Did you know that East and Northeast Texas received two to four times the normal amount of rainfall in July? Unfortunately, the other half of the State did not do as well, as some places in West Texas only received a half an inch of rain. With the increase in rains in Eastern areas of the State, Lake Travis saw 78,000 acre-feet of runoff pour into the basin! Even with that amount of runoff, Lake Travis still remains at less than 50% full. The figure below shows the reservoir storage for Lake Travis. In looking at the figure, our numbers are above where we were for 2023 and a little bit more than where we were in 2011.
La Niña has been the dominant subject of the summer. According to this month’s update, projections are suggesting a shift to La Nina in mid-to-late summer. Looking at the figure below, there is a 45% chance that La Nina occurs during the July-August-September months. Moving ahead on the figure, we can see that shifting one month over, there is a 70% chance of those La Niña conditions occurring in August-September-October months.
Looking ahead at the three month drought outlook, you can see in the figure below, that West Texas will remain in drought conditions. There is also the possibility for drought conditions to develop in the Northern Panhandle.
In looking at the 3-month precipitation forecast, Texas does not look to be receiving a greater chance of rain. As you can see, the East Coast is set to have above normal chances of rain, with East Texas catching a tail end of that wave. On the other side of that, the Northern Panhandle is forecasted to receive less than normal rainfall. The figure below explains more of the 3-month forecast.
