Livestock Wx for Sept. 15, 2017
The past week was unusually dry across Texas and Oklahoma with little if any rain reported. Temperatures were unusually cool, averaging 3 to as much as 10 degrees below normal.
 La Niña Watch Issued
According to NOAA, there is a 55-60 percent chance of La Niña conditions developing during the upcoming fall and winter months.
Equatorial Pacific sea surface temperatures have recently cooled and are now about -0.6°C degrees below normal.

Many climate models indicate that La Niña conditions will persist through the winter months.

What This Might Mean – A Mild and Dry Winter?
The following images depict temperature and precipitation anomalies during La Niña winter (Dec-Jan-Feb) periods.
The image on the left indicates the actual anomaly while the image on the right the frequency of occurrence. In other words, the anomaly (left) has a higher probability of occurrence within areas shaded in orange (right).
This points towards the possibility of a significantly drier-than-normal winter over the southern tier of the U.S. including most of Oklahoma and Texas. It also indicated milder winter temperatures, especially over Texas.
