San Antonio also reported its wettest March ever with a monthly total of 7.06”, breaking a record of 6.12” set in March 1992. The abundant rainfall helped the low rainfall totals of February and added to the above-average totals of January.

Worth, Wichita Falls, and Shreveport, LA) were at least 5.0°F above average. The largest departure from normal was reported at Wichita Falls where the mean temperature of 61.4°F, 7.2°F above normal.
