October 2012 Sees Below Normal Temperatures & Precipitation

Temperatures

While not as anomalous as 2011, much of 2012 has seen above normal temperatures across West Central Texas.  The good news is that both San Angelo and Abilene recorded an average monthly temperature below the 30 year normal for the first time this year.  The last time either month was below normal was in December of 2011.

In 2012, San Angelo recorded an average temperature 3.2 degrees above normal through Oct 31 (compared to 4.4 degrees through the same date in 2011).  Based on the climatological records of the period January 1 - October 31, 2012 will go down as the 3 warmest year on record, trailing only 2011 and 2000. 

Abilene has also registered an average temperature 3.2 degrees above normal (compared to 3.6 degrees last year).  Like San Angelo, Abilene in 2012 experienced its 3rd warmest January through October period on record (also behind 2011 and 2000).

 Precipitation

October was a slow month for both San Angelo an Abilene. Rainfall during the month of October was more than 2" below normal in both cities. However, for the year both San Angelo and Abilene are doing well in regard to rainfall amounts. In fact, through the end of October, both San Angelo and Abilene are running above normal on rainfall. Of course, this is thanks in large part to the wet period at the beginning of the year and the record rainfall that fell across the area in late September.

 

San Angelo's total for the year (21.78") is already above the annual normal.  At the end of October 2011, San Angelo had received less than half of that toal (7.91").  Abilene received 22.87" of rain through October 31 this year, compared to 14.72" through that time last year.  This puts Abilene's year-to-date total slightly above normal (through October) with 2 months to go.  An interesting statistic is that Abilene received exactly the same amount of rain during September and October of 2012 (9.21") as San Angelo did during the entire year of 2011.
