August 2012

Print Email

As expected, August was hot all across the state of Texas. Temperature anomalies generally increased from east to west, with the highest anomalies in the Trans-Pecos and Edwards Plateau regions and the lowest anomalies in the extreme northeast Panhandle and East Texas. Precipitation came in two distinct events, though accumulations were isolated for the most part. The majority of the rainfall that fell across the state came after a weak high pressure brought significant moisture and rainfall to south and central Texas. The other big story for the month of August was an unusually strong cold front, which passed across Texas from August 18-20, dropping temperatures by nearly 20 degrees for much of the state and providing isolated rainfall accumulations throughout East Texas. Remnants of the system provided rain for the Low Rolling Plains west of Wichita Falls in the following days.

Drought conditions intensified in the Panhandle and the Big Country, which experienced low precipitation accumulations and high temperatures; the same can be said of the Coastal Bend and Lower Valley near Corpus Christi and southward, which has seen significant drying out over the month. The aforementioned precipitation events dropped the most rainfall in the eastern Trans-Pecos and North Central Texas near Dallas-Fort Worth, both of which saw conditions generally improve by the end of August.
