2011 Rank?
Hundred–plus year Records May Fall

The following table shows where April 2011 ranks compared with periods of record for cooperative/climate sites around Deep South Texas, as of April 21st. Based on the forecast continuation of July like heat, persistent winds, and high humidity especially near the coast, there is a high confidence that many longstanding records will fall by the time April is through. For example: Harlingen, currently tied for 5th all time with a 78.8°F average, should rise above 80°F based on the forecast through the end of the month. This value would trump the current marker of 79.8°F set in 1967. Most other locations would follow suit, rising above, to, or very near their record averages listed below. A final ranking will be provided in early May, after all data are reviewed.
