Another round of rainfall on February 24th and 25th combined with previously high humidity and one last shot of chilly temperatures allowed additional top soil permeation to close the month.  By the 21st, previously Extreme (D3) to Exceptional (D4) conditions had improved to Severe (D2) to Extreme (D4) for most of the region, with a small pocket of Starr County dipping to Moderate (D1) for the first time in nearly a year.
After more than a year of well below average precipitation (save for June and December 2011), February's copious rainfall of a general 3 to 5 inches Valley-wide ranked in the top ten wettest all time, and provided much needed drought relief. Despite the rain, most areas remained in critical drought (D2 or greater) at month's end.
